The conference "Quantum Gravity 2020" has a deliberately broad scope. We aim to include participants from all current approaches to quantum gravity, as well as researchers working on the phenomenology of quantum gravity. The main goal of the meeting is to assess the progress made and to constructively and openly discuss open questions in our understanding of quantum gravity.
A second goal is to work towards combining the insights gained in the various approaches. In its overall goal as well as the format, this conference will differ from more specialized meetings that focus on specific quantum-gravity approaches.
We hope that this inaugural conference "Quantum Gravity" can make a contribution to bridging the gaps between quantum gravity approaches, and bring the entire community together for a constructive and fruitful exchange.
Registration for the conference is now open on the conference webpage. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

In 2001, researchers from several universities with a common interest on Lorentz Geometry met on Benalmadena in what was called "Meeting on Lorentzian Geometry".
After this first and successful meeting, the organizers decided to make this one the first of a biennial series of conferences devoted to present and discuss the last advances on Lorentzian Geometry. Since then, what ended up being called "International Meeting on Lorentzian Geometry" has grown at an impressive pace.
Currently, nine meetings have been held: Murcia 2003, Castelldefels 2005, Santiago de Compostela 2007, Martina Franca 2009 (Italy), Granada 2011, Sao Paulo 2013 (Brazil), Malaga 2016 and Warsaw 2018 (Poland).
The Department of Mathematics of the University of Cordoba has the pleasure to organize in 2020 the X International Meeting on Lorentzian Geometry (GeLoCor) in an enclave with as much history as the city of Cordoba is.
Looking forward to see you in Cordoba in June 2020 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Scientific Event H0.5 - Fundamental Physics in Space - Applications (Geodesy, Metrology, Navigation, and Others) Main Scientific Organizer: Juergen Mueller Deputy Organizer: Roberto Peron
Dear colleague, the 43rd Committee on Space Research (COSPAR) Scientific Assembly will be held on 15 - 22 August 2020, in Sydney, Australia. As scientific organizers of the COSPAR session H0.5 "Applications (Geodesy, Metrology, Navigation, and Others)" and acknowledging your expertise in the related scientific fields, we would like to cordially invite you to submit an abstract for /a solicited talk in/ session H0.5.
Event Description: In this Event, we will discuss new sensor measurement and mission concepts that apply advanced techniques for the study of the gravitational field on ground and in space. Terrestrial gravity anomalies will be determined by observing free-falling atoms (quantum gravimetry) instead of using falling corner cubes. This will open the door for a vast bundle of applications such as fast local gravimetric surveys and exploration, and the observation of Earth system processes with high spatial and temporal resolution. This technique can also be applied for future gradiometric measurements in space.
Other concepts are approaching a frontier that can be termed as "Relativistic Metrology": the precise measurement of quantities (e.g., length and time) related to spacetime dynamics. Frequency comparisons of highly precise optical clocks connected by optical links give access to differences of the gravity potential (relativistic geodesy). In future, relativistic geodesy with clocks might be applied for defining and realizing height systems in a new way, locally as well as globally. Moreover, accurate clocks help to improve the accuracy of the International Atomic Time standard TAI. They are important for all space geodetic techniques as well as for the realization of reference systems and their connections. One example of increasing importance is positioning and navigation with GNSS for terrestrial and space applications.
In addition, laser interferometry between test masses in space with nanometer accuracy - which has been recently implemented in the GRACE-FO mission - belongs to these novel concepts. For the latter, technology developed for gravitational wave detection and successfully tested in the LISA Pathfinder mission is being prepared for geodetic measurements. In the future even more refined concepts (tracking a swarm of satellites) will be implemented. We invite presentations to illustrate the principles and state of the art of these novel techniques and the application of the new methods for terrestrial and satellite geodesy (where local and global mass variations and surface deformations will be observed with unforeseen accuracy and resolution, variations that reflect changes in the Earth system), navigation and fundamental physics.
We also welcome papers for further applications and invite contributions covering the theoretical description of the new methods, introducing novel theoretical concepts as well as new modelling schemes. With our best wishes,

Second Call for Papers So far representatives of 17 countries have submitted abstracts to the sixth spacetime conference in Albena (famous Black Sea resort near Varna), Bulgaria.
The Scientific Organizing Committee invites papers from physicists, philosophers of physics and philosophers on any topic related to the nature and ontology of spacetime. As there is no main theme of the sixth spacetime conference a number of special sessions have been suggested by colleagues (http://www.minkowskiinstitute.org/conferences/2020/call.html):
- Nature of time - Flow of time; Becoming (continuation of the Special Session on Becoming and the panel discussion at the Second Hermann Minkowski Meeting on the Foundations of Spacetime Physics on Wednesday, May 15, 2019) - Is spacetime a real (physical) four-dimensional entity or a mathematical concept? - Open Questions in Spacetime Physics - The controversy over Relativistic Mass - The problem with the gravitational energy-momentum pseudotensor in general relativity - should we have a closer look at the fact that the mathematical formalism of general relativity does not yield a proper tensor of the gravitational energy-momentum? - What is the difference between matter and geometry in general relativity, semi-classical gravity, and quantum gravity? - Do Black Holes Actually Exist? - Is there a conflict between relativity and quantum mechanics? - Quantum Gravity: Where do we stand?
Depending on the number of colleagues participating in a special session, we plan to publish a volume with the talks presented at the session, which will include constructive criticism and the replies of the authors.
Contributed papers in the form of extended abstracts of between one and two pages should be emailed to 2020conference[AT]minkowskiinstitute.org by February 28, 2020. Submissions will be reviewed and sending of notification of acceptance will start on February 17, 2020 (for the abstracts submitted by the original deadline January 31, 2020).

Are you interested in understanding the nature of the densest nuclear matter in the Universe? Or in using relativity to map the surfaces of neutron stars? We welcome applications for a 3-year postdoctoral position to work on neutron star astrophysics with Prof. Anna Watts and her group at the Anton Pannekoek Institute for Astronomy (API) at the University of Amsterdam (UvA). The successful applicant will join the ERC Consolidator Grant funded project AEONS (Advancing the Equation of state Of Neutron Stars).
NASA's NICER X-ray telescope has recently delivered its first measurements of neutron star mass and radius - key probes of the dense matter Equation of State (EOS) - using the new technique of Pulse Profile Modeling (PPM). PPM combines astrophysical modeling, relativistic ray-tracing, and Bayesian inference using high performance computers to deliver not only mass and radius but also a map of the hot emitting regions on the stellar surface. Our group played a major role in this effort, and the AEONS team will continue this work, analyzing new NICER data and carrying out simulations to address the complexities that we have encountered. AEONS also looks ahead to the next generation of large-area X-ray timing telescopes. Missions such as eXTP and STROBE-X are targeting accreting neutron stars for PPM - but these pose challenges such as variability, surface pattern uncertainty, and the need to consider X-ray polarimetry data. AEONS will tackle these issues, and study how to embed PPM in a multi-messenger EOS inference framework with radio and gravitational wave constraints. If you have a background in electromagnetic / gravitational wave neutron star astrophysics, dense matter physics, astrostatistics or computational astrophysics we encourage you to apply.
You will join the vibrant high energy astrophysics group at API, and can expect to collaborate with our colleagues in the Gravitation and Astroparticle Physics (GRAPPA) Institute. Two postdoctoral researchers will eventually be hired within the AEONS team, with broad goals of quantifying the robustness of PPM and embedding PPM in the wider multi-messenger and nuclear physics context. There is flexibility in how this works in practice, and applicants with interests in either or both areas are welcome. You will work closely with the PhD students on the team, and will have the opportunity to supervise Bachelor and Masters student research projects. You will also be encouraged to pursue your own research lines (please highlight any synergies of existing projects with AEONS in your application).
Applicants should have a PhD related to astrophysics and a track record that is relevant to the goals of the AEONS project. The appointment is for 3 years, to start in Fall 2020 (negotiable). Applications should be submitted electronically via the URL provided (there is an "Apply now" button at the bottom of that page). To apply, please submit a single PDF containing a cover letter, CV, publication list and a brief statement of your research experience, skills and goals. Please highlight anything that is particularly relevant to the AEONS project area. You should also provide names and email addresses for 3 people who can be contacted to provide a letter of reference in the event that your application is shortlisted. The closing date for receipt of applications is February 28, 2020.
Included Benefits:
The salary, depending on relevant experience before the beginning of the employment contract, will be 2.709 to 4.274 EUR (scale 10) gross per month, based on fulltime (38 hours a week), exclusive 8 % holiday allowance and 8.3% end-of-year bonus. A favorable tax agreement, the "30% ruling", may apply to non-Dutch applicants. The Collective Labour Agreement (CAO) of Dutch Universities is applicable.
The UvA is an equal-opportunity employer. We prioritise diversity and are committed to creating an inclusive environment for everyone. We value a spirit of enquiry and perseverance, provide the space to keep asking questions, and promote a culture of curiosity and creativity. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The High Energy Physics, Cosmology and Astrophysics Theory (HEPCAT) group in the Department of Mathematics and Applied Mathematics at the University of Cape Town (UCT) is offering a SARChI in Physical Cosmology postdoctoral fellowship starting in 2020 with Prof. Amanda Weltman.
The position is funded by the South African Research Chairs Initiative (SARChI) of the National Research Foundation. The research priorities of this position are on the science of the HIRAX experiment and the MeerKAT telescope, specifically cosmological parameter estimations with BAOs, understanding Fast Radio Bursts (FRBs) and the cosmological implications of FRBs and using machine learning in astrophysics.
FRB science is gaining increasing attention in the field of cosmology as it aims to synergise observable quantities with multi-wavelength observations in order to exploit them as unique probes of cosmology. We particularly welcome applications from candidates with expertise in one or more of the priority science areas: FRBs, using FRBs/pulsars to probe the interstellar/intergalactic medium, studies of the circumgalactic medium, studies of cosmic baryons and baryonic feedback processes in galaxies.

2.12. PhD position in quantum cosmology and quantum gravity, Sheffield, UK ------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=16949
Deadline: 2020-02-23 Location: Sheffield, UK
Additional Information: https://www.sheffield.ac.uk/maths/prospectivepg/phd/projects Contact: s.c.gielen[AT]sheffield.ac.uk
One of the most important questions in fundamental science concerns the beginning of the Universe. In classical general relativity, this beginning is described by the Big Bang singularity, but we expect this picture to be different in quantum gravity. Quantum gravity could indeed influence the initial conditions for the Universe and thus our understanding of fundamental cosmology.
In studying the impact of quantum gravity on cosmology, one often studies symmetry-reduced models in which the Universe is exactly homogeneous and isotropic, with small linear perturbations added on top. It is often not clear whether this is a valid approximation to the full dynamics, which is complicated and nonlinear.
In this project we want to assess the impact of nonlinearities in quantum cosmology and quantum gravity on the effective description on large scales. The approximation of a homogeneous universe should fundamentally arise from an averaging over the physics at smaller scales. This becomes particularly pertinent in discrete approaches to quantum gravity in which a macroscopic universe arises from a large number of "spacetime quanta".
We will extend the linearised perturbation theory which has been well-studied in quantum cosmology to nonlinear order, and use coarse graining techniques in quantum gravity and quantum cosmology to define a notion of quantum averaging for the cosmological setting. The latter will require developing numerical tools together with some analytical work. We will work within the group field theory approach to quantum gravity and neighbouring fields, such as loop quantum gravity and loop quantum cosmology.
The PhD position is fully funded for 3.5 years including tuition fees and stipend at the Research Council rate (which is GBP 15k in 2019/20).
The studentship can cover a UK or EU student.
Informal enquiries regarding the project and any of its practical aspects are encouraged. If you are interested, please contact the proposed supervisor, Dr Steffen Gielen. Full applications can only be sent to the University of Sheffield, not directly per email. Applications received by 23rd Feb 2020 will receive full consideration.

3.5. Passing of Frank Estabrook ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2020/01/21/passing-of-frank-estabrook/
Additional Information:
With deep sadness we report the passing of our friend and colleague Frank B. Estabrook on October 16, 2019.
Frank was born in Boise, Idaho in 1922. He received a Ph. D. from Caltech in 1950. He came to NASA's Jet Propulsion Laboratory in 1960, following appointments as a professor at Miami University and as a physicist for North American Aviation and the US Army Office of Ordinance Research. Frank brought to JPL a deep understanding of, and a love for, Einstein's general relativity theory. In the mid to late 1960s, when few thought relativity relevant to anything practical, he understood that rapidly advancing technology would make relativity's effects observable in JPL spacecraft tracking and in planetary orbits, and he played a lead role in inspiring his JPL colleagues to incorporate relativity into their work.
At JPL Frank achieved an international reputation for his own work in general relativity, differential geometry, soliton theory, and gravitational waves. With Hugo Wahlquist he reformulated Einstein's general relativity equations into a "dyadic" form that is closely tied to physical measurements, and used this reformulation to gain new insights into Einstein's theory. For the Caltech relativity group led by Kip Thorne, he was a valuable source of mathematical inspiration and advice from the 1960s to the 2000s.
On a more practical side, with Hugo Wahlquist he derived the exact response of spacecraft Doppler tracking (electromagnetically-tracked separated test masses) to gravitational waves and thus how Doppler tracking could be used as a detector in the low-frequency band. The Estabrook-Wahlquist response function is also central to the analysis of very-low-frequency pulsar-timing gravitational wave searches, and it is a foundation for deducing the response of the ultra-sensitive LISA (Laser Interferometer Space Antenna) detector to gravitational waves. Frank was co-inventor of "time delay interferometry", a crucial enabling technology for LISA.
Frank's theoretical work on detector response, and his analysis of noise and sensitivity, provided the scientific impetus for technical improvements in NASA's Deep Space Network, leading to ~1000-fold improvement in Doppler tracking sensitivity between 1980-2000. He was a member of the Galileo radio science team (Principal Investigator for its gravitational wave experiment) and a member of the LISA Mission Definition Team. He lectured in general relativity and applied mathematics at Caltech, served on several NASA advisory committees, and was on the editorial board of the Journal of Mathematical Physics.
Frank had extensive scientific interests. In addition to his general relativity and mathematical physics work he was, for example, the first to propose deep sea drilling into the earth's mantle. He was generous with his time and ideas. On a personal note, he was a man of broad classical culture and a lover of music, especially opera. A quick wit and elegant spirit, he was beloved by his friends and colleagues.

Dear Colleagues,
I hope you would agree that the present status of relativistic mass in spacetime physics should not be silently tolerated.
On the one hand, the physics community is divided - some firmly reject the concept of relativistic mass (e.g., in papers entitled "The Virus of Relativistic Mass in the Year of Physics"), whereas others continue to regard it as an integral part of spacetime physics including in books published last year.
On the other hand, both mass and relativistic mass appear to be equally supported by the experimental evidence - since mass is defined as the measure of the resistance a particle offers to its acceleration (which is the accepted definition based on the experimental evidence) and since it is also an experimental fact that a particle's resistance to its acceleration increases indefinitely (in a given reference frame) as the particle's velocity approaches the speed of light (in the same reference frame), it follows that the particle's mass increases when its velocity increases. Therefore the concept of relativistic mass (like the concept of mass) reflects an experimental fact.
If you are interested in contributing to a volume on relativistic mass, please reply to this Call and also indicate if you would like to serve as an editor or co-editor of the volume.
To try to reach a common understanding of relativistic mass, it was suggested by colleagues to include a special session on relativistic mass in the program of the Sixth Spacetime Conference (see Call for Papers): http://www.minkowskiinstitute.org/conferences/2020/
