============================================== 1. Conferences ============================================== 1.1. Experimental Tests and Signatures of Modified and Quantum Gravity, Bad Honnef, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2020/08/17/experimental-tests-and-signat...

Two major unsolved questions in fundamental physics are related to the gravity: What is the nature of Dark Matter and Dark Energy, and, what is the theory of quantum gravity? From the theoretical point of view these questions stimulated various fundamental approaches to a theory of quantum gravity, such as string theory, loop quantum gravity, canonical quantum gravity, noncommutative geometry, asymptotic safety and others as well as phenomenological models such as doubly or deformed special relativity and the relative locality framework. Moreover, numerous classical modifications of General Relativity have been suggested such as scalar-tensor theories, f(R)-theories, bi-metric gravity, tensor-vector-scalar gravity or metric affine gravity, Poincare gauge theory, telleparallel gravity, Finsler gravity and many more.
The viability of these alternative or extended theories of gravity has to be tested by comparison of predictions with experimental data. It is important that this comparison is done on all scales from the whole universe, i.e. on cosmological scales, via galaxy-clusters, galaxies, binary systems, black holes, the solar system, satellite experiments, down to laboratory experiments at micrometer and smallest scales, i.e. high energy scales looking for new elementary particles like axions or WIMPs.
This seminar aims for discussing predictions and their comparison with experiments of extended and modified classical and quantum theories of gravity, on all scales. The goal is to identify theories, which are consistent on all scales, and, to identify observables, in which deviations of general relativity or the quantum nature of gravity is most likely to manifest itself.

2.2. Postdoctoral Fellowships in Turkey, Istanbul, Turkey ------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2020/08/11/postdoctoral-fellowships-in-t...
Deadline: 2020-09-15 Location: Istanbul, Turkey
Additional Information: http://cocirc2.org.tr/ Contact: framazanoglu[AT]ku.edu.tr
Short Description: Turkey will host many Cofunded Brain Circulation Scheme (CoCirc2) fellows in the coming years in all areas of research. This is very similar to MSCA fellowships in terms of application procedure, duration and financial benefits, but the host institution has to be in Turkey. If you are a gravitational physicist (especially working on gravitational waves, numerical relativity and/or alternative theories) interested in working with Fethi M Ramazanoglu at Koc University, please read on.
Co-Funded Brain Circulation Scheme (CoCirculation2) is a program managed by the Scientific and Technological Research Council of Turkey (TUBITAK) and funded jointly by TUBITAK and Europe's 7th Framework Programme. The fellowship is quite similar to MSCA Fellowships in structure, but the host has to be in Turkey. It aims to attract qualified researchers from abroad, and will fund around 25 fellows for 24 months . Detailed information can be found at http://cocirc2.org.tr/ - The fellowship is not restricted to any specific research discipline. - Each recipient will receive a monthly living and mobility allowance of 5050 Euros and monthly Research, Training and Networking cost of 800 Euros (note that living expenses in Turkey are considerably lower than the EU average). - There is no restriction on citizenship, please see the website about other eligibility requirements such as research experience. - There is a possibility of up to 6 months of secondments outside Turkey. - This year's applications opened on 4 August 2020, and close on 30 October 2020, but i will hold an internal deadline of September 15 to have time to finalize the proposal. - In my experience, the chances of being awarded this fellowship is considerably higher than obtaining the MSCA Fellowship since the host institute has to be in Turkey.
The application procedure is also very similar to the MSCA Fellowships. Every applicant applies together with a supervisor, and to a specific institution. If you are interested in postdoctoral research on gravitational physics at Koc University, please send a CV with publication list and a short research statement (in summary or full length) to framazanoglu[AT]ku.edu.tr by our internal deadline of September 15. You can find my research interests at http://mysite.ku.edu.tr/framazanoglu/. I will pick one or two of the applicants to finalize proposals to submit. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

============================================== 3. News ============================================== 3.1. Piotr T. Chrusciel, Geometry of black holes ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2020/08/08/piotr-t-chrusciel-geometry-of...
Additional Information: https://global.oup.com/academic/product/geometry-of-black-holes-978019885541...
New textbook
From the publisher's web page:
There exists a large scientific literature on black holes, including many excellent textbooks at various levels. However, most of these steer clear from the mathematical niceties needed to make the theory of black holes a mathematical theory. Those which maintain a high mathematical standard are either focused on specific topics, or skip many details. The objective of this book is to fill this gap and present a detailed, mathematically oriented, extended introduction to the subject.
The book provides a wide background to the current research on all mathematical aspects of the geometry of black hole spacetimes. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The book covers all our current understanding on the physics of the amplification of waves by a medium, including classical effects such as the Cherenkov effect. The main body of the book deals with superradiance in black hole physics, with important applications in astrophysics and particle physics. Each chapter ends with a list of outstanding open problems and future directions. The second edition corrects a number of typos and, most importantly, adds and updates several sections, reflecting the intense activity in the field in the last years. Current bounds on ultralight fields are summarized in a Table, and will be updated online regularly.

Additional Information: https://www.springer.com/gp/livingreviews/relativity
The open-access journal Living Reviews in Relativity has published a new review article on 28 August 2020:
Alberto Zaffaroni, "AdS black holes, holography and localization", Living Rev Relativ 23, 2 (2020) https://doi.org/10.1007/s41114-020-00027-8
Abstract: I review some recent progresses in counting the number of microstates of AdS supersymmetric black holes in dimension equal or greater than four using holography. The counting is obtained by applying localization and matrix model techniques to the dual field theory. I cover in details the case of dyonic AdS4 black holes, corresponding to a twisted compactification of the dual field theory, and I discuss the state of the art for rotating AdS5 black holes.
