While most detected binaries to date are consistent with circular inspirals, there is mounting evidence that eccentricity may already be present in current events, with claims ranging from high-mass and low-mass black hole binaries to neutron star-black hole systems. Understanding, modeling, and interpreting eccentric sources is both timely and urgent. The workshop will bring together experts in theory, numerical relativity, data analysis, and astrophysics, as well as early-career researchers entering these fields. We aim to create a collaborative environment where participants can share results, exchange ideas, and identify the next key steps. The core program of the workshop will take place on September 1st-4th, 2026 at the Corfu Summer Institute, which is located in Mon Repos park, a short walk from Corfu town. In addition, the conference center will also be open and available to us on September 5th-6th; attendees can take it as an opportunity to work in small groups while enjoying Corfu's seaside, beaches, and great food. The workshop will have a conference fee of 350 Euros (250 Euros for students) covering coffee breaks, lunches, welcome reception, conference dinner, and two excursions (hopefully on a boat). While we are unable to provide travel support, accommodation in Corfu in September is relatively inexpensive (but the beaches are still great!). The workshop will be in person without remote options. Interested participants should register on the conference website by June 1st, 2026. Depending on the number of people registering, participants might need to be selected. We will be in touch soon after the registration deadline. When registering, please indicate possible discussion topics you would like to contribute to. Looking forward to seeing you in Corfu!

They will learn how specific experimental setups can be used to test the theoretical predictions. This education equips the participants with the skills to bridge the gap between theory and experiment in the field of the interplay between quantum systems and classical and quantum gravity research in the future. This is the second of a series of Training Schools organised by the European COST Action CA23130 - BridgeQG: Bridging high and low energies in search of quantum gravity. While the focus of the first training school was on the high-energy aspects of the BridgeQG research topics, the focus of this training school will be on the low-energy aspects. A third school will cover the combination of the two branches. The school consists of four main lectures, which are accompanied by tutorial classes. In addition there will be an introductory short lecture on quantum gravity phenomenology, and a concluding short lecture. Lecture notes will be published after the school. Lecturers and topics (Final titles of the lectures will be announced soon) - Caslav Brukner: quantum clock and quantum reference frames for quantum gravity - Rainer Kaltenbaek: tests of quantum physics is beyond Earth, using satellites and space experiments to probe entanglement, superposition, and the limits of quantum mechanics in macroscopic bodies - Sofia Qvarfort (TBC): metrology of the gravitational field with quantum systems,metrology with opto-mechanical systems,measuring gravitational waves - Benjamin Stickler: levitated systems, optomechanics, quantum/classical control of motion using light, such as cooling, and applications of levitated systems for fundamental tests - Simone Manti: testing quantum gravity with underground experiments +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.12. The Interplay of Magnetic Fields, Nuclear Physics, and Nucleosynthesis in Neutron-Star Mergers and Supernovae, Trento, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/02/25/the-interplay-of-magnetic-fi… Starting: 2029-09-21 to 2026-09-25 Location: Trento, Italy Additional Information: https://www.ectstar.eu/workshops/the-interplay-of-magnetic-fields-nuclear-p… Contact: evan.oconnor[AT]astro.su.se We would like to make you aware of an upcoming ECT* workshop on the interplay of magnetic fields, nuclear physics, and nucleosynthesis in neutron-star mergers and supernovae. Registration to open later in the spring. Neutron-star mergers and core-collapse supernovae are among the most promising sites for the synthesis of heavy elements in the universe. These astrophysical phenomena bring together a rich interplay of general relativity, neutrino physics, nuclear reactions, and magneto-hydrodynamics. Among these factors, magnetic fields are increasingly recognized as playing a pivotal role in shaping the dynamics and nucleosynthetic outcomes of these events. Recent observational breakthroughs, from the detection of gravitational waves (e.g., GW170817) with EM counterparts and increasingly detailed supernova spectra, demand a deeper theoretical understanding of how magnetic fields interact with nuclear physics and influence heavy-element nucleosynthesis. At the same time, simulations of these events now routinely include magnetic fields and detailed neutrino transport demonstrating the potential of magneto-rotational supernovae and neutron-star mergers to produce rich nucleosynthesis yields including the heaviest elements produced by the r-process and set the stage for GRB jets. Given all these recent developments we are at a critical moment to advance the field but there is a need for detailed discussions and interactions among nuclear physicists, astrophysicists, and computational modelers to address key open questions and make the most of the available observational datasets and computational resources. This workshop aims to bring these communities together.

In 2015, a black hole binary was detected through gravitational waves. Since it was suggested that the system might consist of primordial black holes, researchers not only in cosmology and gravitation but also in particle physics and astrophysics have increasingly recognised the importance of primordial black holes. As a result, research on primordial black holes has developed rapidly and expanded significantly over the past decade. This workshop is organised to promote international collaboration, foster mutual understanding, and encourage future constructive and cutting-edge joint research. The workshop will bring together researchers conducting cutting-edge research on various aspects of primordial black holes, providing a forum for in-depth discussion and interaction. The first workshop in this series was held at Rikkyo University in March 2023, and the second at Nagoya University in October 2024. This meeting is the third in the series.

The school will take place in Nice this year, on the beautiful Valrose Campus of Universite' Cote d'Azur (see here). It will be held in English. The school will cover the emerging field of gravitational wave detection and of its scientific exploitation. Following their discovery by the LIGO/Virgo collaboration, many other gravitational wave detections are expected at the existing and future gravitational antennas. They will open up a new window of exploration, sometimes unique and sometimes complementary to what other messengers such as electromagnetic radiation (radio, IR, visible, UV, X-rays, gamma rays) and neutrinos can reveal of the physics at work in our Universe. The objective of the school is to provide the students with a solid introduction to most aspects of this interdisciplinary field in accelerated expansion. The School has no online attendance option. All participants are expected to attend in-person. No fee is required to attend the School. The School will provide coffee breaks and lunches to all participants. Dinners, travel and accommodation expenses are not covered. However, accommodation free of charge will be provided by the CROUS at Valrose Campus for up to 50 master and PhD students who request it in the registration form. For more information about this opportunity and the selection, please see the accommodation section on this webpage. Moreover, since the school is labelled by CNRS as "Ecole Thematique", the expenses to attend the school for CNRS employees (staff CNRS people and people with a CNRS term contract [PhD student, Postdoc,...]) will also be covered. Please do not forget to mention in the registration form if that case applies to you! +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.17.

News ============================================== 3.1. In Memoriam: Kenneth Nordtvedt Jr. ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/02/07/in-memoriam-kenneth-nordtved… Additional Information: none I am sad to report the death of Kenneth Nordtvedt Jr, on October 9, 2025 at the age of 86. Along with Robert Dicke, Leonard Schiff, Irwin Shapiro and Joseph Weber, Ken was a pioneer of the resurgence of experimental gravity that began in the 1960s. In three amazing papers in 1968, he parametrized the post-Newtonian point-mass metric of general relativity; showed that, in alternative theories, self-gravitating bodies could violate what we now call the Strong Equivalence Principle, and pointed out that lunar laser ranging could test the effect (today called the Nordtvedt effect). They were a revelation to me as a beginning graduate student in Kip Thorne's group in 1969, inspiring me to generalize his approach using Chandrasekhar's post-Newtonian hydrodynamics. Later, during a 1971 summer workshop on experimental gravity organized by Ken in Bozeman, one of Kip's students named Sandor Kovacs took it upon himself to nag Ken and me incessantly to merge our two approaches into one, even threatening to lock us in a room until we did so. The result was the canonical parametrized post-Newtonian (PPN) framework that became a standard tool for the subject. In July 1969, Apollo astronaut Neil Armstrong deployed the first laser "retroreflector" on the lunar surface, and within a few weeks, lunar laser ranging began in earnest, and continues to the present day, reaching millimeter precision in measuring the Earth-Moon distance. The data has consistently shown no evidence of the Nordtvedt effect, in agreement with GR. As Ken frequently remarked, zero is as good a number as any other (and indeed, null experiments have been a mainstay of fundamental physics). Data on the pulsar in a triple system, J0337+1715, also found no evidence of the Nordtvedt effect, but now in the strong-field regime. Ken and I devised the first "vector-tensor" alternative theory of gravity designed to show how one could get effective violations of Lorentz invariance and "preferred-frame" effects in gravity. Our theory was crude and deeply flawed; later Ken and Ron Hellings produced a better theory. More recent theories such as Einstein-Aether, Horava gravity, TeVeS and others, were built upon the foundation laid by Ken and Ron. In recent years Ken collaborated with Eric Adelberger, Tom Murphy and others to create APOLLO, an improved lunar laser ranging facility at the Apache Point telescope in New Mexico. He continued publishing interesting papers on post-Newtonian theory and tests of gravity into his 70s. Ken got his undergraduate degree at MIT and his PhD under Schiff (in solid-state physics) at Stanford, and had a postdoc as a Junior Fellow at Harvard. But dissatisfied with the lifestyle and politics of the two coasts, Ken accepted a faculty position at Montana State University in Bozeman in 1967. He characterized himself as a Libertarian, and even served a six-year term (1979 - 84) in the Montana State legislature (a part-time job, as in many rural states). In 1986 he was appointed by President Ronald Reagan to serve on the National Science Board, which oversees the NSF. An avid DIY person, he once built from scratch a house as well as an ocean-worthy sailboat, which he sailed to Europe and around the Mediterranean. At MSU, he built a strong gravitational physics group, including over the years Ron Hellings, Sachiko Tsuruta, Bill Kinnersley, Lee Lindblom, Bill Hiscock, Neil Cornish, Nico Yunes, and Hang Yu, and many grad and post-doc alumni with distinguished careers of their own.
