Youngst@rs - Lost in Translation: The Languages of Gravitational Waves (online) --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=30525 Starting: 2026-01-19 to 2026-01-21 Location: Online Additional Information: https://indico.mitp.uni-mainz.de/event/464/overview Contact: usseglio[AT]ihes.fr In recent years, the modelling of gravitational wave sources has become a cornerstone of theoretical and numerical relativity. Multiple communities - working with distinct formalisms such as Self-Force, Effective One Body (EOB), Effective Field Theory (EFT) and post-Newtonian approximations - have developed powerful tools to describe the two-body problem with increasing precision. Each of these approaches is advanced enough to come with its own set of language, notation, conceptual framework, and computational tools. The workshop aims to bridge this gap and bring these communities closer together. This will be done by providing a mix of beginner friendly lectures, hands on coding sessions, plenary overviews together with state of the art research talks for each of the fields. In particular, there will be three type of sessions: * Plenary Talks: Delivered by senior experts, providing an overview of the approach, its history, strengths, and current challenges, especially those that might benefit from dialogue with other methods; * Pedagogical Lectures: first a theoretical introduction to the key concepts, notation, and logic of the framework, followed by a practical session, which is aimed at demonstrating how to compute a simple observable using available software or symbolic tools; * Early Career Scientist Presentations: 30 minutes talks by junior researchers (PhD students and junior postdocs) showing how they have used the techniques described in the lectures to obtain novel results. Throughout the lectures, a central objective will be to illustrate, within each formalism, the computation of the radiated flux, guiding participants step by step through the derivation and evaluation of this key observable. The Workshop will also allot a considerable amount of time to Q and A sessions. This time will have a crucial importance, given the pedagogical nature of the Workshop. To encourage active participation, especially from younger researchers who may feel uncomfortable asking questions in public, a shared Google document where attendees can submit questions related to the day's lectures. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.4.

Submissions for contributed talks and posters are open now! The link for subscription is provided on the conference website. This conference aims to bring together disparate communities in quantum gravity and quantum information to discuss common foundational concepts, which are defined and employed in different ways across fields. Central topics will include the notions of observers and causality, but the scope extends to related ideas such as measurements, quantum reference frames, quantum groups, and more. We will address questions such as: - What structures are required to define observers in quantum gravity? - What is the relation among the notions of observers, observables, and measurements? - Which features of causal structure are genuinely new in quantum gravity compared to classical spacetime? - Which other fundamental concepts should be examined to help build a shared conceptual language?

CosmoVerse@Bilbao 2026, Bilbao, Spain --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/01/27/cosmoversebilbao-2026/ Starting: 2026-09-15 to 2026-09-18 Location: Bilbao, Spain Additional Information: https://indico.ific.uv.es/event/8160/page/342-overview Contact: cosmoverse.cost[AT]gmail.com Our understanding of the Universe is at a turning point with the predictions of the standard cosmological model and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. The question of cosmological tensions can be confronted in a number of ways. Firstly, survey data needs to be further analyzed for potential systematic uncertainties or biases. Secondly, there have been numerous advances in approaches to data analysis and statistics, some of which provide less dependence on cosmological models to make cosmological parameter estimates. Lastly, there are a plethora of new proposals from fundamental physics which range from novel neutrino physics to dark energy proposals (and others) which may contribute to a solution to the cosmological tensions problem. These represent the three research themes through which cosmological tensions will either be alleviated or resolved. Main topics * Observational cosmology and Systematics (cross-correlation of data, systematic effects) * Data analysis (astrostatistics; data science in astronomy; Bayesian analysis; machine learning and artificial intelligence) * Fundamental Physics (challenge of the cosmological hypothesis, dark energy and modified gravity, neutrino physics, dark energy, and dark matter interaction) Invited Talks Tessa Baker (Institute of Cosmology and Gravitation, University of Portsmouth, UK) Stefano Casertano (Space Telescope Science Institute, USA) Jens Chluba (Jodrell Bank Centre for Astrophysics, University of Manchester, UK) Willem Elbers (Institute for Computational Cosmology, Durham University, UK) Martina Gerbino (University of Ferrara, Italy) Valeria Pettorino (European Space Agency/ESTEC, The Netherlands) Jesus Torrado (Institute for the Structure of Matter (IEM-CSIC), Spain) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.15.

In this cycle, the prize will be awarded on a calendar year basis for 2025. Theses should have been accepted by the relevant institution between January 1, 2025 and 31 December 31, 2025. A committee selected from the gravitational-wave community will evaluate the nominations and select the winner. The selection committee will make all determinations about eligibility. Nominations should be submitted by February 28, 2026. The nomination package consists of (i) the thesis, (ii) a letter of nomination from the thesis advisor, (iii) a supporting letter from another scientist familiar with the work, and (iv) a single-page abstract of the thesis written by the nominee. The nomination and supporting letters should describe the importance and novelty of the research and the student's particular contribution. Because the large number of submissions imposes a significant burden on the jury, we request that each advisor submit a single nomination, and that they consider whether the thesis is indeed internationally competitive. Electronic submissions are strongly preferred, with the thesis, abstract and the letters in separate pdf files (four files in total). Electronic copies of the nomination materials should be sent to gwic-braccini-prize@phys.ethz.ch. Please provide also a contact email address and the current institution of the nominee in the nomination letter. All submissions will be acknowledged once complete; if such an acknowledgement is not received, or for any other question, please contact gwic-braccini-prize[AT]phys.ethz.ch.
