PAX IX Workshop at King’s College London, July 23-25 2024 The 9th Physics and Astrophysics at the eXtreme workshop (PAX IX) will be held at King’s College London from 23–25 July 2024. Sessions will take place in central London, at the historic Bush House general auditorium. The goal of this workshop is to explore how the ongoing and upcoming observations of gravitational and electromagnetic waves can help us understand physics at the extreme–– strong gravitational fields, dark matter, nuclear physics, cosmology, and multimessenger astrophysics. the participants list is capped at 100. Please register by the 1st of May 2024 using this link.

Hot-Wiring the Transient Universe VII, May 13-17, 2024, Toronto Hotwiring VII will be hosted by the Dunlap Institute at the University of Toronto, May 13-17 2024. Please come join us to build the future of time-domain astrophysics. This will be a WORKshop, and will have a mix of talks, hack sessions, designing new instruments, and building big robots to look at the sky! Workshop Website

EDSU-Tools 2024 – Exploring the Dark Side of the Univers-Tools , June 2-7, 2024 The EDSU-Tools 2024 conference will be held in island of Noirmoutier (France) from 2nd to 7th of June 2024. The Exploring the Dark Side of the Universe Tools 2024 is a follow-up of World Summit EDSU conferences held in Guadeloupe island (EDSU2018 and EDSU2020) and La Reunion island (EDSU2022). EDSU conferences are among the major venues of interaction between cosmologists and particle and astroparticle physicists. The main goal is to discuss progress and future directions related to outstanding issues, both in Cosmology and in Particle Physics. Conference Website

Dawn VII meeting, June 12-13, 2024 at UBC in Vancouver This discussion-based workshop will focus on planning for upgrades to the LIGO detectors (in the 2030-2035 timeframe) and the next-generation Cosmic Explorer detectors, in the context of a global network of future ground-based detectors. This meeting should engage a broad representation of our global community to place plans for new detectors in the context of multi-messenger astrophysics, cosmology, nuclear physics, and astronomy. In order to help us plan, please let us know if you are interested in attending Dawn VII.

New Frontiers in Strong Gravity, July 7-19 2024, Benasque The third installment of the two-week workshop “New frontiers in strong gravity” will take place in Benasque, Spain from Jul 07–19, 2024. The registration will open in Spring 2024. The highly nonlinear, strong-field regime of gravity holds the key to address long-standing puzzles in modern physics. These range from theoretical questions concerning the nature of gravity, the quest for a consistent theory of quantum gravity and resulting modifications to general relativity, to new insights into nuclear matter under extreme conditions in the context of neutron star and multi-messenger astronomy.
