Cosmic Explorer Symposium and Physics and Astrophysics at the eXtreme workshop (PAX-X) at UIUC from 30 June – 3 July 2025

The 10th Physics and Astrophysics at the eXtreme workshop (PAX X) and the 3rd Cosmic Explorer Symposium will be held jointly at the University of Illinois Urbana-Champaign from 30 June – 3 July 2025.

The Cosmic Explorer Symposium will bring together the community to discuss important aspects of the design and operations of the Cosmic Explorer gravitational-wave observatories, covering both observational and instrument science.
The PAX-X workshop will 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.

Panels will be organized around a small number of presentations to identify important areas for research and foster discussions and community feedback.

Registration will open shortly.

Ten Years to LISA: New Challenges and Opportunities in Multimessenger/Multiband Science, April 1-3, 2025, hybrid

The conference website for Ten Years to LISA: New Challenges and Opportunities in Multimessenger/Multiband Science is now online.
This is a hybrid meeting, meaning participation can be virtual or in-Person. Dates: April 1-3, 2025. In-Person Location: von Karman Auditorium, Jet Propulsion Laboratory, Pasadena, CA

Conference Overview: Motivation and Format

For the purpose of this Overview, “multimessenger astronomy” stands for “multimessenger including gravitational waves”, and “multiband” means “multiple gravitational-wave bands”. Multimessenger astronomy, in this sense, began with a bang with the LIGO-Virgo detection of GWs from the merger of two neutron stars, GW170817, an event that was soon observed in most EM bands. While there was an expectation in the field that NS mergers powered some short gamma-ray bursts (sGRBs) and models of their subsequent radioactive decay (kilonova) existed, confirmation of these theories occurred only from GW170817. Details of these events, like the delay between the GW and GRB signals and the GRB strength, however, led to new insights into their pre-merger environments and the dependence on viewing angle of the jet’s appearance.

Astrophysicists’ predictions of the EM signals that will accompany LISA (Laser Interferometer Space Antenna) events may be even less advanced than sGRB models prior to GW170817 and share a lack of confirming evidence. This conference is premised on the viewpoint that this relative ignorance represents an opportunity, or, really, several opportunities. There is important work to be done i) using past and upcoming observations (both EM and GW) to constrain event rates and search for the signatures of LISA-type events before LISA turns on; and ii) using astrophysical models to predict the multimessenger and multiband signals that will accompany LISA signals.

We have about ten years to work on this before LISA and Nature start to give us some of the answers. It is our belief that such work done before LISA starts taking data will almost surely help us maximize the science we extract. (And we expect that will be true even if most of our predictions are not ultimately borne out by observations.)

With the above as motivation, this Conference will give overviews of the sorts of EM & GW observations that we expect to be made over the next 10+ years and how they relate to LISA. And it will suggest LISA multimessenger/multiband science investigations that could be started now. Our main goal is to help stimulate new, important work in these areas.

The format for the conference is as follows. We have divided our subject into eight topics. Over the course of the three-day conference, there will be eight sessions: one devoted to each topic. For each session, we have found a topical expert who has agreed to chair that session. The Session Chairs will build their sessions using some combination of invited talks and talks contributed via this website. It will be up to each Session Chair to construct their session as they think best.

This a hybrid conference, meaning participation can be either in-person or online. There is zero registration fee for either in-person or remote attendance. However, we recommend that you attend in person, if you can, to benefit from the side discussions that are important part of any conference. We plan to limit talks to about six hours per day, to leave plenty of time for such side discussions.

Important Dates:

  • Monday, December 23, 2025 – Registration open
  • Tuesday, February 4, 2025 – Deadline for abstract submission for presentations and posters
  • Monday, February 24, 2025 – Registration closes for attendees from these Designated Countries who are attending in person
  • Monday, March 10, 2025 – Registration closes

Geometric Foundations of Gravity 2025, June 30 – July 4 in Tatu

is a conference dedicated to the various approaches to gravity that venture beyond the basic formalism of general relativity, i.e., the description in terms of a massless metric field in Riemannian geometry derived from the Einstein-Hilbert action. The topics will range from the foundational issues to the applications in cosmology, gravitational waves, black holes, and other objects.

The meeting will take place on June 30 – July 4, 2025 in Tartu, Estonia. It is a continuation of a series of earlier conferences and workshops on the related subjects.

The topics under discussion include for instance:

  • Extensions of general relativity (metric-affine gravity, Poincare gauge gravity, scalar/vector/tensor gravity, teleparallel gravity, massive gravity, bi-metric gravity, etc)
  • Phenomenology of extended gravity (black holes, ordinary/neutron/boson/grava stars, gravitational waves, cosmology, dark energy, dark matter, galaxies, early universe etc)
  • Beyond Lorentzian geometry in classical and quantum gravity (doubly/deformed relativity, standard model extension, Hamilton geometry, Finsler geometry, etc).

The last day of the conference is planned for hands on tutorial workshops on using computer algebra in gravity theory calculations, focussing on free specialized software packages Cadabra and SymPy (tensor).

The conference is organized by the gravity research group at the Laboratory of Theoretical Physics, Institute of Physics, University of Tartu.

Unlocking Gravity Through Computation, December 9-11, 2024 in Prague

General relativity is a beautiful, but highly complex theory in terms of its field content, invariant structure and the nature of its dynamical equations. Describing gravitational phenomena beyond a weak-field regime and in the absence of global symmetries requires refined computational methods. Progress in understanding black hole properties, binary systems, the early universe, and astrophysical environments depends critically on further developing our computational tool box.

Unlocking Gravity Through Computation will bring together gravity researchers from different backgrounds. We are delighted to be hosting a broad range of keynote speakers working at the forefront of developing and applying numerical approximation and simulation techniques, as well as new analytical methods. We aim for a constructive and interactive meeting, including discussions on the future challenges and opportunities for computation in classical and quantum gravity. We invite the submission of abstracts for contributed talks and posters and encourage especially junior researchers to participate.

Testing Gravity 2025, January 29 – February 1, 2025, Vancouver

Testing Gravity 2025 will be the 5th Testing Gravity conference hosted by Simon Fraser University. Held at the SFU Harbour Centre January 29 - February 1, 2025, it will bring together leading experts on various ways of testing laws of gravity. Testing Gravity remains a topical theme because of the unexplained nature of dark matter and dark energy and the long-standing failure to reconcile gravity with quantum physics. Like the previous meetings, TG2025 will feature latest updates from gravitational wave and astrophysical observatories, lab-based experiments, as well as discussions of recent theoretical advances. The conference aims to provide theorists working on extensions of General Relativity with a realistic perspective on what aspects of their theories can be tested. On the other hand, the experimentalists and observers will get a chance to learn about new ideas that their experiments can test.

Wednesday, January 29th, will feature a school with five review lectures given by some of the invited speakers providing background into the key topics covered by the conference. The main conference, January 30 – February 1, will include invited and contributed talks, and a poster session.
