“EFTs, Gravity, and Fluid Dynamics: Progress, Challenges, and Emerging Opportunities Workshop” is an event sponsored by the Physics Department of the University of Illinois at Urbana-Champaign and The Gravity Theory Trust, taking place in Urbana, Illinois on December 16 – 18, 2024 in room 190 of the Engineering Sciences Building.

The purpose of this workshop is to bring together experts in Effective Field Theory (EFT), gravity, and fluid dynamics to foster interdisciplinary collaborations.

Sample topics interfacing EFTs, gravity, and fluid dynamics include:

New insights in gravitational thermodynamics and gravitational EFTs.
Causality constraints on gravitational and hydrodynamic EFTs.
The fluid-gravity correspondence.
Mathematical aspects of well-posed formulations of non-ideal fluid dynamics in general relativity.

There is no registration fee but registration is required. The deadline for registration is October 31, 2024.

Gravitational Wave Background Found in Pulsar Timing Arrays: Implications for Merging Supermassive Black Holes

Coordinators: Luke Kelley, Chiara Mingarelli, and Gabi Sato-Polito 

The recent observation of nanohertz gravitational waves by Pulsar Timing Arrays (PTAs) has opened a new observational window into the universe. Although the origin of the signal has yet to be determined, the measured gravitational-wave background may be produced by a collection of in-spiralling supermassive black holes (SMBHs) or by physics beyond the standard model. The evidence for this background therefore offers unique insights into the astrophysics of SMBHs and potentially new physics. This Rapid Response Workshop will solely focus on the scientific implications for SMBHs of this first PTA detection bringing together experts on both theory and observations.

Fundamental aspects of black holes have been actively studied so far to unravel the mystery of black holes and to achieve new physics like the quantum theory of gravity. Black holes are the simplest astrophysical objects in the Universe as each black hole can be characterized by a few parameters only in general relativity. For this reason, they are regarded as the best sites to probe new physics.

Given the recent developments in observational and theoretical progress in black hole physics, it is important for theoretical physicists to discuss how we can unravel the mysteries of black holes, probe new physics, and test existing theories from both fundamental and observational points of view.

This workshop aims to bring together experts working on astrophysical and fundamental aspects of black holes to share ideas and expertise and to offer introductory talks to learn relevant state-of-the-art knowledge.

Workshop Website

JGRG is the community of researchers in Japan, working on General relativity and Gravitation. JGRG has hosted an annual workshop series under the same title since 1991. The main purpose of the workshop is to provide a venue for exchanging ideas to pursue future trends of research. The workshop covers a wide range of topics related to general relativity and gravitation.

From astrophysics to high-energy physics, from information theory to quantum gravity, black holes have acquired an ever increasing role in fundamental physics, and are now part of the terminology of many important branches of observational, theoretical and mathematical physics.

The Black Holes Workshops gather researchers working on physical and mathematical problems of black holes, both in their classical and quantum aspects, as well as their connections to general relativity and gravitation, string theory, cosmology, and astrophysics, and stimulate the interaction between all these issues.

The seventeenth edition of the Black Holes Workshop celebrates landmark contributions in the history of black holes and gravitation, namely the 50 years of the Hawking radiation, the 50 years of the discovery of the Hulse and Taylor pulsar, and the 75 years of the Gödel solution.

The workshop will take place at the University of Aveiro, in December 19 and 20, 2024. Researchers on black holes in all their aspects are invited to participate. Registration for the event will start on September 16th and end on December 2nd. The deadline to submit abstracts is November 22nd. A limited number of accepted contributions will be selected, taking into account their scientific merit. Submissions of abstracts after the deadline will not be allowed. Please follow the registration instructions.

In this edition there will be no registration fee for participants.
