New Frontiers 2025: past, current and future challenges in Numerical Relativity

In the history of numerical (or computational) general relativity, the “Frontiers” meeting in 1988 at the University of Illinois, Urbana-Champaign (USA), played a pivotal role in establishing numerical relativity as a major topic in computational physics and simulation science. The “New Frontiers” meeting in 2006 at the AEI Potsdam convened following major breakthroughs in numerical simulations of binary systems. The most recent “Frontiers 2022” conference was instrumental in assessing the state-of-the-art and identifying future directions in numerical relativity. The upcoming “New Frontiers 2025: past, current and future challenges in Numerical Relativity” will emphasize the significant theoretical and computational challenges ahead, not only in understanding the observations of gravitational waves and electromagnetic counterparts but also in comprehending the nature of gravity at a more fundamental level. Reflecting on previous problems in theory and computation, and how our community overcame them, may guide us in current and future endeavors. 

Main topics:
o Mathematical foundations
o Numerical methods for the Einstein and the radiation MHD equations
o High performance computing
o Astrophysics (binary mergers, gravitational waves, electromagnetic counterparts,…)
o Beyond current astrophysics and general relativity 

The meeting will take place at the University of the Balearic Islands starting on July 21st and ending on July 25th, 2025. Registration is already open and there is no fee!
