Towards a Non-singular Paradigm of Black Hole Physics

Trieste 11-15 November 2024

The study of alternatives to black holes is receiving increasing attention both due to the necessity of going beyond general relativity to describe the interior of black holes, and due to advances in observational capabilities. 

Despite the increasing amount of effort in the field, there are still substantial challenges to be addressed in order to identify and study physically well-motivated classes of non-singular black holes. 

From a foundational point of view, known models of non-singular black holes generally display unstable behavior, while their formation mechanism is still largely unknown, thus raising questions about their viability as alternatives to singular black holes. 

From the observational side, existing analyses of the signatures of different models of non-singular black holes are partial, either due to simplifying assumptions (absence of rotation, absence of backreaction, ...) or due to not including an adequate description of the complex astrophysical processes taking place around these objects (in particular, accretion disk physics). 

The goal of this IFPU program is to bring together experts working on these aspects to push this research area forward, in particular promoting the convergence of different research programs and the identification of central open issues. Every day will be devoted to one of the issues discussed above, as well as their interplay.
