To be held in person at the INFN Galileo Galilei Institute (GGI) on 17-21 April, 2023.

Motivated by the recent breakthroughs in gravitational-wave (GW) astronomy and in the imaging of black holes (BHs), the last few years have witnessed a growing interest in exploring the phenomenology of BHs, compact objects, and horizonless micro-states which emerge in the ‘fuzzball’ proposal in string theory. Semi-analytical, fully numerical techniques and, more recently, exact methods from gauge theory and 2d CFT have been developed by different communities to study the linear response to perturbations of BHs and compact objects, their multipolar structure, tidal deformation properties and absorption coefficients that are crucial to model the GW signal expected from the merger of these objects and discriminate signatures of new physics at the horizon scale.

We are organizing the second edition of a workshop on these topics, with the goal of bringing together scientists from different communities, backgrounds and expertise, to stimulate interdisciplinary interactions between and cross-fertilisation of ideas and techniques as diverse as gauge theories, 2d CFT, BH and GW phenomenology, string theory, and advanced numerical techniques.

We aim to have only two talks per day and devote most of the time to informal discussions and to explore possible collaborations.

The GGI provides the ideal environment for a fruitful and relaxed workshop, also providing office spaces for the participants. For this reason, the number of participants is limited and we suggest applying at your earliest convenience through the workshop webpage.
