ParSpec: a data-analysis framework for black-hole spectroscopy with multiple events
Andrea Maselli, Paolo Pani,Leonardo Gualtieri,Emanuele Berti
Black-hole spectroscopy is arguably the most promising tool to test gravity in extreme regimes and to probe the ultimate nature of black holes with unparalleled precision. In this talk I will present an observable-based approach based on Parametrized
Ringdown Spin Expansion Coefficients (ParSpec), to parametrize beyond-GR deviations from the standard QNM ringdown of a Kerr BH in Einstein’s theory. I will show how this method can be used to constrain a large number of beyond-Kerr ringdowns, and to set bounds on the fundamental parameters which characterize possible GR modifications.
