Toward a unified view of agnostic parametrizations for deformed black holes
Manuel Del Piano, Ciro De Simone, Mattia Damia Paciarini +4
A variety of robust and effective descriptions have been devised to extract model-independent information about the fundamental properties of black holes from observational data wh…

Regular Spacetimes in the Effective Metric Description
Mattia Damia Paciarini, MikoÅaj Myszkowski, Francesco Sannino +1
Over the past few decades, significant effort has been directed towards developing various regularized models for compact objects. Recently, a new observable-based parametrization…
