Dent, ThomasCalderón Bustillo, JuanVilla Ortega, Verónica2024-11-142024-11-142024https://hdl.handle.net/10347/37707The first detection of a binary neutron star coalescence with an electromagnetic counterpart in August 2017 marked the beginning of gravitational-wave multi-messenger astronomy. This thesis explores the follow-up of gravitational wave events from compact binary coalescences, focusing on obtaining rapid and accurate estimations of source parameters essential for enabling multi-messenger observation campaigns. The work details the development and implementation of two algorithms capable of estimating the properties of the source, including the probabilities of containing neutron star or black hole components, as well as accurate estimates of intrinsic masses and spins for low-mass binary systems.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/gravitational wavePyCBC Liveastrophysicalastronomy210105 Gravitacióndoctoral thesisopen access
