title: 2-OGC: Open Gravitational-wave Catalog of binary mergers from analysis of public Advanced LIGO and Virgo data
abstract:
In this talk, I will present the second Open Gravitational-wave Catalog (2-OGC) of compact-binary coalescences, obtained from complete set of public data from Advanced LIGO's first and second ovserving runs and the data from Virgo detector. In this analysis, we improved the detection of compact binary coalescence by accounting for short term PSD variation in defector's noise and instantaneous network sensitivity. We report 14 significant binary black hole mergers with p-astro > 0.5 and a binary neutron star merger GW170817. A comprehensive catalog of all the events, with sub threshold populations of candidates is made available.
