A template-free approach for waveform extraction of gravitational wave events
Scientific Reports, 2021 We develop a general data-driven and template-free method for the extraction of event waveforms in the presence of background noise. Recent gravitational-wave observations provide one of the significant scientific areas requiring data analysis and ...

Extracting the orbital axis from gravitational waves of precessing binary systems
, 2018 We present a new method for extracting the instantaneous orbital axis only from gravitational wave strains of precessing binary systems observed from a particular observer direction. This method enables us to reconstruct the co-precessing frame waveforms
