Dedicated-frequency analysis of gravitational-wave bursts from core-collapse supernovae

Abstract

Abstract Gravitational waves (GWs) emitted during a core-collapse supernova exhibit characteristic frequency features that encode information about the underlying physical processes leading up to the explosion. The dedicated-frequency framework is a hierarchical pipeline for following up GW burst detection candidates via bandpass analyses, designed to facilitate the detection of frequency-specific GW signatures. The applications of the dedicated-frequency framework are demonstrated using two separate case studies: a low-frequency (LF) and a high-frequency (HF) analysis. A successful detection with the LF analysis,..
