Resum:
The global gravitational-wave detector network currently consists of four interferometers: LIGO Hanford and Livingston, Virgo and KAGRA; the commissioning of LIGO India is also well underway. As the network continues to expand, it is increasingly important to understand the performance of existing gravitational-wave analysis pipelines across different detector configurations. My PhD focused on the multi-detector performance of BayesWave, a trans-dimensional Bayesian analysis pipeline, for the detection and characterization of minimally modelled gravitational-wave bursts. In this talk, I will present three aspects of BayesWave performance: (i) impact of noise-transients (glitches) on burst detection efficiency during the third LIGO-Virgo-KAGRA observing run, (ii) prospects for characterizing gravitational-wave burst tensor polarizations, and (iii) a dedicated-frequency framework for detecting gravitational-wave signatures in core-collapse supernovae.
