Accurate modeling and mitigation of overlapping signals and glitches in gravitational wave data
ORAL
Abstract
Transient noise artifacts or “glitches” in LIGO detector data challenge parameter estimation of gravitational wave signals. We present a method that concurrently fits for glitches and gravitational waves by separating them into a template and a wavelet model. We show the efficacy of this method on black hole and neutron star binaries atop a range of glitch types.
