Search for Gravitational Wave Signals Associated with Gamma-Ray Bursts during LIGO's Second Observing Run
Year: 2020
Type: dissertation
Abstract: The advanced LIGO and Virgo detectors have recently ushered in the\n\nage of gravitational wave astronomy. In this dissertation we briefly review how\n\ngravitational waves arise from general relativity, how they are produced, and how\n\nthey are detected with LIGO. We also review the connection between gravitational\n\nwaves and gamma-ray bursts, and review a method used to search for gravitational\n\nwaves from gamma-ray triggers. A search for gravitational wave signals associated\n\nwith gamma-ray bursts during the second observing run of advanced LIGO and\n\nVirgo is presented. Of the 98 bursts considered, no significant signals were found\n\nexcept for GW170817 which was found with a p-value of 3.1 × 10 −4 . We report\n\nlower bounds on the distance to these gamma-ray bursts (GRBs), assuming various\n\nsignal morphologies. We also describe the physical environment monitor system\n\nused at the LIGO observatories and present a new wide-band RF monitor for that\n\nsystem.\n\nThis dissertation contains previously published co-authored material.
