Title: Sky Localization Accuracy and Electromagnetic Follow-up with Future Gravitational-Wave Observatories

Speaker: Shreya Anand, University of Maryland

Abstract: Future generations of ground-based gravitational-wave (GW) observatories promise a wealth of compact binary source detections in the local and distant universe, which would otherwise have remained invisible to us. Combined with electromagnetic telescopes, future GW detectors could make electromagnetic counterpart matching, host galaxy identification, and cosmology possible for a greater fraction of GW sources than with our present detector network. However, achieving these science goals is contingent upon the localization accuracy of the detection. I will present a preliminary investigation into the potential of third generation (3G) GW detectors from the standpoint of localization. Specifically, my focus will be on how statistical and systematic uncertainties in the gravitational-wave signal arrival time and phase could affect source localization as a function of the distance to binary neutron star and binary black hole sources. I will also briefly discuss implications for science goals and potential science requirements for future GW detectors.
