Power Spectral Density Uncertainty and Gravitational-Wave Parameter Estimation

Institute for Pure & Applied Mathematics (IPAM) via YouTube

Overview

Explore the impact of power spectral density uncertainty on gravitational-wave parameter estimation in this 46-minute conference talk. Delve into techniques for estimating power spectral density, methods for incorporating uncertainty into parameter estimation frameworks, and the potential systematic biases that can arise when ignoring this uncertainty. Examine the offsource and onsource methods, alternative parametrizations, and approaches like marginalization and important sampling. Gain insights into the context of power spectral density uncertainty within other sources of systematic error in gravitational wave astronomy. Understand the implications for characterizing compact binary coalescences and combining multiple gravitational wave events.
