Growing Pains: Understanding and Handling Systematic Errors in Gravitational-Wave Population Analyses

During the first three observing runs of gravitational-wave detectors, we observed nearly 100 signals from compact binary mergers. During the fourth observing run, which is expected to begin later this year, we can anticipate observing hundreds more such systems. This expanding population has and will continue to enable many new insights ranging from stellar astrophysics to cosmology and strong-field tests of general relativity. Most of these measurements rely on combining information from the entire catalog of mergers to constrain the underlying physics. However, the methods used scale poorly with the increasing size of the observed population. In this talk, I will demonstrate that existing analysis methods scale poorly with the scaling with population size and discuss potential solutions to enable gravitational-wave astronomy at scale.
