abstract
Searches for gravitational-wave bursts have often focused on the loudest event(s) in searching for detections and in determining upper limits on astrophysical populations. Typical upper limits have been reported on event rates and event amplitudes which can then be translated into constraints on astrophysical populations. We describe the mathematical construction of such upper limits.

Search for dynamical black hole captures with Gaussian mixture modelling
A Gaussian mixture model enhanced search in LVK O3 data improves sensitivity to dynamical black hole captures and sets a 90% upper limit of 0.15 Gpc^-3 yr^-1, with no new detections.
