Abstract      = {We present a new, simulation-based inference method to compute the angular
power spectrum of the distribution of foreground gravitational-wave transient
events. As a first application of this method, we use the binary black hole
mergers observed during the LIGO, Virgo, and KAGRA third observation run to
test the spatial distribution of these sources. We find no evidence for
anisotropy in their angular distribution. We discuss further applications of
this method to investigate other gravitational-wave source populations and
their correlations to the cosmological large-scale structure.},
