Query: Exploring Features in the Binary Black Hole Population   Vamana is a mixture model framework that infers the astrophysical
distribution of chirp mass, mass ratio, and spin component aligned with the
orbital angular momentum for the binary black hole population. We extend the
mixing components in this framework to also model the redshift evolution of
merger rate and report all the major one and two-dimensional features in the
Binary Black Hole population using the 69 gravitational wave signals detected
with a false alarm rate $<1\mathrm{yr}^{-1}$ in the third Gravitational-Wave
Transient Catalog (GWTC)-3. Endorsing our previous report and a corroborating
recent report from LIGO Scientific, Virgo, and KAGRA Collaborations, we observe
the chirp mass distribution has multiple peaks and a lack of mergers with chirp
masses $10 \textrm{--} 12M_\odot$. In addition, we observe aligned spins show
mass dependence with heavier binaries exhibiting larger spins, mass ratio shows
a dependence on the chirp mass but not on the aligned spin, and the redshift
evolution of the merger rate for the peaks in the mass distribution is
disparate. These features possibly reflect the astrophysics associated with the
binary black hole formation channels. However, additional observations are
needed to improve our limited confidence in them.
