Guesswork in the gap: the impact of uncertainty in the compact binary population on source classification
Utkarsh Mali, Reed Essick
The nature of the compact objects within the supposed "lower mass gap" remains uncertain. Observations of GW190814 and GW230529 highlight the challenges gravitational waves face in…
Compact Binary Coalescence Sensitivity Estimates with Injection Campaigns during the LIGO-Virgo-KAGRA Collaborations' Fourth Observing Run
Reed Essick, Michael W. Coughlin, Michael Zevin +21
We describe the effort to characterize gravitational-wave searches and detector sensitivity to different types of compact binary coalescences during the LIGO-Virgo-KAGRA Collaborat…
Astrophysical constraints on neutron star -modes with a nonparametric equation of state representation
Sailesh Ranjan Mohanty, Utkarsh Mali, H. C. Das +2
We constrain the fundamental-mode (-mode) oscillation frequencies of nonrotating neutron stars using a phenomenological Gaussian process model for the unknown dense-matter equat…
Striking a Chord with Spectral Sirens: multiple features in the compact binary population correlate with
Utkarsh Mali, Reed Essick
Spectral siren measurements of the Hubble constant () rely on correlations between observed detector-frame masses and luminosity distances. Features in the source-frame mass d…
