Using LIGO O3 continuous-wave search data, the authors place the first constraints on ellipticities of self-interacting fermionic dark matter admixed neutron stars and exclude regions of the DM parameter space for masses in [0.1,10] GeV.

O4a gravitational-wave data give 95% CL upper limits f_PBH ~ 1e-2 to 1e-4 for monochromatic primordial black holes with mean masses 0.6-100 M_sun, with no evidence of a PBH merger component.
Radio telescopes outperform other experiments at detecting high-frequency gravitational waves from primordial black hole mergers and boson clouds through conversion to radio signals in magnetic fields.
BlackHawk v3.0 adds Hawking temperatures and greybody factors for multiple regular black hole metrics to an existing public code via numerical routines.
Sets upper limits on primordial black hole dark matter fraction using extragalactic gamma-ray background, claiming these are the tightest indirect constraints for the mass range.
Two inference frameworks are developed for neutron star properties from r-mode gravitational waves, one assuming electromagnetic distance and the other estimating distance via universal relations plus an assumed equation of state, with Fisher-matrix error estimates.

Inferring neutron star properties through gravitational waves from r-modes and their relativistic counterparts
Two inference frameworks are developed for neutron star properties from r-mode gravitational waves, one assuming electromagnetic distance and the other estimating distance via universal relations plus an assumed equation of state, with Fisher-matrix error estimates.
