Subsolar strange star mergers produce a lower post-merger-to-cutoff GW frequency ratio than neutron star mergers, cleanly separating the two classes across equations of state and mass ratios.
No sub-solar-mass compact-binary mergers were found in LIGO O4a data, giving 90% merger-rate upper limits of 110-10000 Gpc^-3 yr^-1 and weak new dark-matter constraints.
The paper reviews primordial black hole formation during the cosmic QCD phase transition in a microscopical model and explores how beyond-Standard-Model physics affects the equation of state and PBH probability distributions as dark matter candidates.
Latest GW neutron star merger rates are consistent with short GRBs being produced by BNS mergers if jets are wide or rates low, with NSBH mergers subdominant.
