abstract
A follow-up of a subsolar black hole candidate identified in the second part of the third observing run of the LIGO-Virgo-KAGRA collaboration is carried out. With a search signal-to-noise ratio of $8.90$ and a false-alarm rate of 1 per 5 years, close to the usual thresholds for claiming a gravitational-wave event, we cannot exclude a noise origin. A complete Bayesian parameter estimation of this candidate, denoted SSM200308, reveals that if the signal originates from a compact binary coalescence, the component masses are $m_1= 0.62^{+0.46}_{-0.20} M_{\odot}$ and $m_2 = 0.27^{+0.12}_{-0.10} M_{\odot}$ (90% credible intervals) with at least one component being firmly subsolar, below the minimum mass of a neutron star. This discards the hypothesis that the signal comes from a standard binary neutron star. The signal coherence test between the two LIGO detectors brings support to a compact object coalescence origin.

Probing Primordial Black Hole Mergers in Clusters with Pulsar Timing Data
Bayesian analysis of IPTA DR2 shows scalar-induced gravitational waves dominate and PBH merger backgrounds are strongly disfavored relative to an astrophysical SMBHB explanation.

Parameter Estimation on LIGO-Virgo-KAGRA O4a Binary Merger Triggers with Sub-solar Mass Components
Bayesian re-analysis of the seven LVK O4a sub-solar-mass triggers finds three that are compatible with a sub-solar-mass component, though none rises to detection significance.

Is the formation of primordial black holes from single-field inflation compatible with standard cosmology?
Producing primordial black holes in single-field inflation typically forces more than about 55 e-folds after CMB-mode exit, conflicting with standard reheating unless the model is retuned or reheating is exotic.
