Primordial Black Hole interpretation of the subsolar merger event S251112cm
The paper investigates whether a sub-solar mass merger event, S251112cm, could be explained by primordial black holes (PBHs). By combining merger rate calculations with current observational limits on PBH abundance and detector sensitivity, the analysis shows that a PBH origin for this event is compatible with existing constraints. This suggests sub-solar mergers are a viable probe for early Universe physics and dark matter.
