Description
The LIGO–Virgo–KAGRA collaboration has reported several detections of massive binary black holes with total masses exceeding 100 M⊙. In addition to their large masses, some of these systems exhibit evidence of high component spins. On the other hand, owing to the short duration of their signals, these events could alternatively be explained by other transient sources. In this study, we propose a method to test their consistency with circular binary systems by examining the distribution of binary orientations. In this talk, I will present the methodology and its application to LIGO–Virgo–KAGRA events.
