Mass Distribution Analysis

Kernel Density Estimation (KDE) of individual component masses (M₁ and M₂) with 90% confidence intervals. This reveals the underlying mass distribution of compact objects detected by LIGO, Virgo, and KAGRA.

Component Mass Distributions
Distribution of primary (M₁) and secondary (M₂) component masses with bootstrap-estimated 90% confidence intervals.

Final Mass

Final mass distribution of merger remnants.

Final Mass Distribution and Mass Gap Exploration
Shaded regions mark the neutron star zone (0-2.5 M☉) in blue, the mass gap (2.5-5 M☉) in yellow, and the black hole zone (5+ M☉) in purple.
