Description
Gravitational-wave observations provide a unique window into both black hole populations and cosmology. Using the latest transient catalog, GWTC-4, we investigate the presence of structure in the primary black hole mass distribution through agnostic modelling and compare the results with parametric approaches. We show that the ability to resolve specific features in the mass spectrum plays a key role in constraining the Hubble constant. We further discuss the limitations of current analyses and propose a novel framework aimed at mitigating systematic biases in these measurements.
