Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit

Kavli Affiliate: John D. Silverman | First 5 Authors: Wenke Ren, Hengxiao Guo, Yue Shen, John D. Silverman, Colin J. Burke | Summary: We introduce an improved method for decomposing the emission of active galactic nuclei (AGN) and their host galaxies using templates from principal component analysis (PCA). This approach integrates prior information from PCA […]

Nonparametric analysis of correlations in the binary black hole population with LIGO-Virgo-KAGRA data

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Jack Heinzel, Matthew Mould, Salvatore Vitale, , | Summary: Formation channels of merging compact binaries imprint themselves on the distributions and correlations of their source parameters. But current understanding of this population observed in gravitational waves is hindered by simplified parametric models. We overcome these limitations using […]

PixelPop: High Resolution Nonparameteric Inference of Gravitational-Wave Populations in Multiple Dimensions

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Jack Heinzel, Matthew Mould, Sofía Álvarez-López, Salvatore Vitale, | Summary: The origins of merging compact binaries observed by gravitational-wave detectors remains highly uncertain. Several astrophysical channels may contribute to the overall merger rate, with distinct formation processes imprinted on the structure and correlations in the underlying distributions […]
