The hyperplane of early-type galaxies: using stellar population properties to increase the precision and accuracy of the fundamental plane as a distance indicator

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Matthew Colless, Arjen van der Wel, Sam P. Vaughan, Khaled Said | Summary: We use deep spectroscopy from the SAMI Galaxy Survey to explore the precision of the fundamental plane of early-type galaxies (FP) as a distance indicator for future single-fibre spectroscopy surveys. We study […]

Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit

Posted by dbos Tokyo

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 […]

Gravitational waves from mergers of Population III binary black holes: roles played by two evolution channels

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Boyuan Liu, Tilman Hartwig, Nina S. Sartorio, Irina Dvorkin, Guglielmo Costa | Summary: The gravitational wave (GW) signal from binary black hole (BBH) mergers is a promising probe of Population III (Pop III) stars. To fully unleash the power of the GW probe, one important step is […]

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

Posted by dbos MIT

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

Posted by dbos MIT

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 […]
