Understanding X-ray reflection as a probe of accreting black holes
… radii and is applied to X-ray spectra of the narrow line Seyfert 1 galaxies 1H 0707-495, IRAS 13224-3809 and MCG-6-30-15 as well as the Galactic X-ray binary, Cygnus X-1. This illumination pattern of the accretion disc is a sensitive probe of the geometry of the corona that is illuminating the …

Estimating the stellar masses of NLS1 galaxies using multifrequency data
… stellar mass estimates for a sample of 141 narrow-line Seyfert 1 (NLS1) galaxies. NLS1s are active galactic nuclei (AGN) known for their relatively low black hole masses, disk-like host galaxies, high accretion rates and their ability to host powerful relativistic jets. The stellar masses …
