X-ray Reverberation Mapping of Ark 564 using Gaussian Process Regression
Collin D. Lewin, Erin Kara, Daniel R. Wilkins +15
Ark 564 is an extreme high-Eddington Narrow-line Seyfert 1 galaxy, known for being one of the brightest, most rapidly variable soft X-ray AGN, and for having one of the lowest temp…
The Super-Massive Black Hole close environment in Active Galactic Nuclei
W. Alston, M. Giustini, P. O. Petrucci
Active Galactic Nuclei are powered by accretion of matter onto a supermassive black hole (SMBH) of mass Mbh ~ 10^{5}-10^{9} Msun. The accretion process is indeed the most efficient…
XMM-Newton Observations of the Narrow-Line Seyfert 1 Galaxy IRAS 132243809 : X-ray Spectral Analysis II
Jiachen Jiang, Thomas Dauser, Andrew C. Fabian +4
Previously, we modelled the X-ray spectra of the narrow-line Seyfert 1 galaxy IRAS 132243809 using a disc reflection model with a fixed electron density of cm.…
Ejection-accretion connection in NLS1 AGN 1H 1934-063
Yerong Xu, Ciro Pinto, Erin Kara +7
Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena and represent fundamental mechanisms regulating the growth of the central supermass…
High-density disc reflection spectroscopy of low-mass active galactic nuclei
L. Mallick, A. C. Fabian, J. A. García +13
The standard alpha-disc model predicts an anti-correlation between the density of the inner accretion disc and the black hole mass times square of the accretion rate, as seen in hi…
