X-ray spectral and timing analysis of the Compton Thick Seyfert 2 galaxy NGC 1068

Indrani Pal, C. S. Stalin, M. L. Parker +2

We present the timing and spectral analysis of the Compton Thick Seyfert 2 active galactic nuclei NGC 1068 observed using {\it NuSTAR} and {\it XMM-Newton}. In this work for the fi…

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…

The X-ray Disk/Wind Degeneracy in AGN

M. L. Parker, G. A. Matzeu, J. H. Matthews +4

Relativistic Fe K emission lines from accretion disks and from disk winds encode key information about black holes, and their accretion and feedback mechanisms. We show that these…

Ionised Emission and Absorption in a Large Sample of Ultraluminous X-ray Sources

P. Kosec, C. Pinto, C. S. Reynolds +6

Most Ultraluminous X-ray sources (ULXs) are thought to be powered by super-Eddington accretion onto stellar-mass compact objects. Accretors in this extreme regime are naturally exp…

The nature of the extreme X-ray variability in the NLS1 1H 0707-495

M. L. Parker, W. N. Alston, L. Härer +11

We examine archival XMM-Newton data on the extremely variable narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) 1H 0707-495. We construct fractional excess variance (Fvar)…

MAXI J1820+070 with NuSTAR II. Flaring during the hard to soft state transition with a long soft lag

D. J. K. Buisson, A. C. Fabian, P. Gandhi +6

We continue the analysis of NuSTAR data from the recent discovery outburst of MAXI J1820+070 (optical counterpart ASASSN-18ey), focussing on an observation including unusual flarin…
