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…
Solar abundance ratios of the iron-peak elements in the Perseus Cluster
Hitomi Collaboration
The metal abundance of the hot plasma that permeates galaxy clusters represents the accumulation of heavy elements produced by billions of supernovae. Therefore, X-ray spectroscopy…
Disk-Wind Connection During the Heartbeats of GRS 1915+105
Abderahmen Zoghbi, J. M. Miller, A. L. King +14
Disk and wind signatures are seen in the soft state of Galactic black holes, while the jet is seen in the hard state. Here we study the disk-wind connection in the class of var…
Revealing the X-ray source in IRAS 13224-3809 through flux-dependent reverberation lags
E. Kara, A. C. Fabian, E. M. Cackett +2
IRAS 13224-3809 was observed in 2011 for 500 ks with the XMM-Newton observatory. We detect highly significant X-ray lags between soft (0.3 - 1 keV) and hard (1.2 - 5 keV) energies.…
Cluster cores and cooling flows
A. C. Fabian
The gas temperature in the cores of many clusters of galaxies drops inward by about a factor of three or more within the central 100 kpc radius. The radiative cooling time drops ov…
The shape of the relativistic iron K-alpha line from MCG6--6-30-15 measured with the Chandra HETGS and RXTE
J. C. Lee, K. Iwasawa, J. C. Houck +3
We confirm the detection of the relativistically broadened iron K-alpha emission at 6.4 keV with simultaneous Chandra HETGS and RXTE PCA observations. Heavily binned HETGS data sho…
