An X-ray Spectral Analysis of the Central Regions of NGC 4593
L. W. Brenneman, C. S. Reynolds, J. Wilms +1
We present a detailed analysis of XMM-Newton EPIC-pn data for the Seyfert-1 galaxy NGC 4593. We discuss the X-ray spectral properties of this source as well as its variations with…
Constraining Black Hole Spin Via X-ray Spectroscopy
Laura W. Brenneman, Christopher S. Reynolds
We present an analysis of the observed broad iron line feature and putative warm absorber in the long 2001 XMM-Newton observation of the Seyfert-1.2 galaxy MCG-6-30-15. The new "ke…
The Interaction of 3C401 with the Surrounding Intracluster Medium
Christopher S. Reynolds, Laura W. Brenneman, John T. Stocke
We present an observation of the radio-galaxy 3C401 and the surrounding intracluster medium (ICM) of its host galaxy cluster by the Chandra X-ray Observatory. This luminous radio-g…
Black Hole Spin in AGN and GBHCs
Christopher S. Reynolds, Laura W. Brenneman, David Garofalo
We discuss constraints on black hole spin and spin-related astrophysics as derived from X-ray spectroscopy. After a brief discussion about the robustness with which X-ray spectrosc…
Iron Line Spectroscopy of NGC4593 with XMM-Newton: Where is the Black Hole Accretion Disk?
Christopher S. Reynolds, Laura W. Brenneman, Joern Wilms +1
We present an analysis of the 2-10keV XMM-Newton/EPIC-pn spectrum of the Seyfert-1 galaxy NGC4593. Apart from the presence of two narrow emission lines corresponding to the Kalpha…
Hubble Space Telescope observations of globular cluster systems along the Hubble sequence of spiral galaxies
Paul Goudfrooij, Jay Strader, Laura Brenneman +3
We have studied the globular cluster (GC) systems of 7 giant, edge-on spiral galaxies using Hubble Space Telescope imaging in V and I. The galaxy sample covers the Hubble types Sa…
