XMM-Newton Archival Study of the ULX Population in Nearby Galaxies
L. M. Winter, R. F. Mushotzky, C. S. Reynolds
We present the results of an archival XMM-Newton study of the bright X-ray point sources (L_X > 10^38 erg/s) in 32 nearby galaxies. From our list of approximately 100 point sources…
Oxygen and Iron Abundances in Nearby Galaxies Using Ultraluminous X-ray Sources
Lisa M. Winter, Richard F. Mushotzky, Christopher S. Reynolds
We determined oxygen and iron abundances of the interstellar medium (ISM) using K-shell (O) and L-shell (Fe) X-ray photo-ionization edges towards Ultra luminous X-ray sources (ULXs…
Evidence for Gravitational Infall of Matter onto the Super-Massive Black Hole in the quasar PG 1211+143?
J. N. Reeves, K. Pounds, P. Uttley +5
We report the detection of redshifted iron K-alpha absorption lines in the Chandra LETG spectrum of the narrow-line quasar, PG 1211+143. The absorption lines are observed at 4.22 k…
Simultaneous Ultraviolet and X-ray Observations of the Seyfert Galaxy NGC 4151. I. Physical Conditions in the X-ray Absorbers
S. B. Kraemer, I. M. George, D. M. Crenshaw +9
We present a detailed analysis of the intrinsic X-ray absorption in the Seyfert 1 galaxy NGC 4151 using Chandra/HETGS data obtained 2002 May, as part of a program which included si…
An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
Radio Emission Associated with the ULX in Holmberg II
Neal A. Miller, Richard Mushotzky, Susan Neff
We report the detection of radio emission coincident with the ultraluminous X-ray source (ULX) in Holmberg II. The radio emission is diffuse and resolved, covering an area ~60 by 4…
