The Swift BAT-detected Seyfert 1 Galaxies: X-ray Broadband Properties and Warm Absorbers
Lisa M. Winter, Sylvain Veilleux, Barry McKernan +1
We present results from an analysis of the broad-band, 0.3-195 keV, X-ray spectra of 48 Seyfert 1-1.5 sources detected in the very hard X-rays with the Swift Burst Alert Telescope…
Optical Spectroscopy of Halpha Filaments in Cool Core Clusters: Kinematics, Reddening, and Sources of Ionization
Michael McDonald, Sylvain Veilleux, David S. N. Rupke
We have obtained deep, high spatial and spectral resolution, long-slit spectra of the Halpha nebulae in the cool cores of 9 galaxy clusters. This sample provides a wealth of inform…
An Ionization Cone in the Dwarf Starburst Galaxy NGC 5253
Jordan Zastrow, M. S. Oey, Sylvain Veilleux +2
There are few observational constraints on how the escape of ionizing photons from starburst galaxies depends on galactic parameters. Here, we report on the first major detection o…
Nuclear Rings in Galaxies---A Kinematic Perspective
Lisa M. Mazzuca, Robert A. Swaters, Johan H. Knapen +1
We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their r…
Chandra Discovery of a Binary Active Galactic Nucleus in Mrk 739
Michael Koss, Richard Mushotzky, Ezequiel Treister +6
We have discovered a binary AGN in the galaxy Mrk 739 using Chandra and Swift BAT. We find two luminous L_2-10 keV=1.1*10^43 and 1.0*10^42 erg/s, unresolved nuclei with a projected…
Host Galaxy Properties of the Swift BAT Ultra Hard X-ray Selected AGN
Michael Koss, Richard Mushotzky, Sylvain Veilleux +5
We have assembled the largest sample of ultra hard X-ray selected (14-195 keV) AGN with host galaxy optical data to date, with 185 nearby (z<0.05), moderate luminosity AGN from the…
