Spatially Offset Active Galactic Nuclei in the Very Large Array Sky Survey: Tracers of Galaxy Mergers and Wandering Massive Black Holes
R. Scott Barrows, Julia M. Comerford
The remnants of galaxy mergers may host multiple off-nuclear massive black holes (MBHs), some of which may wander indefinitely within the host galaxy halos. Tracing the population…
The Redshift Evolution of Ultraluminous X-Ray Sources out to z~0.5: Comparison with X-Ray Binary Populations and Contribution to the Cosmic X-Ray Background
R. Scott Barrows, Julia M. Comerford, Daniel Stern +1
Ultraluminous X-ray sources (ULXs) are thought to be powerful X-ray binaries (XRBs) and may contribute significantly to the redshift-dependent X-ray emission from star forming gala…
An Active Galactic Nucleus Caught in the Act of Turning Off and On
Julia M. Comerford, R. Scott Barrows, Francisco Müller-Sánchez +5
We present the discovery of an active galactic nucleus (AGN) that is turning off and then on again in the z=0.06 galaxy SDSS J1354+1327. This episodic nuclear activity is the resul…
Shocks and Spatially Offset Active Galactic Nuclei Produce Velocity Offsets in Emission Lines
Julia M. Comerford, R. Scott Barrows, Jenny E. Greene +1
While 2% of active galactic nuclei (AGNs) exhibit narrow emission lines with line-of-sight velocities that are significantly offset from the velocity of the host galaxy's stars, th…
The Origin of Double-peaked Narrow Lines in Active Galactic Nuclei II: Kinematic Classifications for the Population at z < 0.1
Rebecca Nevin, Julia Comerford, Francisco Müller-Sánchez +2
We present optical longslit observations of the complete sample of 71 Type 2 active galactic nuclei (AGNs) with double-peaked narrow emission lines at in the Sloan Digita…
