Recoiling Black Hole Candidates from Spatially Offset Broad Emission Lines in MaNGA
R. Scott Barrows, Julia M. Comerford, James Negus +1
From the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we identify 14 off-nuclear broad (FWHM>1000 km/s) Halpha and/or Hbeta emission line sources that indica…
An Excess of AGNs Triggered by Galaxy Mergers in MaNGA Galaxies of Stellar Mass
Julia M. Comerford, Rebecca Nevin, James Negus +7
To facilitate new studies of galaxy merger driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over…
Merger-Driven Growth of Intermediate-mass Black Holes: Constraints from Hubble Space Telescope Imaging of Hyper-luminous X-Ray Sources
R. Scott Barrows, Mar Mezcua, Julia M. Comerford +1
Hyper-luminous X-ray sources (HLXs) are extragalactic off-nuclear X-ray sources with luminosities exceeding the theoretical limit for accretion onto stellar-mass compact objects. M…
A Census of WISE-selected Dual and Offset AGN Across the Sky: New Constraints on Merger-Driven Triggering of Obscured AGN
R. Scott Barrows, Julia M. Comerford, Daniel Stern +1
Pairs of galaxies hosting active galactic nuclei (AGN) are powerful probes of merger-driven supermassive black hole (SMBH) growth as they can resolve individual AGN and trace merge…
A declining major merger fraction with redshift in the local Universe from the largest-yet catalog of major and minor mergers in SDSS
R. Nevin, L. Blecha, J. Comerford +4
It is difficult to accurately identify galaxy mergers and it is an even larger challenge to classify them by their mass ratio or merger stage. In previous work we used a suite of s…
Towards a More Complete Optical Census of Active Galactic Nuclei, Via Spatially-Resolved Spectroscopy
Julia M. Comerford, James Negus, R. Scott Barrows +4
While emission-line flux ratio diagnostics are the most common technique for identifying active galactic nuclei (AGNs) in optical spectra, applying this approach to single fiber sp…
