The Physics of the Coronal Line Region for Galaxies in MaNGA

James Negus, Julia M. Comerford, Francisco Müller Sánchez +4

The fundamental nature and extent of the coronal line region (CLR), which may serve as a vital tracer for Active Galactic Nucleus (AGN) activity, remain unresolved. Previous studie…

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…

A Catalog of Broad Hα and Hβ Active Galactic Nuclei in MaNGA

James Negus, Julia M. Comerford, Francisco Müller Sánchez

Broad H and H emission lines (FWHM > 1,000 km s) are incredibly efficient tracers of the high-velocity clouds encircling Active Galactic Nuclei (AGN). As a result, w…

A Catalog of 71 Coronal Line Galaxies in MaNGA: [NeV] is an Effective AGN Tracer

James Negus, Julia M. Comerford, Francisco Muller Sanchez +5

Despite the importance of AGN in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation…

A Catalog of 406 AGNs in MaNGA: A Connection between Radio-mode AGN and Star Formation Quenching

Julia M. Comerford, James Negus, Francisco Müller-Sánchez +8

Accurate active galactic nucleus (AGN) identifications and spatially resolved host galaxy properties are a powerful combination for studies of the role of AGNs and AGN feedback in…

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…
