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…
Active Galactic Nuclei signatures in Red Geyser galaxies from Gemini GMOS-IFU observations
G. S. Ilha, R. A. Riffel, T. V. Ricci +8
Red Geysers are quiescent galaxies with galactic scale ionised outflows, likely due to low-luminosity Active Galactic Nuclei (AGN). We used Gemini GMOS-IFU observations of the inne…
Gas phase metallicity determinations in nearby AGNs with SDSS-IV MaNGA: evidence of metal poor accretion
Janaína C. do Nascimento, Oli L. Dors, Thaisa Storchi-Bergmann +8
We derive the metallicity (traced by the O/H abundance) of the Narrow Line Region ( NLR) of 108 Seyfert galaxies as well as radial metallicity gradients along their galaxy disks an…
