Probing Stellar Populations and Interstellar Medium in Early-Type Central Galaxies
Vanessa Lorenzoni, Sandro B. Rembold, Reinaldo R. de Carvalho
In this study, we analyse the characteristics of stellar populations and the interstellar medium (ISM) in 15,107 early-type central galaxies from the SPIDER survey. Using optical s…
Mapping the stellar population and gas excitation of MaNGA galaxies with MEGACUBES. Results for AGN versus control sample
Rogério Riffel, Nicolas D. Mallmann, Sandro B. Rembold +11
We present spaxel-by-spaxel stellar population fits for the 10 thousand MaNGA datacubes. We provide multiple extension fits files, nominated as MEGACUBES, with maps of severa…
Nuclear activity in QSO 2's mainly triggered by galaxy mergers
Bruna L. C. Araujo, Thaisa Storchi-Bergmann, Sandro B. Rembold +2
We investigate the role of the close environment on the nuclear activity of a sample of 436 nearby () QSO 2's -- selected from SDSS-III spectra, via comparison of their envi…
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…
