SDSS-IV MaNGA: What Shapes The Distribution Of Metals In Galaxies? Exploring The Roles Of The Local Gas Fraction And Escape Velocity
J. K. Barrera-Ballesteros, T. Heckman, S. F. Sanchez +6
We determine the local metallicity of the ionized gas for more than star forming regions (spaxels) located in 1023 nearby galaxies included in the SDSS-IV MaNGA IF…
SDSS-IV MANGA: Spatially Resolved Star Formation Main Sequence and LI(N)ER Sequence
B. C. Hsieh, Lihwai Lin, J. H. Lin +17
We present our study on the spatially resolved H_alpha and M_star relation for 536 star-forming and 424 quiescent galaxies taken from the MaNGA survey. We show that the star format…
Serendipitous discovery of an optical emission line jet in NGC\,232
C. Lopez-Coba, S. F. Sanchez, I. Cruz-Gonzalez +9
We report the detection of a highly collimated linear emission-line structure in the spiral galaxy NGC\,232 through the use of integral field spectroscopy data from the All-weather…
Star formation is boosted (and quenched) from the inside out: radial star formation profiles from MaNGA
Sara L. Ellison, Sebastian F. Sanchez, Hector Ibarra-Medel +3
The tight correlation between total galaxy stellar mass and star formation rate (SFR) has become known as the star forming main sequence. Using ~487,000 spaxels from galaxies obser…
SSDSS IV MaNGA - Properties of AGN host galaxies
S. F. Sanchez, V. Avila-Reese, H. Hernandez-Toledo +22
We present here the characterization of the main properties of a sample of 98 AGN host galaxies, both type-II and type-I, in comparison with those of about 2700 non-active galaxies…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
