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…
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…
The stellar orbit distribution in present-day galaxies inferred from the CALIFA survey
Ling Zhu, Glenn van de Ven, Remco van den Bosch +16
Galaxy formation entails the hierarchical assembly of mass, along with the condensation of baryons and the ensuing, self-regulating star formation. The stars form a collisionless s…
Morpho-kinematic properties of field S0 bulges in the CALIFA survey
J. Mendez-Abreu, J. A. L. Aguerri, J. Falcon-Barroso +22
We study a sample of 28 S0 galaxies extracted from the integral-field spectroscopic (IFS) survey CALIFA. We combine an accurate two-dimensional (2D) multi-component photometric dec…
SDSS-IV MaNGA: Star formation cessation in low-redshift galaxies I. Dependence on stellar mass and structural properties
Enci Wang, Cheng Li, Ting Xiao +8
We investigate radial gradients in the recent star formation history (SFH) using 1917 galaxies with and integral-field spectroscopy from the ongoing MaNGA survey. For…
