Oxygen yields as a constraint on feedback processes in galaxies

12 Sep 2019 Lara-Lopez Maritza A. De Rossi Maria Emilia Pilyugin Leonid S. Gallazzi Anna Hughes Thomas M. Zinchenko Igor A.

We study the interplay between several properties determined from Optical and a combination of Optical/Radio measurements, such as the effective Oxygen yield (y_eff), the star formation efficiency, gas metallicity, depletion time, gas fraction, and baryonic mass(M_bar), among others. We use spectroscopic data from the SDSS survey, and HI information from the ALFALFA survey to build a statistically significant sample of more than 5,000 galaxies... (read more)
