Star formation along the Hubble sequence: Radial structure of the star formation of CALIFA galaxies

Understand

The aim of this paper is to characterize the radial structure of the star formation rate (SFR) in galaxies in the nearby Universe as represented by the CALIFA survey.

• The sample under study contains 416 galaxies observed with IFS, covering a wide range of Hubble types and stellar masses.
• Spectral synthesis techniques are applied to obtain radial profiles of the intensity of the star formation rate in the recent past, and the local sSFR.
• To emphasize the behavior of these properties for galaxies that are on and off the main sequence of star formation (MSSF) we stack the individual radial profiles in bins of galaxy morphology and stellar masses.
