TLDR
In this article, the authors study the evolution of scaling relations that compare the effective density (Sigma(e), r 9.6 -9.3M(circle dot) kpc(-2), allowing the most efficient identification of compact SFGs and quiescent galaxies at every redshift.Abstract:
We study the evolution of the scaling relations that compare the effective density (Sigma(e), r 9.6 -9.3M(circle dot) kpc(-2), allowing the most efficient identification of compact SFGs and quiescent galaxies at every redshift.read more

Star formation is boosted (and quenched) from the inside-out: radial star formation profiles from MaNGA
Sara L. Ellison,Sebastián F. Sánchez,Hector Ibarra-Medel,Braulio Antonio,Braulio Antonio,J. Trevor Mendel,Jorge K. Barrera-Ballesteros +6 more
TL;DR: In this paper, the authors investigated the SFR profiles of 864 galaxies as a function of their position relative to the global star forming main sequence (Delta SFR), and found that for quiescent/passive galaxies that lie at least a factor of 10 below the global main sequence, there is an analogous deficit of star formation throughout the galaxy with the lowest values of Delta Sigma_SFR in the central 3 kpc.

TL;DR: In this paper, the authors studied galactic star-formation activity as a function of environment and stellar mass over 0.5 9 (9.5) and showed that the effects of quenching related to stellar mass and environment are not separable.

TL;DR: In this paper, a kinematical decomposition of the stellar component into a spheroidal and a disc component (spheroid-to-total ratio, S/T) and the concentration of stellar mass density profile (C_{82}$) was proposed to quantify the relationship between galaxy morphology and star formation.

TL;DR: In this paper, the authors explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M*), using data from the FourStar Galaxy Evolution Survey (ZFOURGE) in combination with far-IR imaging from the Spitzer and Herschel observatories.

The evolving relations between size, mass, surface density, and star formation in 3x10^4 galaxies since z=2
Rik J. Williams,Rik J. Williams,Ryan Quadri,Marijn Franx,Pieter G. van Dokkum,Sune Toft,Sune Toft,Mariska Kriek,Ivo Labbé +8 more
TL;DR: In this paper, the authors investigate the correlations between star formation and galaxy structural parameters (size, stellar mass, and surface density) from z = 2 to the present, and find that massive quiescent galaxies (i.e., those with little or no star formation) occupy the extreme high end of the surface density distribution and follow a tight mass-size correlation, while star-forming galaxies show a broad range of both densities and sizes.
