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:

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.

SUB-KILOPARSEC ALMA IMAGING of COMPACT STAR-FORMING GALAXIES at z ∼ 2.5: REVEALING the FORMATION of DENSE GALACTIC CORES in the PROGENITORS of COMPACT QUIESCENT GALAXIES

TL;DR: In this paper, the Atacama Large Millimeter/submillimeter Array (ALMA) 870 μm dust continuum maps of six massive, compact, dusty star-forming galaxies at z ~ 2.5 are presented for their small rest-frame optical sizes (r_e,F160W ~ 1.6 kpc) and high stellar mass densities that suggest that they are direct progenitors of compact quiescent galaxies.

Two conditions for galaxy quenching: compact centres and massive haloes
TL;DR: In this article, the roles of two classes of quenching mechanisms for central and satellite galaxies in the SDSS were investigated, and the observed correlations can be explained if quenched due to central compactness is rapid while quench due to halo mass is slow.

TL;DR: In this paper, a median stack of the rest-frame optical spectra for 171 photometrically quiescent galaxies at 1.4 < z < 2.2 from the 3D-HST grism survey was used to identify metal absorption lines in the stacked spectrum.

Balance among gravitational instability, star formation and accretion determines the structure and evolution of disc galaxies
TL;DR: In this paper, a general theoretical model for how star-forming galaxies change from clumpy and gas rich disks to rather quiescent stellar-dominated disks with specific star formation rates lower by factors of a few tens.
