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

TL;DR: A morphological catalogue for 670,000 galaxies in the Sloan Digital Sky Survey in two flavours: T-Type, related to the Hubble sequence, and Galaxy Zoo 2 (GZ2 hereafter) classification scheme, provided by combining accurate existing visual classification catalogues with machine learning.

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.

Straatman,Kim-Vy Tran,Adam Tomczak,Pieter G. van Dokkum +24 more
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 article, very deep HST, VLT, and Spitzer photometry of galaxies at 2 2 galaxies was analyzed and it was shown that the estimated distributions of these properties do not change significantly when IRAC data are added to the UBVIJHK photometry.

TL;DR: In this article, the authors used a sample of BzK-selected star-forming galaxies, drawn from the Cosmic Evolution Survey, to perform stacking analysis of their 1.4 GHz radio continuum as a function of different stellar population properties, after cleaning the sample from contamination by active galactic nuclei.

TL;DR: In this article, the authors study the buildup of the bimodal galaxy population using the NEWFIRM Medium-Band Survey, which provides excellent redshifts and well-sampled spectral energy distributions of {approx}27, 000 galaxies with K 3 x 10{sup 10} M{sub sun} increases by a factor of {approximately}10 from z − 2 to the present day, whereas the mass density in star-forming galaxies is flat or decreases over the same time period.

Bulge Formation by the Coalescence of Giant Clumps in Primordial Disk Galaxies
TL;DR: In this article, the authors studied the properties of the bulges formed by the supernova feedback in the early universe and found that they are all thick, slowly rotating, and have a high Sersic index, like classical bulges.
