TLDR
The authors measured nebular oxygen abundances for 204 emission-line galaxies with redshifts 0.3 -20, consistent with scenarios whereby the formation epoch for less massive galaxies is more recent than for massive galaxies.Abstract:

Helly,Adrian Jenkins,Yetli Rosas-Guevara,Simon D. M. White,Maarten Baes,C. M. Booth,C. M. Booth,Peter Camps,Julio F. Navarro,Yan Qu,Alireza Rahmati,Till Sawala,Peter A. Thomas,James W. Trayford +24 more
TL;DR: The Virgo Consortium's EAGLE project as discussed by the authors is a suite of hydrodynamical simulations that follow the formation of galaxies and black holes in representative volumes, where thermal energy is injected into the gas, allowing winds to develop without predetermined speed or mass loading factors.

Joshua S. Speagle,Joshua S. Speagle,Charles L. Steinhardt,Charles L. Steinhardt,Peter Capak,John D. Silverman +5 more
TL;DR: In this article, the authors investigate the evolution of the star-forming galaxy (SFG) main sequence (MS) in stellar mass and star formation rate (SFR) out to z ~ 6.4 Gyr.

Bruce T. Draine,Daniel A. Dale,George J. Bendo,Karl D. Gordon,J. D. T. Smith,Lee Armus,Charles W. Engelbracht,George Helou,Robert C. Kennicutt,Robert C. Kennicutt,Aigen Li,Helene Roussel,Fabian Walter,Daniela Calzetti,John Moustakas,John Moustakas,Eric J. Murphy,George H. Rieke,Caroline Bot,David Hollenbach,Kartik Sheth,Harry I. Teplitz +21 more
TL;DR: Physical dust models for 65 galaxies in SINGS that are strongly detected in the four IRAC bands and three MIPS bands were presented for each galaxy as discussed by the authors, estimating the total dust mass, the fraction of the dust mass contributed by PAHs, and the intensity of the starlight heating the dust grains.

The Global Schmidt law in star forming galaxies
TL;DR: In this paper, the Schmidt law was used to model the global star formation law over the full range of gas densities and star formation rates observed in galaxies, and the results showed that the SFR scales with the ratio of the gas density to the average orbital timescale.
