The Importance of Preventive Feedback: Inference from Observations of the Stellar Masses and Metallicities of Milky Way Dwarf Galaxies
Yu Lu,Andrew J. Benson,Andrew Wetzel,Andrew Wetzel,Andrew Wetzel,Yao-Yuan Mao,Stephanie Tonnesen,Annika H. G. Peter,Michael Boylan-Kolchin,Risa H. Wechsler,Risa H. Wechsler +10 more
TL;DR: In this article, the authors explore a semi-analytic galaxy formation model to understand how the feedback processes shape the satellite galaxies of the Milky Way (MW) using Markov Chain Monte Carlo.

TL;DR: In this paper, the authors present the calibration of the Dark Energy Survey Year 1 (DES Y1) weak lensing source galaxy redshift distributions from clustering measurements, by cross-correlating the positions of source galaxies with luminous red galaxies selected by the redMaGiC algorithm.

TL;DR: In this paper, the authors explore the relation between diffuse intracluster light (central galaxy included) and the galaxy cluster (baryonic and dark) matter distribution using a sample of 528 clusters at 0.2 ≤ z ≤ 0.35 found in the Dark Energy Survey (DES) Year 1 data.
