The Masses of Lyman Break Galaxies
TL;DR: In this article, three different star formation prescriptions, and use semi-analytic methods applied to the now-standard ΛCDM theory of hierarchical structure formation, were used to show how these assumptions about star formation affect the predicted masses of the stars in these galaxies and the masses of dark matter halos that host them.
Galaxy Evolution with LSST
Jennifer M. Lotz,H. C. Ferguson,Lee Armus,L. F. Barrientos,James G. Bartlett,M. R. Blanton,Kirk D. Borne,C. Bridge,Mark Dickinson,Harold Francke,Gaspar Galaz,Eric Gawiser,Kirk Gilmore,Robert H. Lupton,Jeffrey A. Newman,Nelson D. Padilla,Brant Robertson,Rok Roškar,A. Stanford,Risa H. Wechsler +19 more
TL;DR: The LSST Galaxies Working Group as discussed by the authors measured the multivariate properties of the galaxy population including trends with redshift and environment, and determined how the evolving multivariate galaxy properties and scaling relations depend on this density field, and on the distribution and evolution of dark matter halos.

Early-type galaxy density profiles from IllustrisTNG: III. Effects on outer kinematic structure
Yunchong Wang,Shude Mao,Mark Vogelsberger,Volker Springel,Lars Hernquist,Risa H. Wechsler,Stanford,Naoc +7 more
TL;DR: In this paper, the authors verify the influence of stellar assembly on the formation of non-canonical kinematic features through mock ETGs with well-studied density profiles in IllustrisTNG and find that the outer kurtosis and anisotropy correlate with different stellar assembly components.
