Spheroids scaling relations over cosmic time
TL;DR: In this paper, the authors report on recent measurements of two scaling relations of spheroids in the distant universe: the Fundamental Plane, and the relation between lensing velocity dispersion and stellar velocities.

TL;DR: In this article, an Ultra-Deep Field Survey (UDF) with WFIRST was proposed to reveal galaxies and AGNs at the faint end of the LF, at or beyond the epoch of reionization, and tracing their LSS environments.
Journal ArticleDOI
Wide field imaging of distant clusters
TL;DR: Wide field imaging is key to understanding the build-up of distant clusters and their galaxy population as mentioned in this paper, focusing on the so far unexplored outskirts of clusters, where infalling galaxies first hit the cluster potential and the hot intracluster medium.
Journal ArticleDOI
Mass distribution and orbital anisotropy of early-type galaxies: constraints from the Mass Plane
TL;DR: In this article, the authors show that the mass plane of early-type galaxies is less tilted than the fundamental plane and the two have comparable associated scatter, which can be used to constrain the mass distribution and internal dynamics of these galaxies.
Journal ArticleDOI
CARAMEL-gas: A Step toward Fast Empirical Models of the Broad-line-emitting Gas
Peter R. Williams,Tommaso Treu +1 more
TL;DR: In this article , an alternative approach aimed at describing the underlying broad emission line region (BLR) gas distribution, by exploiting simple numerical recipes to connect it with emissivity, is presented.
