The Sloan Lens ACS Survey. VII. Elliptical Galaxy Scaling Laws from Direct Observational Mass Measurements
Adam S. Bolton,Adam S. Bolton,Tommaso Treu,Léon V. E. Koopmans,Raphael Gavazzi,Leonidas A. Moustakas,Scott Burles,David J. Schlegel,Randall B. Wayth +8 more
TL;DR: In this paper, the authors used a sample of 53 massive early-type strong gravitational lens galaxies with well-measured redshifts (ranging from z=0.06 to 0.36) and stellar velocity dispersions (between 175 and 400 km/s) from the SLACS Survey to derive numerous empirical scaling relations.
Journal ArticleDOI
The Dark Matter Distribution in the Central Regions of Galaxy Clusters
TL;DR: In this article, a spectroscopic study of six clusters each containing a dominant brightest cluster galaxy (BCG) with nearby gravitational arcs was performed. And the inner slope of the dark matter halo was compared with that predicted from CDM simulations.

TL;DR: In this article, the authors used adaptive optics-enabled imaging with deep spectroscopy to measure the three-dimensional motions of stars within a sample of Local Group dwarf galaxies that are the cleanest dark matter laboratories known in the nearby universe.
Journal ArticleDOI
Mass Modeling of Frontier Fields Cluster MACS J1149.5+2223 Using Strong and Weak Lensing
Emily Quinn Finney,Marusa Bradac,Kuang-Han Huang,Austin Hoag,Takahiro Morishita,Takahiro Morishita,Tim Schrabback,Tommaso Treu,Kasper B. Schmidt,Brian C. Lemaux,Xin Wang,Charlotte Mason +11 more
TL;DR: In this paper, the authors presented a map of the ratio of projected stellar mass to total mass, and found that the stellar mass fraction for this cluster peaks on the primary BCG.

TL;DR: In this article, the projected spatial offset between the ultraviolet continuum and Ly α emission for 65 lensed and unlensed galaxies in the Epoch of Reionization (5 ≤ z ≤ 7) was studied, in order to understand the potential for these offsets to confuse estimates of the Ly α properties observed in slit spectroscopy.
