Amuse-virgo. iii. mid-infrared photometry of early-type galaxies and limits on obscured nuclear emission
TL;DR: In this article, a census of low-level nuclear activity in Virgo Cluster early-type galaxies was conducted by searching for obscured emission using Spitzer Space Telescope mid-infrared (MIR) imaging at 24 µm.

Massive elliptical galaxies at $z \sim 0.2$ are well described by stars and a Navarro-Frenk-White dark matter halo
TL;DR: In this paper, the authors investigate the internal structure of elliptical galaxies at the expense of a joint lensing-dynamics analysis, and find that the distribution of the lensing only logarithmic slopes has a median value of 0.2.
Journal ArticleDOI
Modelling the AGN broad-line region using single-epoch spectra − II. Nearby AGNs
S. I. Raimundo,Marianne Vestergaard,Marianne Vestergaard,M. R. Goad,Catherine J. Grier,Peter R. Williams,Bradley M. Peterson,Bradley M. Peterson,Tommaso Treu +8 more
TL;DR: In this paper, the authors explore a new version of a Bayesian inference, physical model of the broad line region (BLR) which uses an individual spectrum and prior information on the BLR size from the radius-luminosity relation, to model the AGN BLR geometry and dynamics.
Journal ArticleDOI
Improving $z\sim7-11$ Galaxy Property Estimates with JWST/NIRCam Medium-Band Photometry
Guido Roberts-Borsani,Tommaso Treu,Charlotte Mason,Kasper B. Schmidt,Tucker Jones,Adriano Fontana +5 more
TL;DR: In this paper, the authors show that adding NIRCam images through a strategically chosen medium-band filter to common wide-band filters sets adopted by ERS and GTO programs delivers tighter constraints on these galactic properties.
Journal ArticleDOI
Rcs2 j232727.6-020437: an efficient cosmic telescope at z = 0:6986
Austin Hoag,Marusa Bradac,Kuang-Han Huang,Russell E. Ryan,Keren Sharon,Tim Schrabback,Kasper B. Schmidt,Benjamin Cain,Anthony H. Gonzalez,Hendrik Hildebrandt,Joannah L. Hinz,Brian C. Lemaux,Anja von der Linden,Lori M. Lubin,Tommaso Treu,Dennis Zaritsky +15 more
TL;DR: In this article, a detailed gravitational lens model of the galaxy cluster RCS2 J232727.6-020437 was presented, where the authors identify a strong emission line in the spectrum of one multiple image, likely confirming the redshift of that system to 2.083.
