TDCOSMO IV: Hierarchical time-delay cosmography -- joint inference of the Hubble constant and galaxy density profiles
S. Birrer, A. J. Shajib, A. Galan +24
The H0LiCOW collaboration inferred via gravitational lensing time delays a Hubble constant km s, describing deflector mass density pro…
Intra Cluster Light properties in the CLASH-VLT cluster MACS J1206.2-0847
V. Presotto, M. Girardi, M. Nonino +46
We aim at constraining the assembly history of clusters by studying the intra cluster light (ICL) properties, estimating its contribution to the fraction of baryons in stars, f*, a…
CLASH-VLT: Constraints on the Dark Matter Equation of State from Accurate Measurements of Galaxy Cluster Mass Profiles
Barbara Sartoris, Andrea Biviano, Piero Rosati +39
A pressureless scenario for the Dark Matter (DM) fluid is a widely adopted hypothesis, despite the absence of a direct observational evidence. According to general relativity, the…
CLASH-VLT: spectroscopic confirmation of a z=6.11 quintuply lensed galaxy in the Frontier Fields Cluster RXC J2248.7-4431
I. Balestra, E. Vanzella, P. Rosati +41
We present VIsible Multi-Object Spectrograph (VIMOS) observations of a z 6 galaxy quintuply imaged by the Frontier Fields galaxy cluster RXC J2248.7-4431 (z=0.348). This sub-L^*, h…
CLASH-VLT: The mass, velocity-anisotropy, and pseudo-phase-space density profiles of the z=0.44 galaxy cluster MACS 1206.2-0847
A. Biviano, P. Rosati, I. Balestra +44
We use an unprecedented data-set of about 600 redshifts for cluster members, obtained as part of a VLT/VIMOS large programme, to constrain the mass profile of the z=0.44 cluster MA…
A low-mass cut-off near the hydrogen burning limit for Salpeter-like initial mass functions in early-type galaxies
Matteo Barnabè, Chiara Spiniello, Léon V. E. Koopmans +3
We conduct a detailed investigation of the properties of the stellar initial mass function (IMF) in two massive early-type lens galaxies with velocity dispersions of sigma ~245 km/…
Weighing the Giants II: Improved Calibration of Photometry from Stellar Colors and Accurate Photometric Redshifts
Patrick L. Kelly, Anja von der Linden, Douglas E. Applegate +10
We present improved methods for using stars found in astronomical exposures to calibrate both star and galaxy colors as well as to adjust the instrument flat field. By developing a…
Two-dimensional kinematics of SLACS lenses - IV. The complete VLT-VIMOS data set
Oliver Czoske, Matteo Barnabè, Léon V. E. Koopmans +2
This paper presents the full VLT/VIMOS-IFU data set and related data products from an ESO Large Programme with the observational goal of obtaining two-dimensional kinematic data of…
Two-dimensional kinematics of SLACS lenses: III. Mass structure and dynamics of early-type lens galaxies beyond z ~ 0.1
Matteo Barnabe, Oliver Czoske, Leon V. E. Koopmans +2
We combine in a self-consistent way the constraints from both gravitational lensing and stellar kinematics to perform a detailed investigation of the internal mass distribution, am…
The X-Shooter Lens Survey - I. Dark-Matter Domination and a Salpeter-type IMF in a Massive Early-type Galaxy
C. Spiniello, L. V. E. Koopmans, S. C. Trager +2
We present the first results from the X-shooter Lens Survey (XLENS): an analysis of the massive early-type galaxy SDSS J1148+1930 at redshift z=0.444. We combine its extended kinem…
Quantifying dwarf satellites through gravitational imaging: the case of SDSS J120602.09+514229.5
S. Vegetti, O. Czoske, L. V. E. Koopmans.
SDSS J120602.09+514229.5 is a gravitational lens system formed by a group of galaxies at redshift z=0.422 lensing a bright background galaxy at redshift z=2.001. The main peculiari…
The non-evolving internal structure of early-type galaxies: the case study SDSS J0728+3835 at z = 0.206
Matteo Barnabe, Matthew W. Auger, Tommaso Treu +4
We study the internal dynamical structure of the early-type lens galaxy SDSS J0728+3835 at z = 0.206. The analysis is based on two-dimensional kinematic maps extending out to 1.7 e…
The mass distribution of a moderate redshift galaxy group and brightest group galaxy from gravitational lensing and kinematics
J. P. McKean, M. W. Auger, L. V. E. Koopmans +6
The gravitational lens system CLASS B2108+213 has two radio-loud lensed images separated by 4.56 arcsec. The relatively large image separation implies that the lensing is caused by…
