First Data Release of the COSMOS Lyman-Alpha Mapping And Tomography Observations: 3D Lyman- Forest Tomography at 2.05 < z < 2.55
Khee-Gan Lee, Alex Krolewski, Martin White +21
Faint star-forming galaxies at can be used as alternative background sources to probe the Lyman- forest in addition to quasars, yielding high sightline densities tha…
A Detection of ~2.3 Cosmic Voids from 3D Lyman- Forest Tomography in the COSMOS Field
Alex Krolewski, Khee-Gan Lee, Martin White +10
We present the most distant detection of cosmic voids () and the first detection of three-dimensional voids in the Lyman- forest. We used a 3D tomographic map of the…
CLASH-VLT: A Highly Precise Strong Lensing Model of the Galaxy Cluster RXC J2248.7-4431 (Abell S1063) and Prospects for Cosmography
G. B. Caminha, C. Grillo, P. Rosati +32
We perform a comprehensive study of the total mass distribution of the galaxy cluster RXCJ2248 () with a set of high-precision strong lensing models, which take advantage…
CLASH-VLT: Insights on the mass substructures in the Frontier Fields Cluster MACS J0416.1-2403 through accurate strong lens modeling
C. Grillo, S. H. Suyu, P. Rosati +25
We present a detailed mass reconstruction and a novel study on the substructure properties in the core of the CLASH and Frontier Fields galaxy cluster MACS J0416.1-2403. We show an…
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…
