Directly constraining the spatial coherence of the circumgalactic medium
A. Afruni, S. Lopez, P. Anshul +9
One of the biggest puzzles regarding the circumgalactic medium (CGM) is the structure of its cool ( K) gas phase. While the kinematics of quasar absorption systems sugge…
ACTPol: A polarization-sensitive receiver for the Atacama Cosmology Telescope
M. D. Niemack, P. A. R. Ade, J. Aguirre +39
The six-meter Atacama Cosmology Telescope (ACT) in Chile was built to measure the cosmic microwave background (CMB) at arcminute angular scales. We are building a new polarization…
Telltale signs of metal recycling in the circumgalactic medium of a galaxy
N. Tejos, S. López, C. Ledoux +15
We present gravitational-arc tomography of the cool-warm enriched circumgalactic medium (CGM) of an isolated galaxy (``G1'') at . Combining VLT/MUSE adaptive-optics…
The ALMA Frontier Fields Survey - IV. Lensing-corrected 1.1 mm number counts in Abell 2744, MACSJ0416.1-2403 and MACSJ1149.5+2223
A. M. Muñoz Arancibia, J. González-López, E. Ibar +15
[abridged] Characterizing the number counts of faint, dusty star-forming galaxies is currently a challenge even for deep, high-resolution observations in the FIR-to-mm regime. They…
Larger sizes of massive quiescent early-type galaxies in clusters than in the field at 0.8 < z < 1.5
L. Delaye, M. Huertas-Company, S. Mei +13
[abridged] The mass-size relation of early-type galaxies (ETGs) has been largely studied in the last years to probe the mass assembly of the most massive objects in the Universe. I…
Scaling Relations and Overabundance of Massive Clusters at z>~1 from Weak-Lensing Studies with HST
M. J. Jee, K. S. Dawson, H. Hoekstra +22
We present weak gravitational lensing analysis of 22 high-redshift (z >~1) clusters based on Hubble Space Telescope images. Most clusters in our sample provide significant lensing…
A lack of LAEs within 5Mpc of a luminous quasar in an overdensity at z=6.9: potential evidence of quasar negative feedback at protocluster scales
Trystan S. Lambert, R. J. Assef, C. Mazzucchelli +13
High-redshift quasars are thought to live in the densest regions of space which should be made evident by an overdensity of galaxies around them. However, campaigns to identify the…
