The DES view of the Eridanus supervoid and the CMB Cold Spot
A. Kovács, N. Jeffrey, M. Gatti +119
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground str…
Combining Planck and SPT cluster catalogs: cosmological analysis and impact on Planck scaling relation calibration
L. Salvati, A. Saro, S. Bocquet +41
We provide the first combined cosmological analysis of South Pole Telescope (SPT) and Planck cluster catalogs. The aim is to provide an independent calibration for Planck scaling r…
Improving cosmological constraints from galaxy cluster number counts with CMB-cluster-lensing data: Results from the SPT-SZ survey and forecasts for the future
P. S. Chaubal, C. L. Reichardt, N. Gupta +40
We show the improvement to cosmological constraints from galaxy cluster surveys with the addition of CMB-cluster lensing data. We explore the cosmological implications of adding ma…
Vacuum Energy Density Measured from Cosmological Data
J. Prat, C. Hogan, C. Chang +1

S. Pandey, M. Gatti, E. Baxter +121
Hot, ionized gas leaves an imprint on the cosmic microwave background via the thermal Sunyaev Zel'dovich (tSZ) effect. The cross-correlation of gravitational lensing (which traces…
Dark Energy Survey Year 3 results: Galaxy-halo connection from galaxy-galaxy lensing
G. Zacharegkas, C. Chang, J. Prat +114
Galaxy-galaxy lensing is a powerful probe of the connection between galaxies and their host dark matter halos, which is important both for galaxy evolution and cosmology. We extend…
