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…
Categorizing models using Self-Organizing Maps: an application to modified gravity theories probed by cosmic shear
Agnès Ferté, Shoubaneh Hemmati, Daniel Masters +4
We propose to use Self-Organizing Maps (SOM) to map the impact of physical models onto observables. Using this approach, we are be able to determine how theories relate to each oth…
Constraining Gravity with a -cut Cosmic Shear Analysis of the Hyper Suprime-Cam First-Year Data
Leah Vazsonyi, Peter L. Taylor, Georgios Valogiannis +3
Using Subaru Hyper Suprime-Cam (HSC) year 1 data, we perform the first -cut cosmic shear analysis constraining both CDM and Hu-Sawicki modified gravity. To generate th…

DES Collaboration, T. M. C. Abbott, M. Aguena +108
We present angular diameter measurements obtained by measuring the position of Baryon Acoustic Oscillations (BAO) in an optimised sample of galaxies from the first three years of D…
Dark Energy Survey Year 3 Results: Galaxy mock catalogs for BAO analysis
I. Ferrero, M. Crocce, I. Tutusaus +83
The calibration and validation of scientific analysis in simulations is a fundamental tool to ensure unbiased and robust results in observational cosmology. In particular, mock gal…
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…
