Blinding multi-probe cosmological experiments
J. Muir, G. M. Bernstein, D. Huterer +62
The goal of blinding is to hide an experiment's critical results -- here the inferred cosmological parameters -- until all decisions affecting its analysis have been finalised. Thi…
Dark Energy Survey Year 1 Results: the lensing imprint of cosmic voids on the Cosmic Microwave Background
P. Vielzeuf, A. Kovács, U. Demirbozan +62
Cosmic voids gravitationally lens the cosmic microwave background (CMB) radiation, resulting in a distinct imprint on degree scales. We use the simulated CMB lensing convergence ma…

Trans-Neptunian objects found in the first four years of the Dark Energy Survey
Pedro H. Bernardinelli, Gary M. Bernstein, Masao Sako +61
We present a catalog of 316 trans-Neptunian bodies detected by the Dark Energy Survey (DES). These objects include 245 discoveries by DES (139 not previously published) detected in…
Dark Energy Survey Year 1 results: The relationship between mass and light around cosmic voids
Y. Fang, N. Hamaus, B. Jain +74
What are the mass and galaxy profiles of cosmic voids? In this paper we use two methods to extract voids in the Dark Energy Survey (DES) Year 1 redMaGiC galaxy sample to address th…
Detection of cross-correlation between gravitational lensing and gamma rays
S. Ammazzalorso, D. Gruen, M. Regis +75
In recent years, many gamma-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-corr…
