We present Magellan/IMACS spectroscopy of three recently discovered ultra-faint Milky Way satellites, Grus II, Tucana IV, and Tucana V. We measure systemic velocities of V_hel = -1…
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…
STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354
A. J. Shajib, S. Birrer, T. Treu +88
We present a blind time-delay cosmographic analysis for the lens system DES J04085354. This system is extraordinary for the presence of two sets of multiple images at different…
The SPTpol Extended Cluster Survey

We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
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…
