First Cosmology Results Using Type Ia Supernovae From the Dark Energy Survey: Photometric Pipeline and Light Curve Data Release
D. Brout, M. Sako, D. Scolnic +89
We present griz light curves of 251 Type Ia Supernovae (SNe Ia) from the first 3 years of the Dark Energy Survey Supernova Program's (DES-SN) spectroscopically classified sample. T…
Dark Energy Survey Year 1 Results: Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
T. M. C. Abbott, F. B. Abdalla, A. Alarcon +164
We perform a joint analysis of the auto and cross-correlations between three cosmic fields: the galaxy density field, the galaxy weak lensing shear field, and the cosmic microwave…
Dark Energy Survey Year 1 Results: Measurement of the Galaxy Angular Power Spectrum
H. Camacho, N. Kokron, F. Andrade-Oliveira +73
We use data from the first-year (Y1) observations of the DES collaboration to measure the galaxy angular power spectrum (APS), and search for its BAO feature using a template-fitti…
Exploring the Very Extended Low Surface Brightness Stellar Populations of the Large Magellanic Cloud with SMASH
David L. Nidever, Knut Olsen, Yumi Choi +23
We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R~21 degrees, or ~18.5 kpc at the LMC distance of 50 kpc, as detected i…
Discovery and Dynamical Analysis of an Extreme Trans-Neptunian Object with a High Orbital Inclination
J. C. Becker, T. Khain, S. J. Hamilton +62
We report the discovery and dynamical analysis of 2015 BP, an extreme Trans-Neptunian Object detected detected by the Dark Energy Survey at a heliocentric distance of 55 AU…
Survey geometry and the internal consistency of recent cosmic shear measurements
M. A. Troxel, E. Krause, C. Chang +76
We explore the impact of an update to the typical approximation for the shape noise term in the analytic covariance matrix for cosmic shear experiments that assumes the absence of…
