Dark Energy Survey Year 1 Results: Calibration of redMaGiC Redshift Distributions in DES and SDSS from Cross-Correlations

R. Cawthon, C. Davis, M. Gatti +88

We present calibrations of the redshift distributions of redMaGiC galaxies in the Dark Energy Survey Year 1 (DES Y1) and Sloan Digital Sky Survey (SDSS) DR8 data. These results det…

Dark Energy Survey Year 1 Results: Galaxy Sample for BAO Measurement

M. Crocce, A. J. Ross, I. Sevilla-Noarbe +84

We define and characterise a sample of 1.3 million galaxies extracted from the first year of Dark Energy Survey data, optimised to measure Baryon Acoustic Oscillations in the prese…

Dark Energy Survey Year 1 Results: Measurement of the Baryon Acoustic Oscillation scale in the distribution of galaxies to redshift 1

The Dark Energy Survey Collaboration, T. M. C. Abbott, F. B. Abdalla +109

We present angular diameter distance measurements obtained by locating the BAO scale in the distribution of galaxies selected from the first year of Dark Energy Survey data. We con…

DES meets Gaia: discovery of strongly lensed quasars from a multiplet search

A. Agnello, H. Lin, N. Kuropatkin +69

We report the discovery, spectroscopic confirmation and first lens models of the first two, strongly lensed quasars from a combined search in WISE and Gaia over the DES footprint.…

Dark Energy Survey Year 1 Results: A Precise H0 Measurement from DES Y1, BAO, and D/H Data

DES Collaboration, T. M. C. Abbott, F. B. Abdalla +88

We combine Dark Energy Survey Year 1 clustering and weak lensing data with Baryon Acoustic Oscillations (BAO) and Big Bang Nucleosynthesis (BBN) experiments to constrain the Hubble…

A gravitational-wave standard siren measurement of the Hubble constant

B. P. Abbott, R. Abbott, T. D. Abbott +1308

The detection of GW170817 in both gravitational waves and electromagnetic waves heralds the age of gravitational-wave multi-messenger astronomy. On 17 August 2017 the Advanced LIGO…

The Complete Light-curve Sample of Spectroscopically Confirmed Type Ia Supernovae from Pan-STARRS1 and Cosmological Constraints from The Combined Pantheon Sample

D. M. Scolnic, D. O. Jones, A. Rest +37

We present optical light curves, redshifts, and classifications for 365 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Surv…

Cosmological Perturbation Theory Using the FFTLog: Formalism and Connection to QFT Loop Integrals

Marko Simonović, Tobias Baldauf, Matias Zaldarriaga +2

We present a new method for calculating loops in cosmological perturbation theory. This method is based on approximating a CDM-like cosmology as a finite sum of complex power-la…

The Carnegie-Chicago Hubble Program. II. The Distance to IC 1613: The Tip of the Red Giant Branch and RR Lyrae Period-Luminosity Relations

Dylan Hatt, Rachael L. Beaton, Wendy L. Freedman +8

IC 1613 is an isolated dwarf galaxy within the Local Group. Low foreground and internal extinction, low metallicity, and low crowding make it an invaluable testbed for the calibrat…
