We study the effect of Faraday rotation due to a uniform magnetic field on the polarization of the cosmic microwave background. Scalar fluctuations give rise...

PublicationCOLDz: A High Space Density of Massive Dusty Starburst Galaxies ∼1 Billion Years after the Big Bang
We report the detection of CO(J = 2 → 1) emission from three massive dusty starburst galaxies at z > 5 through molecular line scans in the NSF's Karl G. Jansky...
PublicationDark Energy Survey Year 3 Results: Photometric Data Set for Cosmology
We describe the Dark Energy Survey (DES) photometric data set assembled from the first three years of science operations to support DES Year 3 cosmologic...
PublicationFirst Cosmology Results using Supernovae Ia from the Dark Energy Survey: Survey Overview, Performance, and Supernova Spectroscopy
We present details on the observing strategy, data-processing techniques, and spectroscopic targeting algorithms for the first three years of operation for the...
PublicationFitting of supernovae without dark energy
With data from Pantheon, we have at our disposal a sample of more than a 1000 supernovae Ia covering a wide range of redshifts with good precision. Here, we...
PublicationIs there Any Evidence for Integrated Sachs-Wolfe Signal in WMAP First Year Data?
We introduce a pixel-to-pixel comparison method to detect the temperature anisotropies on the Cosmic Microwave Background induced by the time variation of...
PublicationJoint Analysis of BICEP2/Keck Array and Planck Data
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg2 patch...

PublicationStellar Disk Truncations: HI Density and Dynamics
Using HI Nearby Galaxy Survey (THINGS) 21-cm observations of a sample of nearby (nearly face-on) galaxies we explore whether the stellar disk truncation...
