Kavli Affiliate: Rafe Schindler | First 5 Authors: Qian Yang, Yue Shen, Yu-Ching Chen, Xin Liu, James Annis | Summary: We present new Gemini/GMOS optical spectroscopy of 16 extreme variability quasars (EVQs) that dimmed by more than 1.5 mag in the $g$ band between the Sloan Digital Sky Survey (SDSS) and the Dark Energy Survey […]
Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Keith Bechtol, Alex Drlica-Wagner, Kevork N. Abazajian, Muntazir Abidi, Susmita Adhikari | Summary: Astrophysical observations currently provide the only robust, empirical measurements of dark matter. In the coming decade, astrophysical observations will guide other experimental efforts, while simultaneously probing unique regions of dark matter parameter space. […]
Kavli Affiliate: Rafe Schindler | First 5 Authors: Joseph DeRose, Risa H. Wechsler, Matthew R. Becker, Michael T. Busha, Eli S. Rykoff | Summary: We present a suite of 18 synthetic sky catalogs designed to support science analysis of galaxies in the Dark Energy Survey Year 1 (DES Y1) data. For each catalog, we use […]
Kavli Affiliate: Rafe Schindler | First 5 Authors: Pierandrea Guarnieri, Claudia Maraston, Daniel Thomas, Janine Pforr, Violeta Gonzalez-Perez | Summary: Using stellar population models, we predicted that the Dark Energy Survey (DES) – due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) – would be in the position to […]
Kavli Affiliate: Philip H. Scherrer | First 5 Authors: Sahil Hegde, Monica G. Bobra, Philip H. Scherrer, , | Summary: Solar activity, such as flares, produce bursts of high-energy radiation that temporarily enhance the D-region of the ionosphere and attenuate low-frequency radio waves. To track these Sudden Ionospheric Disturbances (SIDs), which disrupt communication signals and […]
Kavli Affiliate: Patricia Burchat | First 5 Authors: The LSST Dark Energy Science Collaboration, Rachel Mandelbaum, Tim Eifler, Renée Hložek, Thomas Collett | Summary: The Large Synoptic Survey Telescope (LSST) Dark Energy Science Collaboration (DESC) will use five cosmological probes: galaxy clusters, large scale structure, supernovae, strong lensing, and weak lensing. This Science Requirements Document […]
Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Alexander Madurowicz, Bruce A. Macintosh, Jean-Baptiste Ruffio, Jeffery Chilcote, Vanessa P. Bailey | Summary: A semi analytic framework for simulating the effects of atmospheric seeing in Adaptive Optics systems on an 8-m telescope is developed with the intention of understanding the origin of the wind-butterfly, a […]
Kavli Affiliate: Paul Brink | First 5 Authors: Robert Agnese, Taylor Aralis, Tsuguo Aramaki, Isaac Arnquist, Elham Azadbakht | Summary: The Super Cryogenic Dark Matter Search experiment (SuperCDMS) at the Soudan Underground Laboratory studied energy loss associated with Frenkel defect formation in germanium crystals at mK temperatures using in situ $^{210}$Pb sources. We examine the […]

Kavli Affiliate: Philip H. Scherrer | First 5 Authors: M. Cristina Rabello-Soares, Richard S. Bogart, Philip H. Scherrer, , | Summary: We analyze the effect of a sunspot in its quiet surroundings applying a helioseismic technique on almost three years of Helioseismic and Magnetic Imager (HMI) observations obtained during solar cycle 24 to further study […]
