Kavli Affiliate: Stuart Marshall | First 5 Authors: Alastair Murray, Stuart Marshall, Leroy Cronin, , | Summary: How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based […]
Kavli Affiliate: Philip H. Scherrer | First 5 Authors: J. Todd Hoeksema, Charles S. Baldner, Rock I. Bush, Jesper Schou, Philip H. Scherrer | Summary: The Helioseismic and Magnetic Imager (HMI) instrument is a major component of NASA’s Solar Dynamics Observatory (SDO) spacecraft. Since beginning normal science operations on 1 May 2010, HMI has operated […]
Kavli Affiliate: Steven Kahn | First 5 Authors: Jason Rhodes, Robert C. Nichol, Éric Aubourg, Rachel Bean, Dominique Boutigny | Summary: Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high cadence, deep, wide-field optical photometry from LSST with high […]
Kavli Affiliate: Ralf Kaehler | First 5 Authors: Ralf Kaehler, , , , | Summary: This paper presents an accurate density computation approach for large dark matter simulations, based on a recently introduced phase-space tessellation technique and designed for massively parallel, heterogeneous cluster architectures. We discuss a memory efficient construction of an oct-tree structure to […]
Kavli Affiliate: Paul Brink | First 5 Authors: Noah Kurinsky, Paul Brink, Richard Partridge, Blas Cabrera, Matt Pyle | Summary: We present the technical design for the SuperCDMS high-voltage, low-mass dark matter detectors, designed to be sensitive to dark matter down to 300 MeV/$c^2$ in mass and resolve individual electron-hole pairs from low-energy scattering events […]
Kavli Affiliate: Philip Marshall | First 5 Authors: Lindsay Oldham, Matt Auger, Chris Fassnacht, Tommaso Treu, Brendon J. Brewer | Summary: We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NIRC2, we model the surface brightness distributions and […]
Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa, Makoto Uemura, Yasuyuki T. Tanaka | Summary: Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energies […]
Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Vanessa P. Bailey, Lisa A. Poyneer, Bruce A. Macintosh, Dmitry Savransky, Jason J. Wang | Summary: The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science data and AO telemetry […]
Kavli Affiliate: Daniel Akerib | First 5 Authors: Jim Alexander, Marco Battaglieri, Bertrand Echenard, Rouven Essig, Matthew Graham | Summary: This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the status of this […]
Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu, Fumie Akimoto, Steven W. Allen | Summary: High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of various massive systems, such as galaxies and […]
