Kavli Affiliate: Ralf Kaehler | First 5 Authors: Ralf Kaehler, Tom Abel, , , | Summary: Structured Adaptive Mesh Refinement (SAMR) is a popular numerical technique to study processes with high spatial and temporal dynamic range. It reduces computational requirements by adapting the lattice on which the underlying differential equations are solved to most efficiently […]
Kavli Affiliate: Ralf Kaehler | First 5 Authors: Oliver Hahn, Tom Abel, Ralf Kaehler, , | Summary: Recently, we have shown how current cosmological N-body codes already follow the fine grained phase-space information of the dark matter fluid. Using a tetrahedral tesselation of the three-dimensional manifold that describes perfectly cold fluids in six-dimensional phase space, […]
Kavli Affiliate: Homer Neal | First 5 Authors: Z. Akopov, Silvia Amerio, David Asner, Eduard Avetisyan, Olof Barring | Summary: Data from high-energy physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of […]
Kavli Affiliate: Robert A. Cameron | First 5 Authors: Markos Trichas, Paul J. Green, John D. Silverman, Tom Aldcroft, Wayne Barkhouse | Summary: From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic follow up using the FLWO, […]
Kavli Affiliate: Sarah Church | First 5 Authors: Matthew Sieth, Sarah Church, Judy M. Lau, Patricia Voll, Todd Gaier | Summary: We report on the development of W-band (75-110 GHz) heterodyne receiver technology for large-format astronomical arrays. The receiver system is designed to be both mass-producible, so that the designs could be scaled to thousands […]
Kavli Affiliate: Tomasz Biesiadzinski | First 5 Authors: Michael Schubnell, Tomasz Biesiadzinski, Wolfgang Lorenzon, Robert Newman, Greg Tarle | Summary: Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reciprocity failure over the full dynamic range of near infrared […]
Kavli Affiliate: Robert A. Cameron | First 5 Authors: Robert A. Cameron, , , , | Summary: We present the prospects for a future joint gamma-ray and radio survey of southern hemisphere sources using the Fermi Large Area Telescope (LAT) and the upcoming Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. ASKAP is a next […]
Kavli Affiliate: Stuart Marshall | First 5 Authors: Željko Ivezić, Steven M. Kahn, J. Anthony Tyson, Bob Abel, Emily Acosta | Summary: (Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, […]
