Kavli Affiliate: Mark Vagins | First 5 Authors: LBNE Collaboration, Corey Adams, David Adams, Tarek Akiri, Tyler Alion | Summary: The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay — these mysteries at the forefront […]
Kavli Affiliate: Alan Levine | First 5 Authors: Saul Rappaport, Roberto Sanchis-Ojeda, Leslie A. Rogers, Alan Levine, Joshua N. Winn | Summary: The requirement that a planet must orbit outside of its Roche limit gives a lower limit on the planet’s mean density. The minimum density depends almost entirely on the orbital period and is […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Henrique S. Xavier, Ravi R. Gupta, Masao Sako, Chris B. D’Andrea, Joshua A. Frieman | Summary: We used the GMBCG galaxy cluster catalogue and SDSS-II supernovae data with redshifts measured by the BOSS project to identify 48 SNe Ia residing in rich galaxy clusters and compare […]
Kavli Affiliate: Erotokritos Katsavounidis | First 5 Authors: Rahul Biswas, Lindy Blackburn, Junwei Cao, Reed Essick, Kari Alison Hodge | Summary: The sensitivity of searches for astrophysical transients in data from the LIGO is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, P. A. R. Ade, N. Aghanim, C. Armitage-Caplan, M. Arnaud | Summary: We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating […]
Kavli Affiliate: Toshitake Kohno | First 5 Authors: Toshitake Kohno, Andrei Pajitnov, , , | Summary: Let X be a finite CW-complex, denote its fundamental group by G. Let R be an n-dimensional complex repesentation of G. Any element A of the first cohomology group of X with complex coefficients gives rise to the exponential […]
Kavli Affiliate: John W. Belcher | First 5 Authors: Richard H. Price, John W. Belcher, David A. Nichols, , | Summary: We compare the nature of electromagnetic fields and of gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In particular the "lines of force" visualizations of electromagnetism are […]
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 […]
