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: Savdeep Sethi | First 5 Authors: Savdeep Sethi, , , , | Summary: I suggest the possibility of a new string in ten dimensions. Evidence for this string is presented both from orientifold physics and from K-theory, along with a mystery concerning the M-theory description. Motivated by this possibility, some novel aspects of […]
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: Juan I. Collar | First 5 Authors: J. I. Collar, , , , | Summary: A new experimental evaluation of the quenching factor for nuclear recoils in NaI[Tl] is described. Systematics affecting previous measurements are addressed by careful characterization of the emission spectrum of the neutron source, use of a small scintillator coupled […]
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: Andrey V. Kravtsov | First 5 Authors: Andrey V. Kravtsov, , , , | Summary: Sizes of galaxies are an important diagnostic for galaxy formation models. In this study I use the abundance matching ansatz, which has proven to be successful in reproducing galaxy clustering and other statistics, to derive estimates of the […]
Kavli Affiliate: Bradford Benson | First 5 Authors: Michael McDonald, Bradford Benson, Sylvain Veilleux, Marshall W. Bautz, Christian L. Reichardt | Summary: We present Hubble Space Telescope Wide Field Camera 3 observations of the core of the Phoenix Cluster SPT-CLJ2344-4243 in five broadband filters spanning rest-frame 1000–5500A. These observations reveal complex, filamentary blue emission, extending […]
