Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, , , , | Summary: Cluster number counts offer sensitive probes of the dark energy if and only if the_evolution_ of the cluster mass versus observable relation(s) is well calibrated. We investigate the potential for internal calibration by demanding consistency in the counts as a […]
Kavli Affiliate: Robert Wood | First 5 Authors: Gad Getz, Hilah Gal, Itai Kela, Eytan Domany, Dan A. Notterman | Summary: We present and review Coupled Two Way Clustering, a method designed to mine gene expression data. The method identifies submatrices of the total expression matrix, whose clustering analysis reveals partitions of samples (and genes) […]
Kavli Affiliate: Richard D. Robinson | First 5 Authors: Richard D. Robinson, Myron A. Smith, Gregory W. Henry, , | Summary: gamma Cas (B0.5e) is known to be a unique X-ray source because ot its moderate L_x, hard X-ray spectrum, and light curve punctuated by ubiquitous flares and slow undulations. Its X-ray peculiarities have led […]
Kavli Affiliate: Robert Rosner | First 5 Authors: Alexandros Alexakis, Yuan-Nan Young, Robert Rosner, , | Summary: We study the weakly non-linear development of shear-driven gravity waves, and investigate the mixing properties of the finite amplitude solutions. Calculations to date have been restricted to the linear theory, which predicts that gravity waves are amplified by […]
Kavli Affiliate: Wendy Freedman | First 5 Authors: Wendy L. Freedman, , , , | Summary: New, large, ground and space telescopes are contributing to an exciting and rapid period of growth in observational cosmology. The subject is now far from its earlier days of being data-starved and unconstrained, and new data are fueling a […]
Kavli Affiliate: Daniel S. Akerib | First 5 Authors: Daniel S. Akerib, Sean M. Carroll, Marc Kamionkowski, Steven Ritz, | Summary: The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. […]
Kavli Affiliate: Yukari Ito | First 5 Authors: Yukari Ito, , , , | Summary: There are many generalizations of the McKay correspondence for higher dimensional Gorenstein quotient singularities and there are some applications to compute the topological invariants today. But some of the invariants are completely different from the classical invariants, in particular for […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Jonathan L. Rosner, , , , | Summary: An elementary description of CP violation for the non-specialist is presented. This article, for publication in {it Macmillan Encylopedia of Physics, Supplement: Elementary Particle Physics}, is being submitted to the Archive for comments by colleagues. | Search Query: […]
Kavli Affiliate: Claude Canizares | First 5 Authors: David Huenemoerder, Claude Canizares, Kevin Tibbetts, , | Summary: We observed AR Lac, an eclipsing RS CVn binary star, with the Chandra High Energy Grating Spectrometer for a total of 100 ks divided into six intervals covering both quadratures and eclipses. We repeated observations at each phase. […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Hale Bradt, Alan M. Levine, Francis E. Marshall, Ronald A. Remillard, Donald A. Smith | Summary: The role of the Rossi X-ray Timing Explorer (RXTE) in the study of Gamma-ray Bursts (GRBs) is reviewed. Through April 2001, the All-Sky Monitor (ASM) and the Proportional Counter Array (PCA) […]
