Kavli Affiliate: John Carlstrom | First 5 Authors: J. E. Carlstrom, J. Kovac, E. M. Leitch, C. Pryke, | Summary: We review the current status and future plans for polarization measurements of the cosmic microwave background radiation, as well as the cosmology these measurements will address. After a long period of increasingly sensitive upper limits, […]
Kavli Affiliate: P. C. Joss | First 5 Authors: J. Madej, M. Pietrachowicz, P. C. Joss, A. Majczyna, A. Rozanska | Summary: We explore photometric properties of hypothetical iron core white dwarfs and compute their expected colors in UBVRI Johnson broadband system. Atmospheres of iron core WDs in this paper consist of pure iron covered […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Michael D. Gladders, Henk Hoekstra, H. K. C. Yee, Patrick B. Hall, L. Felipe Barrientos | Summary: The incidence of giant arcs due to strong-lensing clusters of galaxies is known to be discrepant with current theoretical expectations. This result derives from a comparison of several cluster samples […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Andrey V. Kravtsov, , , , | Summary: One of the most puzzling properties of observed galaxies is the universality of the empirical correlation between the star formation rate and average gas surface density on kiloparsec scales (the Schmidt law). In this study I present results […]
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. […]
