Kavli Affiliate: Peter Michelson | First 5 Authors: Roger W. Romani, David Sowards-Emmerd, Lincoln Greenhill, Peter Michelson, | Summary: We report the discovery of a radio-loud flat-spectrum QSO at z=5.47 with properties similar to those of the EGRET gamma-ray blazars. This source is the brightest radio QSO at z>5, with a pc-scale radio jet and […]
Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, , , , | Summary: A direct comparison of quantum and classical dynamical systems can be accomplished through the use of distribution functions. This is useful for both fundamental investigations such as the nature of the quantum-classical transition as well as for applications such as […]
Kavli Affiliate: Luca Grandi | First 5 Authors: R. Brunetti, E. Calligarich, M. Cambiaghi, F. Carbonara, A. Cocco | Summary: The WARP programme is a graded programme intended to search for cold Dark Matter in the form of WIMP’s. These particles may produce via weak interactions nuclear recoils in the energy range 10-100 keV. A […]
Kavli Affiliate: Bradford Benson | First 5 Authors: B. A. Benson, P. A. R. Ade, J. J. Bock, K. M. Ganga, C. N. Henson | Summary: We present new measurements of the Sunyaev-Zel’dovich (SZ) effect from clusters of galaxies using the Sunyaev-Zel’dovich Infrared Experiment (SuZIE II). We combine these new measurements with previous cluster observations […]
Kavli Affiliate: George W. Clark | First 5 Authors: George W. Clark, , , , | Summary: Properties of the X-ray halo of the eclipsing X-ray pulsar 4U 1538-52 are derived from a 25 ksec observation by the Chandra X-Ray Observatory. Profiles of the halo, compiled in two energy ranges, 2 to 4 keV and […]
Kavli Affiliate: Liantao Wang | First 5 Authors: Dan Hooper, Lian-Tao Wang, , , | Summary: Recently, the SPI spectrometer on the INTEGRAL satellite observed strong 511 keV line emission from the galactic bulge. Although the angular distribution (spherically symmetric with width of sim 9 degree) of this emission is difficult to account for with […]
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 […]
