Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Ariel Megevand, Mariano Quiros, Carlos E. M. Wagner, | Summary: New fermions, strongly coupled to the Standard Model Higgs boson provide a well motivated extension of the Standard Model (SM). In this work we show that, once new physics at heavier scales is added to […]
Kavli Affiliate: John Carlstrom | First 5 Authors: Erik M. Leitch, J. M. Kovac, N. W. Halverson, J. E. Carlstrom, C. Pryke | Summary: We present the analysis of the complete 3-year data set obtained with the Degree Angular Scale Interferometer (DASI) polarization experiment, operating from the Amundsen-Scott South Pole research station. Additional data obtained […]
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: 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: 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 […]
