Kavli Affiliate: David Charbonneau | First 5 Authors: David Charbonneau, , , , | Summary: I present a review of observational efforts to study known extrasolar planets by methods that are complementary to the radial velocity technique. I describe the current state of attempts to detect and characterize such planets by astrometry, by reflected light, […]
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 […]
