Measurements of Secondary Cosmic Microwave Background Anisotropies with the South Pole Telescope
M. Lueker, C. L. Reichardt, K. K. Schaffer +40
We report cosmic microwave background (CMB) power spectrum measurements from the first 100 sq. deg. field observed by the South Pole Telescope (SPT) at 150 and 220 GHz. On angular…
Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
Angular Power Spectra of the Millimeter Wavelength Background Light from Dusty Star-forming Galaxies with the South Pole Telescope
N. R. Hall, L. Knox, C. L. Reichardt +41
We use data from the first 100 square-degree field observed by the South Pole Telescope (SPT) in 2008 to measure the angular power spectrum of temperature anisotropies contributed…
Non-Gaussianity from false vacuum inflation: Old curvaton scenario
Jinn-Ouk Gong, Chunshan Lin, Yi Wang
We calculate the three-point correlation function of the comoving curvature perturbation generated during an inflationary epoch driven by false vacuum energy. We get a novel false…
Extragalactic millimeter-wave sources in South Pole Telescope survey data: source counts, catalog, and statistics for an 87 square-degree field
J. D. Vieira, T. M. Crawford, E. R. Switzer +52
We report the results of an 87 square-degree point-source survey centered at R.A. 5h30m, decl. -55 deg. taken with the South Pole Telescope (SPT) at 1.4 and 2.0 mm wavelengths with…
Probing interaction and spatial curvature in the holographic dark energy model
Miao Li, Xiao-Dong Li, Shuang Wang +2
In this paper we place observational constraints on the interaction and spatial curvature in the holographic dark energy model. We consider three kinds of phenomenological interact…
