Dark Energy Tomography
Yong-Seon Song, Lloyd Knox
We study how parameter error forecasts for tomographic cosmic shear observations are affected by sky coverage, density of source galaxies, inclusion of CMB experiments, simultaneou…
Effects of sub-mm and radio point sources on the recovery of Sunyaev-Zeldovich galaxy cluster parameters
Lloyd Knox, Gil Holder, Sarah Church
Observations of clusters in the 30 to 350 GHz range can in principle be used to determine a galaxy cluster's Comptonization parameter, y, peculiar velocity, v and gas temperature,…
COMPASS: An Upper Limit on CMB Polarization at an Angular Scale of 20 arc minutes
Philip C. Farese, Giorgio Dall'Oglio, Joshua O. Gundersen +10
COMPASS is an on-axis 2.6 meter telescope coupled to a correlation polarimeter operating at a wavelength of 1 cm. The entire instrument was built specifically for CMB polarization…
CMB Likelihood Functions for Beginners and Experts
Andrew H. Jaffe, J. R. Bond, P. G. Ferreira +1
Although the broad outlines of the appropriate pipeline for cosmological likelihood analysis with CMB data has been known for several years, only recently have we had to contend wi…
COMPASS: An Instrument for Measuring the Polarization of the CMB on Intermediate Angular Scales
Philip C. Farese, Giorgio Dall'Oglio, Josh Gundersen +9
COMPASS is an on-axis 2.6 meter telescope coupled to a correlation polarimeter. The entire instrument was built specifically for CMB polarization studies. Careful attention was giv…
The Spectrum of Integrated Millimeter Flux of the Magellanic Clouds and 30-Doradus from TopHat and DIRBE Data
J. E. Aguirre, J. J. Bezaire, E. S. Cheng +10
We present measurements of the integrated flux relative to the local background of the Large and Small Magellanic Clouds and the region 30-Doradus (the Tarantula Nebula) in the LMC…
