The South Pole Telescope: A white paper for the Dark Energy Task Force
1 Overview The primary goal of the South Pole Telescope (SPT) project is to set constraints on the nature of dark energy by measuring its impact on the growth of structure, specifically the evolution of the number density of massive galaxy clusters. The SPT will conduct a deep, large solid angle (4000 deg) galaxy cluster survey by exploiting the redshift-independence of the Sunyaev-Zel’dovich E...
متن کاملA Measurement of the Secondary-cmb and Millimeter-wave-foreground Bispectrum Using 800 Square Degrees of South Pole Telescope Data
We present a measurement of the angular bispectrum of the millimeter-wave sky in observing bands centered at roughly 95, 150, and 220 GHz, on angular scales of 1 . θ . 10 (multipole number 1000 . l . 10,000). At these frequencies and angular scales, the main contributions to the bispectrum are expected to be the thermal Sunyaev-Zel’dovich (tSZ) effect and emission from extragalactic sources, pr...
متن کاملA Submillimetre Imaging Polarimeter at the James Clerk Maxwell Telescope
A polarimeter has been built for use with the Submillimetre Common-User Bolometer Array (SCUBA), on the James Clerk Maxwell Telescope (JCMT) in Hawaii. SCUBA is the first of a new generation of highly sensitive submillimetre cameras, and the UK/Japan Polarimeter adds a polarimetric imaging/photometry capability in the wavelength range 350 to 2000 μm. Early science results range from measuring t...
متن کاملSPTpol: an instrument for CMB polarization measurements with the South Pole Telescope
SPTpol is a dual-frequency polarization-sensitive camera that was deployed on the 10-meter South Pole Telescope in January 2012. SPTpol will measure the polarization anisotropy of the cosmic microwave background (CMB) on angular scales spanning an arcminute to several degrees. The polarization sensitivity of SPTpol will enable a detection of the CMB “B-mode” polarization from the detection of t...
متن کاملPolarimeter Receiver Prototyping and Testing for the South Pole Telescope Upgrade
Experimental evidence has so far been supportive for the inflationary Big Bang model of cosmology, while imposing other mysteries, such as the fact that dark matter and dark energy actually consist of 95% of the observable universe. The forthcoming upgrade of the South Pole Telescope, planned for 2010, will include a polarimeter with increased sensitivity. Measurements of the CMB polarization a...
