Cosmology from BOLOCAM Observations of Arcminute-Scale Anisotropy in the Cosmic Microwave Background

AST-0098737Lange，A.E.该计划将使用Bolocam，一种高通量、多波长、毫米波相机，设计用于在1.1 mm、1.4 mm和2.1 mm的空间运行，以拍摄天空中重要区域上宇宙微波背景(CMB)的弧分尺度各向异性。使用加州理工大学亚毫米天文台(CSO)的Bolocam相机，将有可能测量1平方度的天空。这项调查将通过太阳热效应(SZE)探测100个星系团。此外，它还将在4000至8000的多极矩(1.5至3角分的角度尺度)下测量次级CMB各向异性(由于与视线上的大尺度结构有关的热Sze的波动)的功率谱。通过选择与SIRTF MIPS团队的深度保证时间观测目标场一致的目标场，将最大限度地发挥这些观测的效用。除了相对自由的星系前景和来自SIRTF上的MIPS和IRAC的深度红外覆盖外，这些领域还包括XMM X射线卫星上的EPIC仪器预计的一些最深度的积分。

AST-0098737Lange, A.E.This program will use BOLOCAM, a high-throughput, multi-wavelength, mm-wave camera designed for operation at 1.1 mm, 1.4 mm, and 2.1 mm, to image the arcminute-scale anisotropy of the Cosmic Microwave Background (CMB) over significant areas of the sky. Using BOLOCAM at the Caltech Submillimeter Observatory (CSO), it will be possible to survey 1 square degree of sky. Such a survey would detect 100 clusters of galaxies via the thermal Sunyaev-Zeldovich effect (SZE). In addition, it would measure the power spectrum of secondary CMB anisotropy (due to fluctuations in the thermal SZE associated with large-scale structure along the line of sight) at multipole moments of 4000 to 8000 (angular scales of 1.5 to 3 arcminutes). The utility of these observations will be maximized by choosing the target fields to coincide with those targeted by the SIRTF MIPS team for their deep guaranteed-time observations. In addition to beingrelatively free of galactic foregrounds and having deep infrared coverage from the MIPS and IRAC on SIRTF, these fields include some of the deepest integrations expected from the EPIC instrument on the XMM X-ray satellite.***
