ATCA and CMB anisotropies | | Ravi Subrahmanyan

27 Aug 2001 | | Subject: | astro-ph | | Affiliation: | ATNF, Australia | | Abstract: | Australia Telescope Compact Array (ATCA) observations in sky regions selected to be low in foreground confusion have been used to infer limits on arcmin-scale CMB anisotropy in total intensity and polarization. These deep searches have, hitherto, been made using the East-West ATCA in an ultra-compact 1-D array configuration and in the highest available frequency band at 3-cm wavelength. The ATCA is being upgraded for operation at mm wavelengths and in 2-D array configurations: the enhanced capabilities present a new opportunity for pursuing CMB anisotropy related observations with reduced foreground confusion and at smaller angular scales. | | Source: | arXiv, astro-ph/0108409 | | Services: | Forum | Review | PDF | Favorites | |
