MAD-4-MITO, a multi array of detectors for ground-based mm/submm SZ observations

Abstract

The last few years have seen a large development of mm technology and ultra-sensitive detectors devoted to microwave astronomy and astrophysics. The possibility to deal with large numbers of these detectors assembled into multi-pixel imaging systems has greatly improved the performance of microwave observations, even from ground-based stations, especially combining the power of multi-band detectors with their new imaging capabilities. Hereafter, we will present the development of a multi-pixel solution devoted to Sunyaev-Zel'dovich observations from ground-based telescopes, that is going to be operated from the Millimetre and Infrared Testagrigia Observatory.

“…1 − 3 can be critically tested against more precise spectral SZE measurements of A2163 in the frequency bands of ∼ 50 − 130GHz and ∼ 300 − 600GHz by MAX, MSAM and SuZIE types of experiments in the frequency passbands of 90 − 670GHz and by AMiBA in the band 84 − 104GHz, Nobeyama at 21 and 43GHz, JCMT at 350 and 650GHz, SZA in the bands of 26 − 36GHz and 85 − 115GHz, BIMA and OVRO in the band of 26−36GHz, MINT at 150GHz and ACT at 150, 220, and 270 GHz. Multi-frequency projects such as the upgraded MITO (Lamagna et al 2002;De Petris et al 2002) and the OLIMPO (Masi et al 2003) experiments are very promising to provide some results.…”
