Atacama Compact Array Antennas
Masao Saito, Junji Inatani, Kouichiro Nakanishi +8
We report major performance test results of the Atacama Compact Array (ACA) 7-m and 12-m antennas of ALMA (Atacama Large Millimeter/submillimeter Array). The four major performance…
CO(1-0) imaging of M51 with CARMA and NRO45
J. Koda, T. Sawada, M. C. H. Wright +6
We report the CO(J=1-0) observations of M51 using both the Combined Array for Research in Millimeter Astronomy (CARMA) and the Nobeyama 45m telescope (NRO45). We describe a procedu…
Planck early results: first assessment of the High Frequency Instrument in-flight performance
Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six w…
Planck Early Results. II. The thermal performance of Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
The performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative…
Planck Early Results: The Planck mission
Planck Collaboration, P. A. R. Ade, N. Aghanim +272
The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009. Its performance is well in li…
