| Abstract: |
The Atacama Submillimeter Telescope Experiment (ASTE) is a joint project between Japan and Chile to install and operate a high-precision, 10m telescope in the Atacama desert for exploration of the southern sky in the sub-millimeter. Currently, we have achieved a main reflector surface accuracy of 19 μm (RMS) and a pointing accuracy of 1.″2 (RMS). A new 350 GHz cartridge-type receiver, installed in September 2004, shows good performance, with a typical system noise temperature of 200K (DSB1) and a main beam efficiency of up to 0.8 during winter nights. Four banks of 512MHz (or 128 MHz) width digital spectrometers with 1024 channels are available. Extensive submillimeter observations of various objects such as massive star forming regions in our Galaxy have been started with ASTE. |
