摘要:

亚毫米波长区域也许是大面积天空中探索最少的区域,尽管在绘制小区域的深度图方面已经花费了相当大的努力。因此,整个亚毫米天空的性质,特别是罕见的明亮天体的性质,在很大程度上仍然是未知的。在这里,我们描述了一个即将到来的调查(SCUBA-2“全天空”调查,或SASSy),旨在解决这个问题,通过制作一个大面积的地图,约五分之一的天空可见从JCMT(4800平方度)下降到1西格玛噪声水平为30 mJy/梁。这张地图形成了一个更大的调查的试点,这将有可能绘制从JCMT可见的剩余天空,该地区也是ALMA可见的优先事项。SASSy已被授予4800平方度试点阶段的500小时,并将在SCUBA-2调试后开始,预计在2008年初。

英文摘要:

The sub-millimetre wavelength regime is perhaps the most poorly explored over large areas of the sky, despite the considerable effort that has been expended in making deep maps over small regions. As a consequence the properties of the sub-millimetre sky as a whole, and of rare bright objects in particular, remains largely unknown. Here we describe a forthcoming survey (the SCUBA-2 ``All-Sky'' Survey, or SASSy) designed to address this issue by making a large-area map of approximately one-fifth of the sky visible from the JCMT (4800 square degrees) down to a 1 sigma noise level of 30 mJy/beam. This map forms the pilot for a much larger survey, which will potentially map the remaining sky visible from the JCMT, with the region also visible to ALMA as a priority. SASSy has been awarded 500 hours for the 4800 square degree pilot phase and will commence after the commissioning of SCUBA-2, expected in early 2008.
