摘要:

我们描述了一个试点调查与Mopra 22米射电望远镜在90 GHz(MALT 90)毫米天文遗产团队调查的准备。我们确定了182个候选人密集的分子团,使用六种不同的选择标准,并映射每个源同时在16个不同的线90 GHz附近。我们提出了一个总结的数据,并描述了如何试点调查的结果形成了更大的MALT 90调查的设计。我们激励我们选择的目标源的主要调查的基础上,试点检测率,并展示了在多条线同时在高光谱分辨率映射的价值。

英文摘要:

We describe a pilot survey conducted with the Mopra 22-m radio telescope in preparation for the Millimeter Astronomy Legacy Team Survey at 90 GHz (MALT90). We identified 182 candidate dense molecular clumps using six different selection criteria and mapped each source simultaneously in 16 different lines near 90 GHz. We present a summary of the data and describe how the results of the pilot survey shaped the design of the larger MALT90 survey. We motivate our selection of target sources for the main survey based on the pilot detection rates and demonstrate the value of mapping in multiple lines simultaneously at high spectral resolution.
