摘要

对光学昏暗的类星体进行频率空间的毫米波段扫描可能是一种检测新的高红移分子吸收系统的高效方法。在这里，我们描述了对7个类星体在宽带宽(高达23 GHz)上的扫描，其灵敏度限制足以探测到已知的4个红移吸收器。有了更宽的频带，对大量可能被遮挡的物体的高效搜索将产生许多新的分子吸收剂。

Deep Searches for High Redshift Molecular Absorption

Millimetre-band scans of the frequency space towards optically dim quasars is potentially a highly efficient method for detecting new high red-shift molecular absorption systems. Here we describe scans towards 7 quasars over wide bandwidths (up to 23 GHz) with sensitivity limits sufficient to detect the 4 redshifted absorbers already known. With wider frequency bands, highly efficient searches of large numbers of possibly obscured objects will yield many new molecular absorbers.
