论文摘要
已知许多星系特性与星系嵌入的环境相关。它们的冷，中性气体含量通常通过21厘米HI观测来评估，与许多其他星系特性有关，因为它是恒星形成的潜在燃料。盲目的Arecibo Galaxy环境调查（AGES）调查凭借其高灵敏度和宽阔的天空覆盖范围，在广泛的环境中，从空隙到大型群集的核心，星系的HI性质的人口普查显着改善。在这里，我们向合并的集群Abell 1367和群集周围的大规模结构（LSS）提出了〜44000 mpc $^{3} $的hi人口普查。该调查敏感到n $ _ {hi} $ = 1.5 x 10 $^{17} $ cm $^{ - 2} $的列密度，用于发射光束和10 km/s的线宽度。作为一个近似质量敏感性限制，A1367的成员（在92 MPC的距离为92 MPC），其中包含M $ _ {HI} $ = 2.7x10 $^{8} $ M $ _ {\ odot} $在4 $ $σ$中以4 $ $ c的顶级宽度分布在50 km/s的顶部宽度上。将结果与来自SDS的光谱数据结合分析，我们用来根据Voronoi-Delaunay方法估算局部星系密度。我们总共检测到457个HI来源，其中213个是由AGES调查首次检测到的，其中134个是在本文中首次介绍。 225个检测在群集中，其余的体积中有232个。在这里，我们介绍了HI检测及其基本属性的完整目录，包括光学属性。我们专注于群集与前景和背景LS之间的差异，揭示了HI检测到的分数（和HI缺乏症）与局部星系密度的连续相关性，与全球环境无关。
Many galaxy properties are known to correlate with the environment in which the galaxies are embedded. Their cold, neutral gas content, usually assessed through 21cm HI observations, is related to many other galaxy properties as it is the underlying fuel for star formation. With its high sensitivity and broad sky coverage the blind Arecibo Galaxy Environment Survey (AGES) survey brings significant improvement to the census of HI properties of galaxies in a wide range of environments, from voids to the core of a massive cluster. Here we present an HI census over a volume of ~44000 Mpc$^{3}$ towards the merging cluster Abell 1367 and the large-scale structure (LSS) surrounding the cluster out to cz = 20000 km/s. The survey is sensitive down to a column density of N$_{HI}$ = 1.5 x 10$^{17}$ cm$^{-2}$ for emission filling the beam and a line width of 10 km/s. As an approximate mass sensitivity limit, a member of A1367 (at a distance of 92 Mpc), containing M$_{HI}$ = 2.7x10$^{8}$ M$_{\odot}$ distributed over a top-hat profile of 50 km/s width would be detected at 4$σ$. The results are analysed in combination with optical spectroscopy data from SDSS which we use to estimate the local galaxy density based on the Voronoi-Delaunay method. In total we detect 457 HI sources, 213 of which are detected for the first time by the AGES survey, 134 of which are presented in this article for the first time. 225 of the detections are in the cluster and 232 in the remaining volume surveyed. Here we present the full catalogue of HI detections and their basic properties, including optical ones. We concentrate on the difference between the cluster and the foreground and background LSS, revealing a continuous correlation of HI detected fraction (and HI deficiency) with local galaxy density, independent of global environment.
