我们提出了银河系冷团的普朗克目录（PGCC），一个全天空的银河系冷团候选者的普朗克探测目录。该目录是早期冷芯（ECC）目录的完整版本，该目录于2011年与早期发布紧凑源目录（ERCSC）一起提供，其中包含915个高信噪比源。它基于普朗克48个月的使命数据，目前正在向天文学界发布。PGCC星表是一个专门由银河系冷源组成的观测星表。三个最高的普朗克波段（857，454和353 GHz）与3 THz的IRAS数据相结合，对比当地环境更冷的源进行多频检测。在排除了可能的河外污染物之后，PGCC目录包含了遍布整个天空的13188个银河源，即，从银河平面到高纬度，遵循主要分子云复合体的空间分布。PGCC源的中位温度在13和14.5 K之间，这取决于X射线密度测量的质量，在去除具有前1%最高温度估计的源之后，温度范围从5.8到20 K。使用7个独立的方法，可靠的距离估计已经获得了5574个来源，这使我们能够推导出它们的物理性质，如它们的质量，物理尺寸，平均密度和光度。PGCC源主要位于太阳附近，但在银河系中心方向上的距离也高达10.5 kpc，范围从低质量核心到大分子云。由于这种多样性和PGCC目录包含非常不同环境中的源，该目录对于研究从分子云到核的演化是有用的。最后，它还包括位于小麦哲伦云和大麦哲伦云中的54个额外的源。
We present the Planck Catalogue of Galactic Cold Clumps (PGCC), an all-sky catalogue of Galactic cold clump candidates detected by Planck . This catalogue is the full version of the Early Cold Core (ECC) catalogue, which was made available in 2011 with the Early Release Compact Source Catalogue (ERCSC) and which contained 915 high signal-to-noise sources. It is based on the Planck 48-month mission data that are currently being released to the astronomical community. The PGCC catalogue is an observational catalogue consisting exclusively of Galactic cold sources. The three highest Planck bands (857, 454, and 353 GHz) have been combined with IRAS data at 3 THz to perform a multi-frequency detection of sources colder than their local environment. After rejection of possible extragalactic contaminants, the PGCC catalogue contains 13188 Galactic sources spread across the whole sky, i.e., from the Galactic plane to high latitudes, following the spatial distribution of the main molecular cloud complexes. The median temperature of PGCC sources lies between 13 and 14.5 K, depending on the quality of the flux density measurements, with a temperature ranging from 5.8 to 20 K after removing the sources with the top 1% highest temperature estimates. Using seven independent methods, reliable distance estimates have been obtained for 5574 sources, which allows us to derive their physical properties such as their mass, physical size, mean density, and luminosity. The PGCC sources are located mainly in the solar neighbourhood, but also up to a distance of 10.5 kpc in the direction of the Galactic centre, and range from low-mass cores to large molecular clouds. Because of this diversity and because the PGCC catalogue contains sources in very di ff erent environments, the catalogue is useful for investigating the evolution from molecular clouds to cores. Finally, it also includes 54 additional sources located in the Small and Large Magellanic Clouds.
