摘要:

本文介绍了欧空局普朗克飞行任务在30和857 GHz之间观测到的普朗克非热(即同步加速器主导)源(PCNT)多频目录。这一目录是通过选择在30和143千兆赫的完整飞行任务全天空温度图中探测到的物体而编制的,在用特定的墨西哥帽小波滤波后,两个通道中至少有一个通道的信噪比(S/N)>3。结果,29400个源候选人被选中。然后,在这些物体的位置上使用矩阵滤波器方法进行多频率分析,并在9个普朗克通道中计算所有物体的通量密度和误差。目前的目录是第一份以毫米和亚毫米波长出版的同步辐射源的无偏差全天目录,是对河外非热辐射源进行统计研究的强大数据库,这些源的辐射主要由中央活动星系核控制。与完整的多频目录一起,我们还定义了非热源的Bright Planck多频目录PCNTb,其中仅选择了在30和143 GHz处S/N>4的对象。在这个星表中,1146个致密源在普朗克GAL 070掩模之外被探测到,因此,这些源构成了河外射电源的高度可靠的样本。我们还标记了高显著性子样本PCNTh,这是在所有9个普朗克通道中以S/N>4检测到的151个源的子集,其中75个在这里采用的普朗克掩模之外。银河系面具内的其余76个源极有可能是银河系天体。

英文摘要:

This paper presents the Planck Multi-frequency Catalogue of Non-thermal (i.e. synchrotron-dominated) Sources (PCNT) observed between 30 and 857 GHz by the ESA Planck mission. This catalogue was constructed by selecting objects detected in the full mission all-sky temperature maps at 30 and 143 GHz, with a signal-to-noise ratio (S/N)>3 in at least one of the two channels after filtering with a particular Mexican hat wavelet. As a result, 29400 source candidates were selected. Then, a multi-frequency analysis was performed using the Matrix Filters methodology at the position of these objects, and flux densities and errors were calculated for all of them in the nine Planck channels. The present catalogue is the first unbiased, full-sky catalogue of synchrotron-dominated sources published at millimetre and submillimetre wavelengths and constitutes a powerful database for statistical studies of non-thermal extragalactic sources, whose emission is dominated by the central active galactic nucleus. Together with the full multi-frequency catalogue, we also define the Bright Planck Multi-frequency Catalogue of Non-thermal Sources PCNTb, where only those objects with a S/N>4 at both 30 and 143 GHz were selected. In this catalogue 1146 compact sources are detected outside the adopted Planck GAL070 mask; thus, these sources constitute a highly reliable sample of extragalactic radio sources. We also flag the high-significance subsample PCNThs, a subset of 151 sources that are detected with S/N>4 in all nine Planck channels, 75 of which are found outside the Planck mask adopted here. The remaining 76 sources inside the Galactic mask are very likely Galactic objects.
