TL;DR
This paper presents the first all-sky catalogue of cold galactic objects detected by Planck, analyzing their properties, distribution, and potential role as pre-stellar clumps, providing new insights into cold core populations.
Contribution
It introduces the Cold Core Catalogue of Planck Objects (C3PO), the first unbiased all-sky survey of cold galactic sources with detailed statistical analysis.
Findings
Most cold cores are within 2 kpc of the Sun.
Temperatures range from 7K to 17K, peaking around 13K.
Cold cores are organized in filaments associated with molecular clouds.
Abstract
We present the statistical properties of the first version of the Cold Core Catalogue of Planck Objects (C3PO), in terms of their spatial distribution, temperature, distance, mass, and morphology. We also describe the statistics of the Early Cold Core Catalogue (ECC, delivered with the Early Release Compact Source Catalogue, ERCSC) that is the subset of the 915 most reliable detections of the complete catalogue. We have used the CoCoCoDeT algorithm to extract 10783 cold sources. Temperature and dust emission spectral index {\beta} values are derived using the fluxes in the IRAS 100 \mum band and the three highest frequency Planck bands. Temperature spans from 7K to 17K, and peaks around 13K. Data are not consistent with a constant value of {\beta} over the all temperature range. {\beta} ranges from 1.4 to 2.8 with a mean value around 2.1, and several possible scenarios are possible,…
