The all-sky coverage of the Planck Early Release Compact Source Catalogue (ERCSC) provides an unsurpassed survey of galaxies at submillimetre (submm) wavelengths, representing a major improvement in the numbers of galaxies detected, as well as the range of far-IR/submm wavelengths over which they have been observed. We here present the first results on the properties of nearby galaxies using these data. We match the ERCSC catalogue to IRAS-detected galaxies in the Imperial IRAS Faint Source Redshift Catalogue (IIFSCz), so that we can measure the spectral energy distributions (SEDs) of these objects from 60 to 850 microns. This produces a list of 1717 galaxies with reliable associations between Planck and IRAS, from which we select a subset of 468 for SED studies, namely those with strong detections in the three highest frequency Planck bands and no evidence of cirrus contamination. The SEDs are fitted using parametric dust models to determine the range of dust temperatures and emissivities. We find evidence for colder dust than has previously been found in external galaxies, with T<20K. Such cold temperatures are found using both the standard single temperature dust model with variable emissivity beta, or a two dust temperature model with beta fixed at 2. We also compare our results to studies of distant submm galaxies (SMGs) which have been claimed to contain cooler dust than their local counterparts. We find that including our sample of 468 galaxies significantly reduces the distinction between the two populations. Fits to SEDs of selected objects using more sophisticated templates derived from radiative transfer models confirm the presence of the colder dust found through parameteric fitting. We thus conclude that cold (T<20K) dust is a significant and largely unexplored component of many nearby galaxies.

Constraints on Pre-Recombination Early Dark Energy from SPT-3G Public Data
早期的暗能量（EDE）是一种针对哈勃张力的解决方案，其中一个新的宇宙学场在复合之前加速宇宙膨胀，并减小声音视界的物理尺寸。在以前的工作中，在最新的阿塔卡玛宇宙望远镜数据（ACT DR 4）中发现了对非零EDE贡献的轻微偏好，而普朗克卫星遗留数据本身并没有显示出证据。我们发现，在目前的精度水平的SPT-3G，EDE的贡献，宇宙的总能量密度之前的重组$\sim 10\%$不能被排除，但数据也是一致的，没有EDE。ACT DR 4和SPT-3G与普朗克大尺度温度各向异性测量的组合显示了非零EDE的提示（$2.6σ$）;然而，当包括完整的普朗克2018数据集时，这种偏好消失了。
