JINGLE是JCMT的一项新的遗产调查，旨在系统地研究局部宇宙中星系的冷星际介质。作为调查的一部分，我们用Scuba-2对193个赫歇尔精选星系的具有代表性的样本进行了850微米连续谱测量，其中90个星系的子集是M*>；109M⊙，以及与RxA3m积分的CO(2-1)线通量。样本是从Herschel-ATLAS调查覆盖的领域中挑选出来的，这些领域也是漫画光学积分场光谱调查的目标。新的JCMT观测结合多波长辅助数据，将允许对附近宇宙中尘埃的性质进行强有力的表征，并对尘埃、气体和全球星系性质之间的标度关系进行基准测试。本文概述了调查目标和有关样本选择和JCMT观测的细节，给出了一个一致的30波段UV-FIR光度星表，并介绍了JINGLE主要数据发布。科学上的亮点包括850微米光度和CO谱线光度之间的非线性关系(logLCO(2-1)= 1.372 logL850-1.376)，以及偶然发现的候选星系。
JINGLE is a new JCMT legacy survey designed to systematically study the cold interstellar medium of galaxies in the local Universe. As part of the survey we perform 850 µm continuum measurements with SCUBA-2 for a representative sample of 193Herschel-selected galaxies withM*> 109M⊙, as well as integrated CO(2–1) line fluxes with RxA3m for a subset of 90 of these galaxies. The sample is selected from fields covered by theHerschel-ATLAS survey that are also targeted by the MaNGA optical integral-field spectroscopic survey. The new JCMT observations combined with the multiwavelength ancillary data will allow for the robust characterization of the properties of dust in the nearby Universe, and the benchmarking of scaling relations between dust, gas, and global galaxy properties. In this paper we give an overview of the survey objectives and details about the sample selection and JCMT observations, present a consistent 30-band UV-to-FIR photometric catalogue with derived properties, and introduce the JINGLE Main Data Release. Science highlights include the non-linearity of the relation between 850 µm luminosity and CO line luminosity (logLCO(2–1)= 1.372 logL850–1.376), and the serendipitous discovery of candidatez> 6 galaxies.
