A FAST Survey of HINSA in PGCCs Guided by HC3N
Xunchuan Liu, Yuefang Wu, Chao Zhang +11
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we search for HI narrow-line self-absorption (HINSA) features in twelve Planck Galactic cold clumps (PGCCs),…
The cosmic environment overtakes the local density in shaping galaxy star formation
Jian Ren, Zhizheng Pan, XianZhong Zheng +11
The gas supply from the cosmic web is the key to sustain star formation in galaxies. It remains to be explored how the cosmic large-scale structure (LSS) effects on galaxy evolutio…
A census of optically dark massive galaxies in the early Universe from magnification by lensing galaxy clusters
Xinwen Shu, Lei Yang, Daizhong Liu +10
We present ALMA 870um and JCMT SCUBA2 850um dust continuum observations of a sample of optically dark and strongly lensed galaxies in the cluster fields. The ALMA and SCUBA2 observ…
Starduster: A multi-wavelength SED model based on radiative transfer simulations and deep learning
Yisheng Qiu, Xi Kang
We present Starduster, a supervised deep learning model that predicts the multi-wavelength SED from galaxy geometry parameters and star formation history by emulating dust radiativ…
An ALMA Spectroscopic Survey of the Brightest Submillimeter Galaxies in the SCUBA-2-COSMOS field (AS2COSPEC): Survey Description and First Results
Chian-Chou Chen, Cheng-Lin Liao, Ian Smail +11
We introduce an ALMA band 3 spectroscopic survey, targeting the brightest submillimeter galaxies (SMGs) in the COSMOS field. Here we present the first results based on the 18 prima…
The Complexity of the Cetus Stream Unveiled from the Fusion of STREAMFINDER and StarGO
Zhen Yuan, Khyati Malhan, Federico Sestito +16
We combine the power of two stream-searching tools, STREAMFINDER and StarGO applied to the Gaia EDR3 data, to detect stellar debris belonging to the Cetus stream system that forms…
