The MALATANG survey: star formation, dense gas, and AGN feedback in NGC 1068
Shuting Lin, Siyi Feng, Zhi-Yu Zhang +14
We aim to investigate the interplay between dense molecular gas, star formation, and active galactic nucleus (AGN) feedback in the luminous infrared galaxy (LIRG) NGC 1068 at sub-k…
The MALATANG survey: Dense gas distribution on sub-kiloparsec scales across the disk of M82
Jian-Fa Wang, Yu Gao, Qing-Hua Tan +23
We present observations of HCN J=4-3 and HCO^+ J=4-3 lines obtained with the James Clerk Maxwell Telescope as part of the MALATANG survey, combined with archival HCN J=1-0 and HCO^…
Cloud-cloud collision in S235: triggered the formation of high-mass stars and young star clusters
En Chen, Yu Gao, Shiyu Zhang +7
We present the analysis of cloud-cloud collision (CCC) process in the Galactic molecular complex S235. Our new CO observations performed with the PMO-13.7m telescope reveal two mol…
CO-CHANGES I: IRAM 30m CO Observations of Molecular Gas in the Sombrero Galaxy
Yan Jiang, Jiang-Tao Li, Yu Gao +7
Molecular gas plays a critical role in explaining the quiescence of star formation (SF) in massive isolated spiral galaxies, which could be a result of either the low molecular gas…
VALES VII: Molecular and ionized gas properties in pressure balanced interstellar medium of starburst galaxies at z ~ 0.15
Juan Molina, Edo Ibar, Nicolas Godoy +9
Context. Spatially resolved observations of the ionized and molecular gas are critical for understanding the physical processes that govern the interstellar medium (ISM) in galaxie…
The MALATANG Survey: Dense Gas and Star Formation from High Transition HCN and HCO+ maps of NGC253
Xue-Jian Jiang, Thomas R. Greve, Yu Gao +26
To study the high-transition dense-gas tracers and their relationships to the star formation of the inner 2 kpc circumnuclear region of NGC253, we present HCN and HC…
The HASHTAG project I. A Survey of CO(3-2) Emission from the Star Forming Disc of M31
Zongnan Li, Zhiyuan Li, Matthew W. L. Smith +26
We present a CO(3-2) survey of selected regions in the M31 disc as part of the JCMT large programme, HARP and SCUBA-2 High-Resolution Terahertz Andromeda Galaxy Survey (HASHTAG). T…
Estimating the molecular gas mass of low-redshift galaxies from a combination of mid-infrared luminosity and optical properties
Yang Gao, Ting Xiao, Cheng Li +17
We present CO(J=1-0) and/or CO(J=2-1) spectroscopy for 31 galaxies selected from the ongoing MaNGA survey, obtained with multiple telescopes. This sample is combined with CO observ…
Resolved neutral carbon emission in nearby galaxies: [CI] Lines as Total Molecular Gas Tracers
Qian Jiao, Yinghe Zhao, Nanyao Lu +6
We present maps of atomic carbon [CI](1-0) and [CI](2-1) at a linear resolution ~1kpc scale for a sample of one HII, six LINER, three Seyfert and five starburst galaxies observed w…
