SMT CO (2-1) Observations of Nearby Star-Forming Galaxies
Xue-Jian Jiang, Zhong Wang, Qiusheng Gu +2
We present CO =2-1 observations towards 32 nearby gas-rich star-forming galaxies selected from the ALFALFA and WISE catalogs, using the Sub-millimeter Telescope. Our sample is s…
Inefficient Star Formation In Extremely Metal Poor Galaxies
Yong Shi, Lee Armus, George Helou +5
The first galaxies contain stars born out of gas with little or no metals. The lack of metals is expected to inhibit efficient gas cooling and star formation but this effect has ye…
VLA observations of ammonia in high-mass star formation regions
Xing Lu, Qizhou Zhang, Hauyu Baobab Liu +2
We report systematic mapping observations of the NH (1,1) and (2,2) inversion lines towards 62 high-mass star-forming regions using VLA in its D and DnC array configurations.…
Dense Gas Tracers and Star Formation Laws in Active Galaxies: APEX Survey of HCN J=4-3, HCO+ J=4-3, and CS J=7-6
Zhi-Yu Zhang, Yu Gao, Christian Henkel +4
We report HCN J=4-3, HCO+ J=4-3, and CS J=7-6 observations in 20 nearby star-forming galaxies with the Acatama Pathfinder EXperiment 12-m telescope. Combined with 4 HCN, 3 HCO+, an…
