HC3N Observations of Nearby Galaxies
Xue-Jian Jiang, Jun-Zhi Wang, Yu Gao +1
Aims. We aim to systematically study the properties of the different transitions of the dense molecular gas tracer HC3N in galaxies. Methods. We have conducted single-dish observat…
Carbon monoxide in an extremely metal-poor galaxy
Yong Shi, Junzhi Wang, Zhi-Yu Zhang +4
Extremely metal-poor galaxies with metallicity below 10% of the solar value in the local universe are the best analogues to investigating the interstellar medium at a quasi-primiti…
Millimeter Spectral Line Mapping Observations Toward Four Massive Star Forming HII Regions
Shanghuo Li, Junzhi Wang, Zhi-Yu Zhang +6
We present spectral line mapping observations toward four massive star-forming regions (Cepheus A, DR21S, S76E and G34.26+0.15), with the IRAM 30 meter telescope at 2 mm and 3 mm b…
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…
