Spatial distribution of C4H and c-C3H2 in cold molecular cores
Yijia Liu, Junzhi Wang, Shu Liu +6
CH and -CH, as unsaturated hydrocarbon molecules, are important for forming large organic molecules in the interstellar medium. We present mapping observations of C$…
Deep HI Mapping of Stephan's Quintet and Its Neighborhood
Cheng Cheng, Cong Kevin Xu, P. N. Appleton +8
We carried out deep mapping observations of the atomic hydrogen (HI) 21 cm line emission in a field centered on the famous galaxy group Stephan's Quintet (SQ), using the Five-hundr…
The Distribution of UV Radiation Field in the Molecular Clouds of Gould Belt
Jifeng Xia, Ningyu Tang, Qijun Zhi +5
The distribution of ultraviolet (UV) radiation field provides critical constraints on the physical environments of molecular clouds. Within 1 kpc of our solar system and fostering…
A 0.6 Mpc HI Structure Associated with Stephan's Quintet
C. K. Xu, C. Cheng, P. N. Appleton +8
Stephan's Quintet (SQ, distance=856 Mpc) is unique among compact groups of galaxies. Observations have previously shown that interactions between multiple members, including a…
Mass flow in the circumbinary disk with gap around supermassive binary black holes
Ning-Yu Tang, Ye-Fei Yuan
In this paper, we study the interaction between the supermassive binary black holes in elliptical orbit and their surrounding disk with a gap. The gap in the disk is a low density…
