Identifying Compton-thick active galactic nuclei in the COSMOS. II. Searching among mid-infrared selected AGNs
Xiaotong Guo, Qiusheng Gu, Guanwen Fang +7
Compton-thick active galactic nuclei (CT-AGNs), defined by column density , are so heavily absorbed that their X-ray e…
The Starburst Acceleration of High-Velocity Clouds in the Galactic Center
Mengfei Zhang, Miao Li, Peixin Zhu
High-velocity clouds (HVCs) in the Galactic center have garnered significant attention due to their mysterious formation, potentially linked to starburst events or supermassive bla…
Not gone with the Wind: Survival of High-Velocity Molecular Clouds in the Galactic center
Mengfei Zhang, Miao Li
High-velocity atomic clouds in the Galactic center have attracted significant attention due to their enigmatic formation process, which is potentially linked to the starburst or su…
Hydrodynamic Evolution of Sgr A East: The Imprint of A Supernova Remnant in the Galactic Center
Mengfei Zhang, Zhiyuan Li, Ziqian Hua Mark R. Morris
We perform three-dimensional numerical simulations to study the hydrodynamic evolution of Sgr A East, the only known supernova remnant (SNR) in the center of our Galaxy, to infer i…
Chandra X-ray Measurement of Gas-phase Heavy Element Abundances in the Central Parsec of the Galaxy
Ziqian Hua, Zhiyuan Li, Mengfei Zhang +2
Elemental abundances are key to our understanding of star formation and evolution in the Galactic center. Previous work on this topic has been based on infrared (IR) observations,…
Magneto hydrodynamic simulations of the supernova remnant G1.9+0.3
Shaobo Zhang, Wenwu Tian, Mengfei Zhang +2
The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the n…
A Chandra Survey of Milky Way Globular Clusters. III. Searching for X-ray Signature of Intermediate-mass Black Holes
Zhao Su, Zhiyuan Li, Meicun Hou +2
Globular clusters (GCs) are thought to harbor the long-sought population of intermediate-mass black holes (IMBHs). We present a systematic search for a putative IMBH in 81 Milky Wa…
A Supernova-driven, Magnetically-collimated Outflow as the Origin of the Galactic Center Radio Bubbles
Mengfei Zhang, Zhiyuan Li, Mark R. Morris
A pair of non-thermal radio bubbles recently discovered in the inner few hundred parsecs of the Galactic center bears a close spatial association with elongated, thermal X-ray feat…
Extended radio AGN at z ~ 1 in the ORELSE survey: The confining effect of dense environments
Lu Shen, Guilin Liu, Mengfei Zhang +16
Recent hydrodynamic simulations and observations of radio jets have shown that the surrounding environment has a large effect on their resulting morphology. To investigate this we…
Galactic Center IRS13E: Colliding Stellar Winds or an Intermediate Mass Black Hole?
Zhenlin Zhu, Zhiyuan Li, Anna Ciurlo +4
A small cluster of massive stars residing in the Galactic center, collectively known as IRS13E, is of special interest due to its close proximity to Sgr A* and the possibility that…
The Distance Measurements of Supernova Remnants in The Fourth Galactic Quadrant
Su-Su Shan, Hui Zhu, Wen-Wu Tian +3
We take advantage of the red clump stars to build the relation of the optical extinction (AV) and distance in each direction of supernova remnants (SNRs) with known extinction in t…
How does the stellar wind influence the radio morphology of a supernova remnant?
M. F. Zhang, W. W. Tian, D. Wu
We simulate the evolutions of the stellar wind and the supernova remnant (SNR) originating from a runaway massive star in an uniform Galactic environment based on the three-dimensi…
The gas-to-extinction ratio and the gas distribution in the Galaxy
Hui Zhu, Wenwu Tian, Aigen Li +1
We investigate the relation between the optical extinction () and the hydrogen column density () determined from X-ray observations of a large sample of Galactic sightlin…
The revised distance of supernova remnant G15.4+0.1
H. Su, M. F. Zhang, H. Zhu +1
We measure the distance to the supernova remnant G15.4+0.1 which is likely associated with TeV source HESS J1818-154. We build the neutral hydrogen (HI) absorption and 13CO spectra…
