Wind-fed Supermassive Black Hole Accretion in the Ultracompact Dwarf Galaxy M60-UCD1
Zhao Su, Zhiyuan Li, Meicun Hou
Ultracompact dwarf galaxies (UCDs) are thought to be remnants of stripped galactic nuclei, among which a handful are known to host a central supermassive black hole (SMBH). As in s…
Hydrodynamic Evolution and Detectability of Nova Remnants in the Galactic Center
Zhao Su, Zhiyuan Li
Thousands of X-ray sources have been detected in the Galactic center (GC), most believed to be cataclysmic variables (CVs). As a potential probe of the old stellar population, in p…
Episodic Feedback in Triple AGN Candidate SDSS J0849+1114 Revealed by Extended ionized gas
Xiaoyu Xu, Meicun Hou, Zhiyuan Li +5
Galaxy mergers funnel gas toward the nuclei, igniting starbursts and active galactic nuclei (AGNs). The AGN feedback can reshape the host galaxy and regulate both star formation an…
Is the Peculiar Galactic Center Transient Swift J174610.4-290018 A Nova Outburst?
Ziqian Hua, Zhiyuan Li, Zhao Su
Swift J174610.4-290018 is a peculiar transient X-ray source in the Galactic center. First detected by Swift at the onset of an outburst in February 2024, it has since been observed…
Wind-fed Supermassive Black Hole Accretion by the Nuclear Star Cluster: the Case of M31*
Zhao Su, Zhiyuan Li, Zongnan Li
The central supermassive black hole (SMBH) of the Andromeda galaxy, known as M31*, exhibits dim electromagnetic emission and is inferred to have an extremely low accretion rate for…
Ring or no ring -- Revisiting the Multiphase Nuclear Environment in M31
Zongnan Li, Zhao Su, Sumin Wang +9
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 r…
Observational Evidence for Hot Wind Impact on pc-scale in Low-luminosity Active Galactic Nucleus
Fangzheng Shi, Feng Yuan, Zhiyuan Li +2
Supermassive black holes in galaxies spend majority of their lifetime in the low-luminosity regime, powered by hot accretion flow. Strong winds launched from the hot accretion flow…
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…
