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 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…
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…
