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…
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…
Discovery of giant bubbles in the hot gaseous halo of the massive disk galaxy NGC 6286

Based on archival Chandra X-ray observation, optical integral-field spectroscopic data and radio interferometric data, we report the discovery of a pair of giant bubbles (with a pr…
Probing the Hot Gaseous Halo of the Low-mass Disk Galaxy NGC 7793 with eROSITA and Chandra
Lin He, Zhiyuan Li, Meicun Hou +3
Galaxy formation models predict that local galaxies are surrounded by hot X-ray-emitting halos, which are technically difficult to detect due to their extended and low surface brig…
Uncovering an Excess of X-ray Point Sources in the Halos of Virgo Late-type Galaxies
Zhensong Hu, Meicun Hou, Zhiyuan Li

Four ultra-luminous infrared galaxies (ULIRGs) observed with JWST/NIRcam in the Cosmos Evolution Early Release Science program offer an unbiased preview of the ULIRG po…
A Chandra X-ray Survey of Optically Selected Close Galaxy Pairs: Unexpectedly Low Occupation of Active Galactic Nuclei
Lin He, Meicun Hou, Zhiyuan Li +2
High-resolution X-ray observations offer a unique tool for probing the still elusive connection between galaxy mergers and active galactic nuclei (AGNs). We present an analysis of…
NOEMA Detection of Circumnuclear Molecular Gas in X-ray Weak Dual Active Galactic Nuclei: No Evidence for Heavy Obscuration
Meicun Hou, Zhiyuan Li, Xin Liu +5
Dual active galactic nuclei (AGN), which are the manifestation of two actively accreting supermassive black holes (SMBHs) hosted by a pair of merging galaxies, are a unique laborat…
