VLT/MUSE Study of Close AGN Pairs and Host Galaxies in the Local Universe. I. Overview of the Ionized Gas
Xiaoyu Xu, Zhiyuan Li, Meicun Hou +3
Studying AGN pairs and their host galaxies is essential for understanding the interplay between galaxy mergers and key internal processes such as supermassive black hole fueling an…
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
Lin He, Zhiyuan Li, Zongnan Li +3
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…
AMUSE-Antlia. II. Intracluster X-ray Population in the Antlia Cluster
Zhensong Hu, Yuanyuan Su, Zhiyuan Li +4
We conduct a systematic survey of X-ray sources in the inner ( kpc) region of the Antlia cluster based on \Chandra observations, down to a source detection limit of $ L(0…
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…
