Supernova origin of galactic turbulence revealed by superbubbles
Fanyi Meng, Chao-Wei Tsai, Jingwen Wu +13
Supernovae (SNe) are among the leading candidates for powering galactic-scale turbulence. SNe drive expanding shells of neutral atomic hydrogen (HI) known as superbubbles. Due to t…
Ruling out conventional photoionization models in the closest LINER M31 with CFHT/SITELLE observations
Zongnan Li, Zhiyuan Li, Sumin Wang +2
The ionization mechanisms of low-ionization nuclear emission-line regions (LINERs), which are common in the local Universe, have been debated for decades. Our nearest large neighbo…
Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds
Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23
We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a 5…
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…
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…
The HASHTAG project II. Giant molecular cloud properties across the M31 disc
Yikai Deng, Zongnan Li, Zhiyuan Li +17
We present a study of giant molecular cloud (GMC) properties in the Andromeda galaxy (M31) using CO(3-2) data from the James Clerk Maxwell Telescope (JCMT) in selected regions acro…
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…
The ALMaQUEST Survey XV: The Dependence of the Molecular-to-Atomic Gas Ratios on Resolved Optical Diagnostics
Niankun Yu, Zheng Zheng, Chao-Wei Tsai +14
The atomic-to-molecular gas conversion is a critical step in the baryon cycle of galaxies, which sets the initial conditions for subsequent star formation and influences the multi-…
CAHA/PPAK Integral-field Spectroscopic Observations of M81. II. Testing Photoionization Models in A Spatially-resolved LINER
Zongnan Li, Zhiyuan Li, Ruben Garcia-Benito +1
The origin of the low-ionization nuclear emission-line region (LINER) prevalent in local galaxies and its relationship with supermassive black holes are debated for decades. We pre…
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…
CAHA/PPAK Integral-field Spectroscopic Observations of M81 -- I. Circumnuclear ionized gas
Zongnan Li, Zhiyuan Li, Ruben Garcia-Benito +1
Galactic circumnuclear environments of nearby galaxies provide unique opportunities for our understanding of the co-evolution between super-massive black holes and their host galax…
