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…
A strong He II 1640 emitter with extremely blue UV spectral slope at : presence of Pop III stars?
Xin Wang, Cheng Cheng, Junqiang Ge +12
Cosmic hydrogen reionization and cosmic production of first metals are major phase transitions of the universe occurring during the first billion years after the Big Bang, however…
Very Large Array Multi-band Radio Imaging of the Triple AGN Candidate SDSS J0849+1114
Sijia Peng, Zhiyuan Li, Xin Liu +3
Kpc-scale triple active galactic nuclei (AGNs), potential precursors of gravitationally-bound triple massive black holes (MBHs), are rarely seen objects and believed to play an imp…
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…
