Post-starburst Galaxies with Active Galactic Nucleus: Properties and Evolutionary Sequences
Junjie Huang, Yanmei Chen, Yong Shi +7
Post-starburst (PSB) galaxies, identified by strong Balmer absorption and weak nebular emission, provide a key laboratory for studying rapid quenching. Using the final data release…
Properties of Galaxies with Counter-rotating Stellar Disks in the MaNGA Survey
Min Bao, Zhenyu Tang, Yanmei Chen +2
Gas accretion process can fuel both star formation and black hole activity, playing a critical role in galaxy evolution. The counter-rotating structures are believed to originate f…
Clumpy Starburst in a Local Dwarf Galaxy, NGC 1522
Liuze Long, Yulong Gao, Qiusheng Gu +8
To investigate the star-forming process in nearby dwarf galaxies, we present Integral Field Units (IFU) observation of the star-forming dwarf galaxy, NGC 1522, with the Very Large…
A Dual Active Black Hole Candidate with Mass Ratio ~7:1 in a Disk Galaxy
Xiao Cao, Yan-Mei Chen, Yong Shi +8
Dual active galactic nuclei (AGNs) with comparable masses are commonly witnessed among the major merged galaxies with interaction remnants. Considering almost every massive galaxy…
PGC 44685: A Dwarf Star-forming Lenticular Galaxy with Wolf-Rayet Population
Shiying Lu, Qiusheng Gu, Yulong Gao +8
Lenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still untangled. Based on spatially resolv…
Quasars with Flare/Eclipse-like Variability Identified in ZTF
Zhiyuan Zheng, Yong Shi, Shuowen Jin +4
Active galactic nuclei (AGNs) are known to exhibit optical/UV variability and most of them can be well modeled by the damped random walks. Physical processes that are not related t…
