A Wandering 35,000-Solar-Mass Black Hole Fed by a Gravitational Wake
Xin Li, Yong Shi, Fuyan Bian +8
Intermediate-mass black holes are widely considered to be the seeds of supermassive black holes, a substantial population of which is expected to remain displaced from galactic nuc…
A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Stellar metallicity gradients () provide a fossil record of the assembly history of galaxies. We present an analysis of for 90 nearby low-mass galaxies u…
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 negative stellar massgaseous metallicity gradient relation of dwarf galaxies modulated by stellar feedback
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Baryonic cycling is reflected in the spatial distribution of metallicity within galaxies, yet gas-phase metallicity distribution and its connection with other properties of dwarf g…
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…
The \ion{H}{I}-rich Ultra-diffuse Galaxies follow the Extended Schmidt Law
Sai Zhai, Yong Shi, Zhi-Yu Zhang +7
The \ion{H}{I}-rich ultra-diffuse galaxies (HUDGs) offer a unique case for studies of star formation laws (SFLs) as they host low star formation efficiency (SFE) and low-metallicit…
An Escaping Outflow in a Galaxy with an Intermediate-mass Black Hole
Zhiyuan Zheng, Yong Shi, Fuyan Bian +5
While in massive galaxies active galactic nuclei (AGN) feedback plays an important role, the role of AGN feedback is still under debate in dwarf galaxies. With well spatially resol…
The HI Gas Disk Thickness of the Ultra-diffuse Galaxy AGC 242019
Xin Li, Yong Shi, Zhi-Yu Zhang +5
Ultra-diffuse galaxies (UDGs) are as faint as dwarf galaxies but whose sizes are similar to those of spiral galaxies. A variety of formation mechanisms have been proposed, some of…
