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…
The relation between black hole spin, star formation rate, and black hole mass for supermassive black holes
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
Both theoretical models and observational evidence indicate that jets and/or outflows driven by central active supermassive black holes exert a significant feedback effect on the o…
The relation between black hole spin and star formation in massive star-forming galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
It has always been believed that feedback from active galactic nuclei (AGN) has an important impact on star formation in massive galaxies. Black hole spin is an important physical…
