Jets, accretion and spin in supermassive black holes

Yongyun Chen, Qiusheng Gu, Jianghe Yang +5

The theoretical model suggests that relativistic jets of AGN rely on the black hole spin and/or accretion. We study the relationship between jet, accretion, and spin using supermas…

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 jet formation mechanism of Gamma-ray Narrow-line Seyfert 1 Galaxies

Chen Yongyun, Gu Qiusheng, Fan Junhui +4

Under the coronal magnetic field, we estimate the maximal jet power of the Blandford-\Znajek (BZ) mechanism, Blandford-\Payne (BP) mechanism, and hybrid model. The jet power of the…

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…

Starbursts with suppressed velocity dispersion revealed in a forming cluster at z=2.51

Mengyuan Xiao, Tao Wang, David Elbaz +19

One of the most prominent features of galaxy clusters is the presence of a dominant population of massive ellipticals in their cores. Stellar archaeology suggests that these gigant…
