Dwarf Galaxy Integral-field Survey (DGIS): survey overview and the result of global mass-metallicity relation
Xin Li, Yong Shi, Fuyan Bian +11
Low-mass galaxies are the building blocks of massive galaxies in the framework of hierarchical structure formation. To enable detailed studies of galactic ecosystems in dwarf galax…
Properties of a Fading AGN from SDSS-IV MaNGA
Hao Mo, Yan-Mei Chen, Zhi-Yun Zhang +7
We identify a fading AGN SDSS J220141.64+115124.3 from the internal Product Launch-11 (MPL-11) in Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey. The central re…
Multiple gas acquisition events in galaxies with dual misaligned gas disks
Xiao Cao, Yan-Mei Chen, Yong Shi +8
Frequent accretion of external cold gas is thought to play an important role in galaxy assembly. However, almost all known kinematically misaligned galaxies identify only one gas d…
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…
The major mechanism to drive turbulence in star-forming galaxies
Xiaoling Yu, Fuyan Bian, Mark R. Krumholz +3
Two competing models, gravitational instability-driven transport and stellar feedback, have been proposed to interpret the high velocity dispersions observed in high-redshift galax…
Probing possible effects of circumgalactic media on the metal content of galaxies through the mass-metallicity relationship
Sai Zhai, Yong Shi, Jianhang Chen +4
The circumgalactic medium (CGM) connects the gas between the interstellar medium (ISM) and the intergalactic medium, which plays an important role in galaxy evolution. We use the s…
A cuspy dark matter halo
Yong Shi, Zhi-Yu Zhang, Junzhi Wang +4
The cusp-core problem is one of the main challenges of the cold dark matter paradigm on small scales: the density of a dark matter halo is predicted to rise rapidly toward the cent…
Host Galaxy Properties of Changing-look AGN Revealed in the MaNGA Survey
Xiaoling Yu, Yong Shi, Yanmei Chen +6
Changing-look Active Galactic Nuclei (CL-AGNs) are a subset of AGNs in which the broad Balmer emission lines appear or disappear within a few years. We use the Mapping Nearby Galax…
Towards an Understanding of the Massive Red Spiral Galaxy Formation
Rui Guo, Cai-Na Hao, Xiaoyang Xia +4
To understand the formation and quenching processes of local massive red spiral galaxies with , we perform a statistical analysis of their spectrosco…
The Impact of Merging on The Origin of Kinematically Misaligned and Counter-rotating Galaxies in MaNGA
Song-lin Li, Yong Shi, Dmitry Bizyaev +7
Galaxy mergers and interactions are expected to play a significant role leading to offsets between gas and stellar motions in galaxies. Herein we crossmatch galaxies in MaNGA MPL-8…
The spatial extension of extended narrow line regions in MaNGA AGN
Jianhang Chen, Yong Shi, Ross Dempsey +10
In this work, we revisit the size-luminosity relation of the extended narrow line regions (ENLRs) using a large sample of nearby active galactic nuclei (AGN) from the Mapping Nearb…
Spatially Resolved Studies of Local Massive Red Spiral Galaxies
Cai-Na Hao, Yong Shi, Yanmei Chen +5
We report two-dimensional spectroscopic analysis of massive red spiral galaxies ( 10 ) and compare them to blue spiral and red elliptical galaxies ab…
What drives the velocity dispersion of ionized gas in star-forming galaxies?
Xiaoling Yu, Yong Shi, Yanmei Chen +11
We analyze the intrinsic velocity dispersion properties of 648 star-forming galaxies observed by the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, to explore…
An early-type galaxy with an inner star-forming disk
Song-lin Li, Yong shi, Yan-mei Chen +5
Early-type galaxies (ETGs) are composed of two distinct populations: high-mass and low-mass, which are likely to be built via gas-poor merging and gas-rich merging/accretion, respe…
