Why Are Some Optically Red Spirals NUV-r Blue?
Rui Guo, Cai-Na Hao, Xiaoyang Xia +2
To understand the complicated formation processes of disk galaxies, we carry out a comparative study for NUV-r blue and red spiral galaxies drawn from a parent sample of u-r red sp…
HI content of massive red spiral galaxies observed by FAST
Lan Wang, Zheng Zheng, Cai-Na Hao +9
A sample of 279 massive red spirals was selected optically by Guo et al. (2020), among which 166 galaxies have been observed by the ALFALFA survey. In this work, we observe HI cont…
The North/South Asymmetry of the Galaxy: Possible Connection to the Vertical Phase Space Snail
Rui Guo, Juntai Shen, Zhao-yu Li +2
The Galaxy is found to be in disequilibrium based on recent findings of the North/South (N/S) asymmetry and the phase mixing signatures, such as a phase spiral (snail) structure in…
Star formation histories of massive red spiral galaxies in the local universe
Shuang Zhou, Cheng Li, Cai-Na Hao +3
We investigate the star formation histories (SFHs) of massive red spiral galaxies with stellar mass , and make comparisons with blue spirals and red ellipt…
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…
Measuring the local dark matter density with LAMOST DR5 and Gaia DR2
Rui Guo, Chao Liu, Shude Mao +3
We apply the vertical Jeans equation to the kinematics of Milky Way stars in the solar neighbourhood to measure the local dark matter density. More than 90,000 G- and K-type dwarf…
A discrete chemo-dynamical model of M87's globular clusters: Kinematics extending to ~ 400 kpc
Chao Li, Ling Zhu, R. J. Long +14
We study the mass distribution and kinematics of the giant elliptical galaxy M87 (NGC 4486) using discrete chemo-dynamical, axisymmetric Jeans equation modelling. Our catalogue com…
Diagonal Ridge pattern of different age populations found in Gaia DR2 with LAMOST Main-Sequence-Turn-Off and OB type Stars
H. -F. Wang, Y. Huang, H. -W. Zhang +5
We revisit the diagonal ridge feature (diagonal distributions in the plane) found in and present timing analysis for it between Galactocentric distances of …
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…
SDSS-IV MaNGA: pattern speeds of barred galaxies
Rui Guo, Shude Mao, E. Athanassoula +5
The MaNGA project has obtained IFU data for several thousand nearby galaxies, including barred galaxies. With the two dimensional spectral and kinematic information provided by IFU…
Probing satellite galaxies in the Local Group by using FAST
Jing Li, Yougang Wang, Minzhi Kong +3
The abundance of neutral hydrogen (HI) in satellite galaxies in the Local Group is important for studying the formation history of our Local Group. In this work, we generated mock…
The Evolution of Advanced Merger (U)LIRGs on the Color-Stellar Mass Diagram
Rui Guo, Cai-Na Hao, Xiao-Yang Xia
Based on a sample of 79 local advanced merger (adv-merger) (U)LIRGs, we search for the evidence of quenching process by investigating the distributions of the star formation histor…
The role of major gas-rich mergers on the evolution of galaxies from the blue cloud to the red sequence
Rui Guo, Cai-Na Hao, X. Y. Xia +2
With the aim of exploring the fast evolutionary path from the blue cloud of star-forming galaxies to the red sequence of quiescent galaxies in the local universe, we select a local…
Observational evidence for the evolution of nuclear metallicity and star formation rate as the merger stage
Rui Guo, Cai-Na Hao, Xiao-Yang Xia +2
We investigate the evolution of nuclear gas-phase oxygen abundance and star formation rate (SFR) of local far-infrared selected star-forming galaxies along the merger sequence, as…
