The Compactness of Galaxy Groups in the Sloan Digital Sky Survey
Yunliang Zheng, Shiyin Shen, Shuai Feng
We use an updated version of the halo-based galaxy group catalog of Yang et al., and take the surface brightness of the galaxy group () based on projected positions an…
A catalogue of 323 cataclysmic variables from LAMOST DR6
Yongkang Sun, Zhenghao Cheng, Shuo Ye +17
In this work, we present a catalog of cataclysmic variables (CVs) identified from the Sixth Data Release (DR6) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAM…
CAHA/PPAK Integral-field Spectroscopic Observations of M81 -- I. Circumnuclear ionized gas
Zongnan Li, Zhiyuan Li, Ruben Garcia-Benito +1
Galactic circumnuclear environments of nearby galaxies provide unique opportunities for our understanding of the co-evolution between super-massive black holes and their host galax…
An IFU View of the Active Galactic Nuclei in MaNGA Galaxy Pairs
Gaoxiang Jin, Y. Sophia Dai, Hsi-An Pan +10
The role of active galactic nuclei (AGNs) during galaxy interactions and how they influence the star formation in the system are still under debate. We use a sample of 1156 galaxie…
SDSS-IV MaNGA: Enhanced Star Formation in Galactic-scale Outflows
Min Bao, Yanmei Chen, Qirong Yuan +8
Using the integral field unit (IFU) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we collect a sample of 36 star forming galaxies that host galactic…
SDSS-IV MaNGA: The Radial Profile of Enhanced Star Formation in Close Galaxy Pairs
Joshua L. Steffen, Hai Fu, J. M. Comerford +4
We compare the radial profiles of the specific star formation rate (sSFR) in a sample of 169 star-forming galaxies in close pairs with those of mass-matched control galaxies in the…
The Flare and Warp of the Young Stellar Disk traced with LAMOST DR5 OB-type stars
Yang Yu, Hai-Feng Wang, Wen-Yuan Cui +9
We present analysis of the spatial density structure for the outer disk from 814 \,kpc with the LAMOST DR5 13534 OB-type stars and observe similar flaring on north and south sid…
