Made-to-measure galaxy models - III Modelling with Milky Way observations
R. J. Long, Shude Mao, Juntai Shen +1
We demonstrate how the Syer & Tremaine made-to-measure method of stellar dynamical modelling can be adapted to model a rotating galactic bar. We validate our made-to-measure change…
Gas depletion in cluster galaxies depends strongly on their internal structure
Wei Zhang, Cheng Li, Guinevere Kauffmann +1
We analyze galaxies in 300 nearby groups and clusters identified in the Sloan Digital Sky Survey using a photometric gas mass indicator that is useful for estimating the degree to…
Classification Study of WISE Infrared Sources: Identification of Candidate Asymptotic Giant Branch Stars
Xun Tu, Zhongxiang Wang
In the WISE all-sky source catalogue there are 76 million mid-infrared (MIR) point sources that were detected at the first three WISE bands and have association with only one 2MASS…
LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) The survey science plan
Licai Deng, Heidi Jo Newberg, Chao Liu +22
We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly the Large Area Multi-Object…
The selection of LEGUE disk targets for LAMOST's pilot survey
Li Chen, Jinliang Hou, Jincheng Yu +18
We describe the target selection algorithm for the low latitude disk portion of the LAMOST Pilot Survey, which aims to test systems in preparation for the LAMOST spectroscopic surv…
The Vertical X-shaped Structure in the Milky Way: Evidence from a Simple Boxy Bulge Model
Zhao-Yu Li, Juntai Shen
A vertical X-shaped structure was recently reported in the Galactic bulge. Here we present evidence of a similar X-shaped structure in the Shen et al. (2010) bar/boxy bulge model t…
