Three-dimensional structure of the milky way dust: modeling of LAMOST data
Linlin Li, Shiyin Shen, Jinliang Hou +5
We present a three-dimensional modeling of the Milky Way dust distribution by fitting the value-added star catalog of LAMOST spectral survey. The global dust distribution can be de…

The luminosity dependence of quasar UV continuum slope: dust extinction scenario
Xiaoyi Xie, Zhengyi Shao, Shiyin Shen +2
We investigate the UV continuum slope of a large quasar sample from SDSS DR7. By using specific continuum windows, we build two samples at lower () and higher ($1.…

Selecting M-giants with infra-red photometry: Distances, metallicities and the Sagittarius stream
Jing Li, Martin C. Smith, Jing Zhong +9
Using a spectroscopically confirmed sample of M-giants, M-dwarfs and quasars from the LAMOST survey, we assess how well WISE 2MASS color-cuts can be used to select M-giant sta…
