DEEM, a versatile platform of FRD measurement for highly multiplexed fibre systems in astronomy
Yunxiang Yan, Qi Yan, Gang Wang +6
We present a new method of DEEM, the direct energy encircling method, for characterising the performance of fibres in most astronomical spectroscopic applications. It's a versatile…
A modified method for determining the FRD and length properties of optical fibres in astronomy
Yunxiang Yan, Gang Wang, Weimin Sun +4
Focal ratio degradation (FRD) is a major contributor to throughput and light loss in a fibre spectroscopic telescope system. We combine the guided mode theory in geometric optics a…
Spectroscopically Identified Cataclysmic Variables from LAMOST survey. I. The Sample
Wen Hou, A-Li Luo, Yin-Bi Li +1
A sample of Cataclysmic Variables (CVs) is presented including spectroscopically identified 380 spectra of 245 objects, of which 58 CV candidates are new discoveries. The BaggingTo…
Bivariate Luminosity Function of Galaxy Pairs
Shuai Feng, Shi-Yin Shen, Fang-Ting Yuan +8
We measure the bivariate luminosity function (BLF) of galaxy pairs and use it to probe and characterize the galaxy-galaxy interaction between pair members. The galaxy pair sample i…
Stellar population analysis on the stacked spectra of double-peaked emission-line galaxies
Meng-Xin Wang, A-Li Luo
The double-peaked emission-line galaxies has long been perceived as objects related with merging galaxies or other phenomena of disturbed dynamical activities, such as outflows and…
Metallic-Line Stars Identified from Low Resolution Spectra of LAMOST DR5
Li Qin, A-Li Luo, Wen Hou +6
LAMOST DR5 released more than 200,000 low resolution spectra of early-type stars with S/N>50. Searching for metallic-line (Am) stars in such a large database and study of their sta…
