Metallicity distributions of mono-age stellar populations of the Galactic disc from the LAMOST Galactic spectroscopic surveys
C. Wang, X. -W. Liu, M. -S. Xiang +6
We have investigated the metallicity distributions of mono-age stellar populations across the disc of \,kpc and \,kpc using samples select…
Swift Monitoring Observations of Mrk 231: Detection of Ultraviolet Variability
Lilan Yang, Xinyu Dai, Youjun Lu +2
We analyze 168 Swift monitoring observations of the nearest broad absorption line quasar Mrk 231 in the UV and X-ray bands, where we detect significant variability in the UV ($\sim…
Investigation of the orientation of galaxies in clusters: the importance, methods and results of research
Paulina Pajowska, Wlodzimierz Godlowski, Zong-Hong Zhu +3
Various models of structure formation can account for various aspects of the galaxy formation process on different scales, as well as for various observational features of structur…
Inside a Beehive: the Multiple Merging Processes in the Galaxy Cluster Abell 2142
Ang Liu, Heng Yu, Antonaldo Diaferio +5
To investigate the dynamics of the galaxy cluster A2142, we compile an extended catalog of 2239 spectroscopic redshifts of sources, including newly measured 237 redshifts, within 3…
Stellar mass distribution and star formation history of the Galactic disk revealed by mono-age stellar populations from LAMOST
Maosheng Xiang, Jianrong Shi, Xiaowei Liu +8
We present a detailed determination and analysis of 3D stellar mass distribution of the Galactic disk for mono-age populations using a sample of 0.93 million main-sequence turn-off…
Multi-color optical monitoring of ten blazars from 2005 to 2011
Nankun Meng, Xiaoyuan Zhang, Jianghua Wu +2
We carried out multi-color optical monitoring of a sample of ten blazars from 2005 to 2011. The sample contains 3 LBLs, 2 IBLs, 4 HBLs, and 1 FSRQ. Our monitoring focused on the lo…
On the kinematic signature of the Galactic warp as revealed by the LAMOST-TGAS data
Yang Huang, R. Schönrich, Xiaowei Liu +6
Using a sample of about 123,000 stars with accurate 3D velocity measurements from the LAMOST-TGAS data, we confirm the kinematic signature of the Galactic warp found by Schönrich &…
The Evolution of Chemical Abundance in Quasar Broad Line Region
Fei Xu, Fuyan Bian, Yue Shen +3
We study the relation between the metallicity of quasar broad line region (BLR) and black hole (BH) mass () and quasar bolometric luminosit…
Three-dimensional interstellar dust reddening maps of the Galactic plane
B. -Q. Chen, Y. Huang, H. -B. Yuan +6
We present new three-dimensional (3D) interstellar dust reddening maps of the Galactic plane in three colours, E(G-Ks), E(Bp-Rp) and E(H-Ks). The maps have a spatial angular resolu…
Intra-day optical multi-band quasi-simultaneous observation of BL Lacertae object S5 0716+714 from 2013 to 2016
Xiaoyuan Zhang, Jianghua Wu, Nankun Meng
We perform quasi-simultaneous optical multi-band monitoring of BL Lac object S5 0716+714 on seven nights from 2013 to 2016. Intra-day variability (IDV) is found on all seven nights…
Blooming Trees: Substructures and Surrounding Groups of Galaxy Clusters
Heng Yu, Antonaldo Diaferio, Ana Laura Serra +1
We develop the Blooming Tree Algorithm, a new technique that uses spectroscopic redshift data alone to identify the substructures and the surrounding groups of galaxy clusters, alo…
Member stars of the GD1 tidal stream from the SDSS, LAMOST and Gaia surveys
Yang Huang, Xiaowei Liu, Bingqiu Chen +5
With the photometric data from the SDSS survey, the spectroscopic data from the SDSS/SEGUE and the LAMOST surveys, and the astrometric data from the Gaia DR2, we have identified 71…
