Searching for the Transit of the Earth--mass exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result
Hui-Gen Liu, Peng Jiang, Xingxing Huang +21
Proxima Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth-mass planet around it. With an orbital period…
Quasar 2175 Å dust absorbers II: Correlation analysis and relationship with other absorption line systems
Jingzhe Ma, Jian Ge, J. Xavier Prochaska +6
We present the cold neutral content (H I and C I gas) of 13 quasar 2175 Å dust absorbers (2DAs) at = 1.6 - 2.5 to investigate the correlation between the presence of the UV…
Quasar 2175 Å dust absorbers I: metallicity, depletion pattern, and kinematics
Jingzhe Ma, Jian Ge, Yinan Zhao +4
We present 13 new 2175 Å dust absorbers at z_abs = 1.0 - 2.2 towards background quasars from the Sloan Digital Sky Survey. These absorbers are examined in detail using data from th…
Reddening and He I* Absorption Lines in Three Narrow-line Seyfert 1 Galaxies
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +6
We report the detection of heavy reddening and the He I* absorption lines at the AGNs' redshift in three Narrow-line Seyfert 1 galaxies: SDSS J091848.61+211717.0, SD…
