New Constraint of the Hubble Constant by Proper Motions of Radio Components Observed in AGN Twin-jets
Wei-Jian Lu, Yi-Ping Qin
As the advent of precision cosmology, the Hubble constant () inferred from the Lambda Cold Dark Matter fit to the Cosmic Microwave Background data is increasingly in tension w…
Velocity shift of Mg II and Al III broad absorption lines in quasar SDSS J134444.33+315007.6
Wei-Jian Lu, Ying-Ru Lin
We report, for the first time, a synchronized velocity shift of Mg II and Al III broad absorption lines (BALs) in quasar SDSS J134444.33+315007.6 (hereafter J1344+3150). We found t…
A Kinematic Shift of the C IV Broad Absorption Line in Quasar SDSS J120819.29+035559.4
Wei-Jian Lu, Ying-Ru Lin
We report the kinematic shift of the C IV broad absorption line (BAL) in quasar SDSS J120819.29+035559.4 (hereafter J1208+0355). This quasar shows two BAL systems, including a blue…
Correlations between the Variation of the Ionizing Continuum and Broad Absorption Lines in Individual Quasars
Wei-Jian Lu, Ying-Ru Lin
We discover the significant (significance level of >99%) correlations between the fractional variation of the ionizing continuum and that of the C IV and/or Si IV BALs in each of 2…
Narrow Absorption Lines Complex. III. Gradual Transition from Type S to Type N Broad Absorption Line
Wei-Jian Lu, Ying-Ru Lin
We study the relationship between the broad absorption lines (BALs) that can be decomposed into multiple narrow absorption lines and those that cannot (hereafter Type N and Type S…
Correlation between the ionizing continuum and variable C iv broad absorption line in multi-epoch observations of SDSS J141007.74+541203.3
Hong-Yan Huang, Cai-Juan Pan, Wei-Jian Lu +9
Correlation between the variations of quasar absorption lines and the ionizing continuum have been recently confirmed in systematic studies. However, no convincing individual case…
