Revealing the Physical Driver of the Baldwin Effect: Gas Density in the Broad-Line Region
Wen-Qiang Liang, Zhi-Fu Chen, Rui-Jing Lu +8
The Baldwin effect --- the inverse correlation between the equivalent width of emission lines and the continuum luminosity in active galactic nuclei (AGNs) --- has been known for n…
The infrared traced star formation rates of associated absorption lines quasars
Zhe-Geng Chen, Rui-Jing Lu, Zhi-Fu Chen +4
Some optically selected quasars exhibit Mg II assoicated absorption lines (AALs), and its origin remains unclear. In this paper, we compile a sample of 1769 quasars, with or withou…
Observational Evidence of Particles Acceleration by Relativistic Magnetic Reconnection in Gamma-ray Bursts
Cheng-Feng Peng, Rui-Jing Lu, Wen-Qiang Liang +1
Gamma-ray bursts (GRBs) as the most energetic explosions in the modern universe have been studied over half a century, but the physics of the particle acceleration and radiation re…
Reconstruction of luminosity function from flux-limited samples
Rui-Jing Lu, Wen-Hao Chen, Wen-Qiang Liang +1
The properties of the progenitors of gamma-ray bursts (GRBs) and of their environment are encoded in their luminosity function and cosmic formation rate. They are usually recovered…
