Catalog of narrow absorption lines in BOSS (I): for quasars with
Zhi-Fu Chen, Yi-Ping Qin, Cai-Juan Pan +3
We have assembled absorption systems by visually identifying absorption doublets in the quasar spectra of the Baryon Oscillation Spectroscopic Survey (BOSS)…
Roles of the kinetic and dynamic mechanisms in the relation
Yi-Ping Qin, Zhi-Fu Chen
The relation is a well-known relation in gamma-ray bursts. Its implication remains unclear. We propose to investigate the underlying mechanisms of this relation by cons…
Statistical classification of gamma-ray bursts based on the Amati relation
Yi-Ping Qin, Zhi-Fu Chen
Gamma-ray bursts (GRBs) are believed to belong to two classes and they are conventionally divided according to their durations. This classification scheme is not satisfied due to t…
The disappearance of a narrow Mg II absorption system in quasar SDSS J165501.31+260517.4
Zhi-Fu Chen, Yi-Ping Qin, Min-Feng Gu
In this letter, we present for the first time, the discovery of the disappearance of a narrow Mg II absorption system from the spectra of quasar SDSS J165501.31…
Disappearance of a narrow Mg II absorption system with a measured velocity up to
Zhi-Fu Chen, Yi-Ping Qin
Quasar J152645.61+193006.7 () was observed by the Sloan Digital Sky Survey (SDSS) on 2006 May 31, and again on 2011 April 9. The time interval of the SDSS two obs…
Emergences of C IV narrow absorption troughs in the quasar SDSS J095254.10+021932.8
Zhi-Fu Chen, Mu-Sheng Li, Wei-Rong Huang +2
In this paper, we report on two C IV narrow absorption systems emerging from the spectrum of the quasar SDSS J095254.10 +021932.8, which are located at and $z_…
