The afterglows of swift-era gamma-ray bursts. II. Type I GRB versus type II GRB optical afterglows

DA Kann, S Klose, B Zhang, S Covino… - The Astrophysical …, 2011 - iopscience.iop.org
Gamma-ray bursts (GRBs) have been separated into two classes, originally along the lines
of duration and spectral properties, called" short/hard" and" long/soft." The latter have been …

Constraining gamma-ray burst initial Lorentz factor with the afterglow onset feature and discovery of a tight Γ0–Eγ, iso correlation

EW Liang, SX Yi, J Zhang, HJ Lü… - The Astrophysical …, 2010 - iopscience.iop.org
The onset of gamma-ray burst (GRB) afterglow is characterized by a smooth bump in the
early afterglow light curve as the GRB fireball is decelerated by the circumburst medium. We …

[HTML][HTML] A comprehensive analysis of Swift XRT data. II. Diverse physical origins of the shallow decay segment

EW Liang, BB Zhang, B Zhang - The Astrophysical Journal, 2007 - iopscience.iop.org

How bad or good are the external forward shock afterglow models of gamma-ray bursts?

XG Wang, B Zhang, EW Liang, H Gao… - The Astrophysical …, 2015 - iopscience.iop.org
The external forward shock models have been the standard paradigm to interpret the
broadband afterglow data of gamma-ray bursts (GRBs). One prediction of the models is that …
