TL;DR: In this paper, the authors collected optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for a total of 76 GRBs, and presented an additional three pre-Swift GRBs not included in an earlier sample.
Optical Spectral Variability of the Very-High-Energy Gamma-Ray Blazar 1ES 1011+496

Time-Dependent Synchrotron and Compton Spectra from Microquasar Jets
S. Gupta,Markus Böttcher +1 more
TL;DR: In this paper, the synchrotron and Compton signatures of time-dependent electron injection and acceleration, and adiabatic and radiative cooling in the jets of Galactic microquasars were studied.
A Time-dependent Leptonic Model for Microquasar Jets: Application to LS I +61 303
S. Gupta,Markus Böttcher +1 more
TL;DR: In this article, a time-dependent leptonic jet model was applied to the broadband spectral energy distribution (SED), and an orbital modulation of the very high energy (VHE) γ-ray emission of this source was suggested.

TL;DR: The first indications of a class of long GRBs are presented, which form a bridge between the typical high-luminosity, high-redshift events and nearby low- luminosity events (which are also associated with spectroscopic supernovae) in terms of energetics and observed redshift distribution, indicating a continuous distribution overall.
