TL;DR: In this paper, the early afterglow emission from GRBs expanding into a pulsar wind bubble environment was studied and it was shown that GeV photons suffer negligible absorption by the soft photons radiation field in PWBs.

TL;DR: In this paper, the authors compared the broadband spectral properties of active galactic nuclei (AGNs) and gamma-ray bursts (GRBs) with the well-observed blazars.

TL;DR: The most luminous known supernova (SN) associated with a gamma-ray burst (GRB), SN 2011kl, was studied in this paper, where three groups derived three different bolometric light-curve (LC) evolution (broken or unbroken power-law function) of the optical afterglow of GRB 111209A.

TL;DR: In this article, a general method for testing gamma-ray burst (GRB) jet structure and carry out a comprehensive analysis of the prevalent jet structure models is presented, which can not only derive the expected distribution of the GRB isotropic-equivalent energy release for any possible jet structure, but also obtain a two-dimensional distribution including redshift z.

TL;DR: In this paper, the authors mainly focus on the possible maximum spin period of isolated NSs / magnetars dominated by an interaction between star's magnetic field and the disk, and find that the disk wind plays an important role in spin evolution, whose influence varies the power law index of mass flow rate.
