TL;DR: In this paper, a large suite of multi-wavelength observations spanning from 300 s to 130 days after a gamma-ray burst (GRB 130427A) was presented, showing that the afterglow shows relatively simple, smooth evolution at all frequencies.

TL;DR: In this paper, the authors used radio astrometry to refine the distance to the black hole X-ray binary Cygnus X-1, which was found to be 2.22 − 0.17 + 0.18 kiloparsecs.
Journal ArticleDOI
Tests for Standard Accretion Disk Models by Variability in Active Galactic Nuclei
TL;DR: In this paper, the standard accretion disk models of active galactic nuclei (AGNs) are tested using light curves of 26 objects that have been well observed using reverberation mapping.
Journal ArticleDOI
The $E_{p}$ Evolutionary Slope within the Decay Phase of "FRED" Gamma-ray Burst Pulses
TL;DR: In this paper, Lu et al. investigated the evolutionary slope of the peak energy in the gamma-ray burst (GRB) spectrum with time during the pulse decay phase and found that the evolutionary slopes are normally distributed for both samples and concentrated around the values of 0.73 and 0.76 for Band and Compton models, respectively.
Journal ArticleDOI
