A possible macronova in the late afterglow of the long–short burst GRB 060614
TLDR
The discovery of near-infrared bump that is significantly above the regular decaying afterglow is reported, which is inconsistent with even the weakest known supernova.
Gamma‐ray burst efficiency and possible physical processes shaping the early afterglow
The discovery by Swift that a good fraction of gamma-ray bursts (GRBs) have a slowly decaying X-ray afterglow phase led to the suggestion that energy injection into the blast wave takes place several
Possible Dark Matter Annihilation Signal in the AMS-02 Antiproton Data.
TLDR
Using the latest AMS-02 cosmic-ray antiproton flux data, it is found that a dark matter signal is favored and incorporated into the model self-consistently under a Bayesian framework.
Fast radio bursts as a cosmic probe
We discuss the possibility of using fast radio bursts (FRBs)-if cosmological-as a viable cosmic probe. We find that the contribution of the host galaxies to the detected dispersion measures can be
A COMPREHENSIVE ANALYSIS OF FERMI GAMMA-RAY BURST DATA. I. SPECTRAL COMPONENTS AND THE POSSIBLE PHYSICAL ORIGINS OF LAT/GBM GRBs
We present a systematic analysis of the spectral and temporal properties of 17 gamma-ray bursts (GRBs) codetected by the Gamma-ray Burst Monitor (GBM) and the Large Area Telescope (LAT) onboard the
The Light Curve of the Macronova Associated with the Long-Short Burst GRB 060614
The Swift-detected GRB 060614 was a unique burst that straddles an imaginary divide between long- and short-duration gamma-ray bursts (GRBs), and its physical origin has been heavily debated over the
The X-ray afterglow flat segment in short GRB 051221A: Energy injection from a millisecond magnetar?
The flat segment, lasting similar to 10(4) s, in the X-ray afterglow of GRB 051221A represents the first clear case of strong energy injection in the external shock of a short gamma-ray burst (GRB)
Signature of gravitational wave radiation in afterglows of short gamma-ray bursts?
Short gamma-ray bursts (GRBs), brief intense emission of gamma rays characterized by a duration shorter than 2 s that are plausibly powered by the coalescence of binary neutron stars, are believed to
GRB 120422A: A LOW-LUMINOSITY GAMMA-RAY BURST DRIVEN BY A CENTRAL ENGINE
GRB 120422A is a low-luminosity gamma-ray burst (GRB) associated with a bright supernova, which distinguishes itself by its relatively short T-90 (similar to 5 s) and an energetic and steep-decaying
The Macronova in GRB 050709 and the GRB-macronova connection
TLDR
A reanalysis of the publicly available data of this event and the discovery of a Li-Paczynski macronova/kilonova that dominates the optical/infrared signal at t>2.5 days supports the suggestion that compact binary mergers are significant and possibly main sites of heavy r-process nucleosynthesis.
