Dark gamma-ray bursts [PDF]

Physical Review D, 2017
Many theories of dark matter (DM) predict that DM particles can be captured by stars via scattering on ordinary matter. They subsequently condense into a DM core close to the center of the star and eventually annihilate. In this work, we trace DM capture and annihilation rates throughout the life of a massive star and show that this evolution ...

Unveiling the engines of fast radio bursts, superluminous supernovae, and gamma-ray bursts [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Young, rapidly spinning magnetars are invoked as central engines behind a diverse set of transient astrophysical phenomena, including gamma-ray bursts (GRB), super-luminous supernovae (SLSNe), fast radio bursts (FRB), and binary neutron star (NS) mergers.

A Study of the Overall Evolution Behaviors of Pulses and Flares within Gamma-Ray Bursts

The Astrophysical Journal, 2023
Many studies have shown that the X-ray flares in gamma-ray bursts (GRBs) have similar properties to the prompt emission pulses that occur in GRBs, suggesting that they may come from the same origin. We attempt to extend the evolution behavior that exists

Gamma-Ray Bursts

Stars and Stellar Processes, 2016
Gamma-ray bursts (GRBs) are short periods of γ-rays (high energy light waves) that are detected on Earth. They were originally detected by satellites that were designed to watch for nuclear weapons tests on Earth. GRBs are difficult to study because they

Model Constraints Based on the IceCube Neutrino Nondetection of GRB 221009A

The Astrophysical Journal, 2023
GRB 221009A is a bright gamma-ray burst (GRB) with isotropic energy larger than 10 ^54 erg. Its fairly low redshift makes it a promising candidate for high-energy neutrino detection.
