Science, 2012 Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.

A Roadmap to Gamma-Ray Bursts: New Developments and Applications to Cosmology
Galaxies, 2021 Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to z≃9. In this short review, we first discuss gamma-ray burst classification and morphological properties.

Gamma-Ray Burst Afterglows [PDF]
Annual Review of Astronomy and Astrophysics, 2000 ▪ Abstract The discovery of counterparts in X-ray and optical to radio wavelengths has revolutionized the study of γ-ray bursts, until recently the most enigmatic of astrophysical phenomena. We now know that γ-ray bursts are the biggest explosions in nature, caused by the ejection of ultrarelativistic matter from a powerful energy source and its ...

Particles, Strings and Cosmology (PASCOS 99), 2000 Ultra-high-energy, >10^19 eV, cosmic-ray and high energy, ~10^14 eV, neutrino production in GRBs is discussed in the light of recent GRB and cosmic-ray observations. Emphasis is put on model predictions that can be tested with operating and planned cosmic-ray and neutrino detectors, and on the prospects of testing for neutrino properties.

Gamma-Ray Bursts at TeV Energies: Observational Status
Galaxies, 2022 Gamma-ray bursts (GRBs) are some of the most energetic events in the Universe and are potential sites of cosmic ray acceleration up to the highest energies.

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 ...

Stripping Model for Short Gamma-Ray Bursts in Neutron Star Mergers
Particles, 2022 We overview the current status of the stripping model for short gamma-ray bursts. After the historical joint detection of the gravitational wave event GW170817 and the accompanying gamma-ray burst GRB170817A, the relation between short gamma-ray bursts ...

Outliers in Spectral Time Lag-Selected Gamma Ray Bursts
Universe, 2022 It is possible that astrophysical samples are polluted by some outliers, which might belong to a different sub-class. By removing the outliers, the underlying statistical features may be revealed.

GECAM Localization of High-energy Transients and the Systematic Error
The Astrophysical Journal Supplement Series, 2023 The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a pair of microsatellites (i.e., GECAM-A and GECAM-B) dedicated to monitoring gamma-ray transients including the high-energy electromagnetic counterparts of ...

The Eleventh Marcel Grossmann Meeting, 2008 (Shortened) We show by example how the uncoding of Gamma-Ray Bursts (GRBs) offers unprecedented possibilities to foster new knowledge in fundamental physics and in astrophysics. After recalling some of the classic work on vacuum polarization in uniform electric fields by Klein, Sauter, Heisenberg, Euler and Schwinger, we summarize some of the efforts ...
