Gamma-Ray Bursts [PDF]

open access: yesStars and Stellar Processes, 2016
Gamma-ray bursts (GRB) are short and intense bursts of $\sim$100 keV$-$1MeV photons, usually followed by long-lasting decaying afterglow emission in a wide range of electromagnetic wavelengths from radio to X-ray and, sometimes, even to GeV gamma-rays ...

Gamma-Ray Burst Progenitors [PDF]

open access: yesSpace Science Reviews, 2016
We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three distinct strands; (i) direct observations of GRBs and their host ...

Gamma- and Cosmic-Ray observations with the GAMMA-400 Gamma-Ray telescope [PDF]

open access: yesAdvances in Space Research, 2022
The future space-based GAMMA-400 gamma-ray telescope will operate onboard the Russian astrophysical observatory in a highly elliptic orbit during 7 years to observe Galactic plane, Galactic Center, Fermi Bubbles, Crab, Vela, Cygnus X, Geminga, Sun, and other regions and measure gamma- and cosmic-ray fluxes.

ON GAMMA-RAY BURSTS [PDF]

open access: yesThe 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 ...

AGILE Gamma-Ray Detection of the Exceptional GRB 221009A

open access: yesThe Astrophysical Journal Letters, 2023
Gamma-ray emission in the MeV–GeV range from explosive cosmic events is of invaluable relevance to understanding physical processes related to the formation of neutron stars and black holes.

The Structure of Gamma Ray Burst Jets

open access: yesGalaxies, 2022
Due to relativistic bulk motion, the structure and orientation of gamma-ray burst (GRB) jets have a fundamental role in determining how they appear.

3HWC: The Third HAWC Catalog of Very-high-energy Gamma-Ray Sources [PDF]

open access: yesAstrophysical Journal, 2020
We present a new catalog of TeV gamma-ray sources using 1523 days of data from the High-Altitude Water Cherenkov (HAWC) Observatory. The catalog represents the most sensitive survey of the northern gamma-ray sky at energies above several TeV, with three ...

Gamma-Ray Bursts [PDF]

open access: yesScience, 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.

The Swift Gamma-Ray Burst Mission [PDF]

open access: yes, 2004
The Swift mission, scheduled for launch in 2004, is a multiwavelength observatory for gamma-ray burst (GRB) astronomy. It is a first-of-its-kind autonomous rapid-slewing satellite for transient astronomy and pioneers the way for future rapid-reaction and
