Gamma-ray bursts (GRBs) are among the most violent occurrences in the universe. They are powerful explosions, visible to high redshift, and thought to be the signature of black hole birth. They are highly luminous events and provide excellent probes of the distant universe. GRB research has greatly advanced over the past 10 years with the results from Swift, Fermi and an active followup community. In this review we survey the interplay between these recent observations and the theoretical… 
Gamma-Ray Burst Prompt Correlations
The mechanism responsible for the prompt emission of gamma-ray bursts (GRBs) is still a debated issue. The prompt phase-related GRB correlations can allow discriminating among the most plausible
Detailed polarization measurements of the prompt emission of five gamma-ray bursts
Gamma-ray bursts (GRBs) are the strongest explosions in the Universe since the Big Bang. They are believed to be produced either in the formation of black holes at the end of massive star
Gamma-Ray Bursts: Characteristics and Prospects
Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. They have remained the object of intense research ever since their discovery was declassified in the early 1970s. Several
Plasmas in Gamma-Ray Bursts: Particle Acceleration, Magnetic Fields, Radiative Processes and Environments
Being the most extreme explosions in the universe, gamma-ray bursts (GRBs) provide a unique laboratory to study various plasma physics phenomena. The complex light curve and broad-band, non-thermal
Search for High-Energy Neutrino Production in Short Gamma Ray Bursts with the IceCube Neutrino Observatory
The Universe is still full of not yet or not fully understood processes. Among all these phenomena, the Gamma-Ray Bursts (GRBs) are among the most impressive ones. The GRBs are the most luminous
Fermi-LAT Observations of the Gamma-Ray Burst GRB 130427A
TLDR
Temporal and spectral analyses of GRB 130427A challenge the widely accepted model that the nonthermal high-energy emission in the afterglow phase of GRBs is synchrotron emission radiated by electrons accelerated at an external shock.
Early GRB Afterglows from Reverse Shocks in Ultra-relativistic, Long-lasting Winds
We develop a model of early Gamma-Ray Burst (GRB) afterglows with dominant X-ray contribution from the reverse shock (RS) propagating in highly relativistic (Lorentz factor γw ∼ 106) magnetized wind
Origin of Sub-TeV Afterglow Emission from Gamma-Ray Bursts GRB 190114C and GRB 180720B
The detection of GRB 180722B and GRB 190114C in sub-TeV gamma-rays has opened up a new window to study gamma-ray bursts in high-energy gamma-rays. Recently it has been shown that the synchrotron and

The observation of Gamma-ray bursts (GRBs) can be classified into prompt and afterglow emission. The prompt emission is observed for up to 100s of seconds after the trigger of the event while a
Gamma-ray bursts and their relation to astroparticle physics and cosmology
This article gives an overview of gamma-ray bursts (GRBs) and their relation to astroparticle physics and cosmology. GRBs are the most powerful explosions in the universe that occur roughly once per

SWIFT AND FERMI OBSERVATIONS OF THE EARLY AFTERGLOW OF THE SHORT GAMMA-RAY BURST 090510
We present the observations of GRB090510 performed by the Fermi Gamma-Ray Space Telescope and the Swift observatory. This is a bright, short burst that shows an extended emission detected in the GeV
Gamma-ray bursts and their links with supernovae and cosmology
Gamma-ray bursts are the most luminous explosions in the Universe, whose origin and mechanism are the focus of intense interest. They appear connected to supernova remnants from massive stars or the

Bright X-ray Flares in Gamma-Ray Burst Afterglows
TLDR
Two bright x-ray flares in GRB afterglows, including a giant flare comparable in total energy to the burst itself, each peaking minutes after the burst, imply that the central engines of the bursts have long periods of activity.
Optical and Long-Wavelength Afterglow from Gamma-Ray Bursts
We discuss the evolution of cosmological gamma-ray burst remnants, consisting of the cooling and expanding fireball ejecta together with any swept-up external matter, after the gamma-ray event. We
FERMI DETECTION OF DELAYED GeV EMISSION FROM THE SHORT GAMMA-RAY BURST 081024B
We report on the detailed analysis of the high-energy extended emission from the short gamma-ray burst (GRB) 081024B detected by the Fermi Gamma-ray Space Telescope. Historically, this represents the
Neutrino Afterglow from Gamma-Ray Bursts: ~1018 eV
We show that a significant fraction of the energy of a γ-ray burst (GRB) is probably converted to a burst of 1017-1019 eV neutrinos and multiple GeV γ-rays that follow the main GRB by ~10 s. If GRBs
Gamma-ray bursts in the Swift era
Gamma-ray burst (GRB) research has undergone a revolution in the last two years. The launch of Swift, with its rapid slewing capability, has greatly increased the number and quality of GRB
A γ-ray burst at a redshift of z ≈ 8.2
Long-duration γ-ray bursts (GRBs) are thought to result from the explosions of certain massive stars, and some are bright enough that they should be observable out to redshifts of z > 20 using
The Early X-Ray Emission from GRBs
TLDR
Observations of the early X-ray emission for a sample of 40 gamma-ray bursts obtained using the Swift satellite, for which the narrow-field instruments were pointed at the burst within 10 minutes of the trigger, show that theX-ray light curve can be well described by an exponential that relaxes into a power law.
