An enigmatic long-lasting γ-ray burst not accompanied by a bright supernova
- M. D. Valle, G. Chincarini, +14 authors L. Stella
- Physics
- Nature
- 15 August 2006
Gamma-ray bursts (GRBs) are short, intense flashes of soft γ-rays coming from the distant Universe. Long-duration GRBs (those lasting more than ∼2 s) are believed to originate from the deaths of… Expand
Relativistic jet activity from the tidal disruption of a star by a massive black hole
- D. Burrows, J. A. Kennea, +55 authors N. Gehrels
- Physics, Medicine
- Nature
- 1 August 2011
Supermassive black holes have powerful gravitational fields with strong gradients that can destroy stars that get too close, producing a bright flare in ultraviolet and X-ray spectral regions from… Expand
GRB 090423 at a redshift of z ≈ 8.1
- R. Salvaterra, M. D. Valle, +42 authors V. Testa
- Physics, Medicine
- Nature
- 8 June 2009
Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths that they are detectable at… Expand
The X-ray counterpart to the gravitational-wave event GW170817
A long-standing paradigm in astrophysics is that collisions—or mergers—of two neutron stars form highly relativistic and collimated outflows (jets) that power γ-ray bursts of short (less than two… Expand
Design concepts for the Cherenkov Telescope Array CTA: an advanced facility for ground-based high-energy gamma-ray astronomy
- M. Actis, G. Agnetta, +497 authors C. Rulten
- Physics
- 23 November 2011
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has a… Expand
Very-High-Energy Gamma Rays from a Distant Quasar: How Transparent Is the Universe?
- J. Albert, E. Aliu, +146 authors J. Zapatero
- Physics, Medicine
- Science
- 27 June 2008
The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source (in… Expand
Spectroscopic identification of r-process nucleosynthesis in a double neutron-star merger
- E. Pian, P. D'Avanzo, +81 authors D. Vergani
- Physics, Medicine
- Nature
- 16 October 2017
The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of γ-rays, a gravitational-wave signal, and a transient optical–near-infrared source… Expand
MAGIC DISCOVERY OF VERY HIGH ENERGY EMISSION FROM THE FSRQ PKS 1222+21
- J. Aleksić, L. Antonelli, +146 authors S. Buson
- Physics
- 24 January 2011
Very high energy (VHE) gamma-ray emission from the flat spectrum radio quasar (FSRQ) PKS 1222+ 21 (4C 21.35, z = 0.432) was detected with the MAGIC Cherenkov telescopes during a short observation… Expand
SN 2003lw and GRB 031203: A Bright Supernova for a Faint Gamma-Ray Burst
- D. Malesani, G. Tagliaferri, +23 authors K. Nomoto
- Physics
- 23 May 2004
Optical and near-infrared observations of the gamma-ray burst GRB 031203, at z = 0.1055, are reported. A very faint afterglow is detected superposed onto the host galaxy in our first infrared JHK… Expand
