Gamma-ray bursters at cosmological distances
The Astrophysical Journal, 1986 It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy of about 10 to the 51st ergs within less than 1 s, making gamma-ray bursters the brightest objects known in the universe, many orders of magnitude brighter ...

Afterglows from gamma-ray bursters - A way to estimate the burster distance scale?
The Astrophysical Journal, 1993 We calculate the strength of secondary gamma-ray signals that could be produced by positron annihilation in a medium surrounding a gamma-ray burster. We predict that such signals should be observable for a fairly wide range of conditions of this medium for bursts at both Galactic and cosmological distances.

Outburst of the X-ray transient SAX J1818.6-1703 detected by INTEGRAL in September 2003
, 2005 During the observation of the Galactic-center field by the INTEGRAL observatory on September 9, 2003, the IBIS/ISGRI gamma-ray telescope detected a short (several-hours-long) intense (~380 mCrab at the peak) outburst of hard radiation from the X-ray ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an
