GRB 040403: a faint X-ray rich Gamma-ray Burst discovered by INTEGRAL
S. Mereghetti, D. Gotz, M. I. Andersen +13
GRB 040403 is one of the faintest gamma-ray bursts for which a rapid and accurate localization has been obtained. Here we report on the gamma-ray properties of this burst, based on…
INTEGRAL/SPI Limits on Electron-Positron Annihilation Radiation from the Galactic Plane
B. J. Teegarden, K. Watanabe, P. Jean +24
The center of our Galaxy is a known strong source of electron-positron 511-keV annihilation radiation. Thus far, however, there have been no reliable detections of annihilation rad…
The host of GRB 030323 at z=3.372: a very high column density DLA system with a low metallicity
P. M. Vreeswijk, S. L. Ellison, C. Ledoux +29
We present photometry and spectroscopy of the afterglow of GRB 030323. VLT spectra of the afterglow show damped Lya (DLA) absorption and low- and high-ionization lines at a redshif…
