The GLAST Burst Monitor (GBM)
نویسنده
چکیده
The selection of the GLAST burst monitor (GBM) by NASA will allow the investigation of the relation between the keV and the MeV-GeV emission from γ-ray bursts. The GBM consists of 12 NaI and 2 BGO crystals allowing a continuous measurement of the energy spectra of γ-ray bursts from ∼ 5 keV to ∼ 30 MeV. One feature of the GBM is its high time resolution for time-resolved γ-ray spectroscopy. Moreover the arrangement of the NaI-crystals allows a rapid on-board location (< 15◦) of a γ-ray burst within a FoV of ∼ 8.6 sr. This position will be communicated to the main instrument of GLAST making follow-up observations at high energies possible.

Correlative Spectral Analysis of Gamma-Ray Bursts using Swift-BAT and GLAST-GBM
We discuss the preliminary results of spectral analysis simulations involving anticipated correlated multiwavelength observations of gamma-ray bursts (GRBs) using Swift’s Burst Alert Telescope (BAT) and the Gamma-Ray Large Area Space Telescope’s (GLAST) Burst Monitor (GLAST-GBM), resulting in joint spectral fits, including characteristic photon energy (
متن کاملThe GLAST Burst Monitor
The next large NASA mission in the field of gamma-ray astronomy, GLAST, is scheduled for launch in 2007. Aside from the main instrument LAT (Large-Area Telescope), a gamma-ray telescope for the energy range between 20 MeV and > 100 GeV, a secondary instrument, the GLAST burst monitor (GBM), is foreseen. With this monitor one of the key scientific objectives of the mission, the determination of ...

We present preliminary results on Gamma Ray Burst (GRB) triggers with the Gamma-ray Large Area Space Telescope (GLAST). After a brief summary of the detector layout, GLAST expected performances on GRB detection are recalled. Status report on the simulation software and preliminary triggers studies are then reported, already showing significant improvement on EGRET results. 1. Description of the...
متن کاملMEASUREMENTS OF GAMMA - RAY BURSTS ( GRBs ) WITH GLAST
One of the scientific goals of the main instrument of GLAST is the study of Gamma-Ray Bursts (GRBs) in the energy range from ∼ 20 MeV to ∼ 300 GeV. In order to extend the energy measurement towards lower energies a secondary instrument, the GLAST Burst Monitor (GBM), will measure GRBs from ∼ 10 keV to ∼ 25 MeV and will therefore allow the investigation of the relation between the keV and the Me...

The Gamma-ray Large Area Space Telescope (GLAST), scheduled to be launched in fall of 2007, is the next generation satellite for high-energy gamma-ray astronomy. The Large Area Telescope (LAT) is a pair conversion telescope built with a high precision silicon tracker, a segmented CsI electromagnetic calorimeter and a plastic anticoincidence shield. The LAT will survey the sky in the energy rang...
