Title:
The Fermi Gamma-ray Telescope Status, Early Results and Prospects
Date: Thursday, October 2nd, 2008
Time: 12:00
Venue: Villa Bazzoni

Abstract:
The Fermi Gamma-Ray Space Telescope is a satellite-based
observatory that will study the gamma-ray sky in a wide energy range
from a few keV to 300 GeV, allowing the investigation of many fields
of the gamma ray astrophysics. Fermi will open a new and important
window on a wide variety of phenomena, including black holes and
active galactic nuclei, gamma-ray bursts, the origin of cosmic rays
and supernova remnants and searches for hypothetical new phenomena
such as supersymmetric dark matter annihilations.
Fermi was launched in June 2008 from Kennedy Space Flight Centre (NASA).
The primary instrument is the Large Area Telescope (LAT), which
measures gamma-ray flux and spectra from 20 MeV to > 300 GeV and is a
successor to the highly successful EGRET experiment on CGRO and the
Italian space Agency Small Mission AGILE. The LAT has better angular
resolution, greater effective area, wider field of view and broader
energy coverage with respect to EGRET.
In an early phase of the Fermi operations, a series of calibrations
and performance measurements and monitoring will be performed and
first sky images were collected. In this talk a review of the Fermi
physics and the first sky images and early results will be presented.
