The Fermi/LAT Mission: First Scientific Results
Claudia Cecchi (Università di Perugia & INFN)
Seminar Room 3, 15:00
The Large Area Telescope (LAT), one of the two instruments on the Fermi
Gamma-Ray Space Telescope (formerly GLAST, launched June 11, 2008)
is a pair conversion detector designed to study the gamma-ray sky in the energy
range from 20 MeV up to 300 GeV. The greatly improved sensitivity of the LAT
compared with its predecessor experiment, EGRET on the Compton Gamma-Ray
Observatory, together with the uniform and deep sky coverage, provides a
unique capability for studying the gamma-ray Universe. The Fermi Telescope
probes relativistic outflows and acceleration mechanisms in objects such as
supernova remnants, pulsars, active galactic nuclei and gamma ray bursts and
may also shed light in the origin of dark matter. The LAT has detected
many gamma-ray sources and the diffuse emissions of the Milky Way with
unprecedented sensitivity and resolution. After a brief overview of the
instrument and status, I will concentrate on the results obtained on these
topics for the first year of the Fermi/LAT mission.
