Title:     Early Results from Fermi's (nee GLAST) First Six Months in Orbit

Abstract: The Fermi Gamma-ray Space Telescope (FGST, formerly GLAST) is a next generation high energy gamma-ray observatory that launched in June 2008, and and underwent a 60 day commissioning period. 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. The LAT has better angular resolution, greater effective area, wider field of view and broader energy coverage than any previous experiment in this energy range. The LAT's scanning mode provides unprecedented uniformity of sky coverage and permits measurements of light curves for any source. The GLAST Burst Monitor (GBM) is the secondary instrument, comprised of NaI and BGO crystals, and covers the energy range 8 keV-30 MeV. The GBM is designed to provide supplemental observations of transients, such as solar flares.  Early results on new pulsar classes, gamma-ray bursts (GRBs), active galactic nuclei (SGNs) and galactic binary systems will be presented, as well as some details on operations and life in a mixed astro and particle physics community.

Stimulants available 15 minutes before the talk.
