First light from the Vela pulsar with the Fermi Gamma-ray Space Telescope
AIP Conference Proceedings, 2009The Fermi Gamma‐ray Space Telescope, launched in June 2008, is an international space mission entirely devoted to the study of the high‐energy gamma rays from the Universe. The main instrument aboard Fermi is the Large Area Telescope (LAT), a pair conversion telescope equipped with the state‐of‐the art in gamma‐ray detectors technology.

Status of the technology of the current space missions including the Fermi gamma-ray space telescope
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2010Abstract We review the status of X-rays and γ -rays space missions operational in 2009. We provide highlights of the current semiconductor technology instrumentation and briefly discuss challenges to be addressed by future missions.

Fermi Gamma-ray Space Telescope, Introduction and Highlights from the First Eight Months
AIP Conference Proceedings, 2009The Fermi Gamma‐ray Space Telescope, formerly named GLAST, is a mission in low‐Earth orbit to observe gamma rays from the cosmos in the broad energy range from 20 MeV to >300 GeV, with supporting observations of gamma‐ray bursts from 8 keV to 30 MeV. The telescope far surpasses previous generations in its ability to detect and localize faint gamma‐ray ...

Some highlights of the first four years of the Fermi Gamma-ray Space Telescope
Frontiers of Physics, 2013The Fermi Gamma-ray Space Telescope, formerly called GLAST, measures the cosmic gamma-ray flux in the energy range 8 keV to > 300 GeV. In addition to breakthrough capabilities in energy coverage and localization, the very large field of view enables observations of 20% of the sky at any instant, and the entire sky on a timescale of a few hours.

The flat-spectrum radio quasar 3C 454.3 underwent an extraordinary 5-day gamma-ray outburst in November 2010 where the daily flux measured with the Fermi Large Area Telescope (LAT) at photon energies E>100 MeV reached (66+/-2) x 10^-6 ph cm^-2 s^-1. The 3-hr peak flux corresponded to an apparent isotropic luminosity of (2.1+/-0.2)x10^50 erg s^-1, the ...
