A View of Supernova Remnant CTB 37A with the Fermi Gamma-ray Space Telescope [PDF]

Adv.Space Res. 51 (2013) 247-252, 2013
Supernovae and their remnants have long been favored as cosmic ray ac- celerators. Recent data from the Fermi Gamma-ray Space Telescope has given us an improved window into such sources, including the remnant CTB 37A. Using the Fermi Large Area Telescope, we found significant gamma-ray emission coincident with the remnant, which also emits in radio, X ...

Fermi Gamma-ray Space Telescope: High-Energy Results from the First Year [PDF]

Rept.Prog.Phys.73:074901,2010, 2010
The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-of-view pair-conversion telescope covering the energy range from 20 MeV to more than 300 GeV, is the primary instrument on Fermi.

Searching for the most distant blazars with the Fermi Gamma-ray Space Telescope [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We investigate the prospects for discovering blazars at very high-redshifts (z>3-6) with the Fermi Gamma-Ray Space Telescope (Fermi), employing a model for the evolving gamma-ray luminosity function (GLF) of the blazar population. Our previous GLF model is used as a basis, which features luminosity-dependent density evolution implied from X-ray data on

Gamma-ray band and multi-waveband variability of blazars with the Fermi Large Area Space Telescope [PDF]

arXiv, 2011
The Fermi Gamma-ray Space Telescope, as an all-sky survey and monitoring mission, is producing daily/weekly sampled gamma-ray light curves for dozens of blazars and other high-energy sources. Highlights on MeV-GeV gamma-ray variability properties of these sources are reported together with a few remarks about some multi-waveband observing campaigns led

Twelve Years of Education and Public Outreach with the Fermi Gamma-ray Space Telescope [PDF]

arXiv, 2013
During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has supported a wide range of Education and Public Outreach (E/PO) activities, targeting K-14 students and the general public. The purpose of the Fermi E/PO program is to increase student and public understanding of the science of the high-energy Universe, through inspiring, engaging ...

The multi-faceted synergy between Swift and Fermi in radio-loud AGN studies [PDF]

arXiv, 2015
Since its launch in 2008 June, the Fermi Gamma-ray Space Telescope has opened a new era in high-energy astrophysics. The unprecedented sensitivity, angular resolution and effective area of the Large Area Telescope on board Fermi, together with the nearly continuous observation of the entire gamma-ray sky assures a formidable opportunity to study in ...

Fermi observations of high-energy gamma-ray emission from GRB 080825C [PDF]

Astrophys.J.707:580-592,2009, 2009
The Fermi Gamma-ray Space Telescope (FGST) has opened a new high-energy window in the study of Gamma-Ray Bursts (GRBs). Here we present a thorough analysis of GRB 080825C, which triggered the Fermi Gamma-ray Burst Monitor (GBM), and was the first firm detection of a GRB by the Fermi Large Area Telescope (LAT).

A 34.5 day quasi-periodic oscillation in γ-ray emission from the blazar PKS 2247–131 [PDF]

Nature Communications, 2018
PKS 2247–131 is an active galaxy that has been emitting gamma-ray flares since October 2016. Here, the authors used data obtained with the Fermi Gamma-ray Space Telescope to find that PKS 2247–131 presents a relatively short, month-like flux oscillation ...

Observations of the Large Magellanic Cloud with Fermi [PDF]

arXiv, 2009
We report on observations of the Large Magellanic Cloud with the Fermi Gamma-Ray Space Telescope. The LMC is clearly detected with the Large Area Telescope (LAT) and for the first time the emission is spatially well resolved in gamma-rays. Our observations reveal the massive star forming region 30 Doradus as a bright source of gamma-ray emission in the
