A Warning on the GeV-TeV Connection in Blazars
L. Costamante
Fermi-LAT spectra at high energies (HE, 0.1-100 GeV) are often extrapolated to very high energies (VHE, >100 GeV) and considered either a good estimate or an upper limit for the bl…
On the correct intrinsic VHE properties of the BL Lac H 2356-309
L. Costamante
The high-energy-peaked BL Lac H 2356-309 (z=0.165) was detected by HESS at very high energies (VHE, >100 GeV) with relatively high significance in the years 2004-2007, allowing a g…
Discovery of VHE and HE emission from the blazar 1ES 0414+009 with H.E.S.S and Fermi-LAT
F. Volpe, S. Ohm, M. Hauser +5
The high energy peaked BL Lac (HBL) object 1ES 0414+009 (z=0.287) is a distant very high-energy (VHE, E > 100 GeV) blazars with well-determined redshift. This source was detected w…
Gamma-ray flares from the Crab Nebula
LAT Collaboration
A young and energetic pulsar powers the well-known Crab Nebula. Here we describe two separate gamma-ray (photon energy >100 MeV) flares from this source detected by the Large Area…
Bright AGN Source List from the First Three Months of the Fermi Large Area Telescope All-Sky Survey
A. A. Abdo
The first three months of sky-survey operation with the Fermi Gamma Ray Space Telescope (Fermi) Large Area Telescope (LAT) reveals 132 bright sources at |b|>10 deg with test statis…
Fermi Large Area Telescope Bright Gamma-ray Source List
A. A. Abdo
Following its launch in June 2008, the Fermi Gamma-ray Space Telescope (Fermi) began a sky survey in August. The Large Area Telescope (LAT) on Fermi in 3 months produced a deeper a…
