Fermi-LAT observations of the exceptional gamma-ray outbursts of 3C 273 in September 2009
A. A. Abdo et al.
We present the light curves and spectral data of two exceptionally luminous gamma-ray outburts observed by the Large Area Telescope (LAT) experiment on board Fermi Gamma-ray Space…
Search for gamma-ray emission from magnetars with the Fermi Large Area Telescope
LAT collaboration
We report on the search for 0.1-10 GeV emission from magnetars in 17 months of Fermi Large Area Telescope (LAT) observations. No significant evidence for gamma-ray emission from an…
High redshift X-ray cooling-core cluster associated with the luminous radio loud quasar 3C186
Aneta Siemiginowska, D. J. Burke, Thomas L. Aldcroft +5
We present the first results from a new, deep (200ks) Chandra observation of the X-ray luminous galaxy cluster surrounding the powerful (L ~10^47 erg/s), high-redshift (z=1.067), c…
Fermi Large Area Telescope Observations of Misaligned AGN
LAT Collaboration
Analysis is presented on 15 months of data taken with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope for 11 non-blazar AGNs, including 7 FRI radio galaxies a…
Fermi LAT observations of the Geminga pulsar
LAT Collaboration, A. A. Abdo
We report on the \textit{Fermi}-LAT observations of the Geminga pulsar, the second brightest non-variable GeV source in the -ray sky and the first example of a radio-quiet -r…
Fermi Gamma-ray Space Telescope Observations of Recent Gamma-ray Outbursts from 3C 454.3
LAT collaboration
The flat spectrum radio quasar 3C~454.3 underwent an extraordinary outburst in December 2009 when it became the brightest gamma-ray source in the sky for over one week. Its daily f…
