The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
Fermi LAT study of cosmic-rays and the interstellar medium in nearby molecular clouds
LAT collaboration
We report an analysis of the interstellar gamma-ray emission from the Chamaeleon, R Coronae Australis (R CrA), and Cepheus and Polaris flare regions with the Fermi Large Area Teles…
Gamma-ray observations of the Orion Molecular Clouds with the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +142
We report on the gamma-ray observations of giant molecular clouds Orion A and B with the Large Area Telescope (LAT) on-board the Fermi Gamma-ray Space Telescope. The gamma-ray emis…
Search for Spatially Extended Fermi-LAT Sources Using Two Years of Data
Joshua Lande, Markus Ackermann, Alice Allafort +10
Spatial extension is an important characteristic for correctly associating gamma-ray-emitting sources with their counterparts at other wavelengths and for obtaining an unbiased mod…
GeV Observations of Star-forming Galaxies with \textit{Fermi} LAT
Fermi LAT Collaboration, M. Ackermann, M. Ajello +127
Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies comp…
The Fermi Large Area Telescope On Orbit: Event Classification, Instrument Response Functions, and Calibration
LAT Collaboration
The Fermi Large Area Telescope (Fermi-LAT, hereafter LAT), the primary instrument on the Fermi Gamma-ray Space Telescope (Fermi) mission, is an imaging, wide field-of-view, high-en…
