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…
Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state
M. Ackermann, M. Ajello, J. Ballet +208
The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuou…
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…
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…
Optimization of the Collection Efficiency of a Hexagonal Light Collector using Quadratic and Cubic Bézier Curves
Akira Okumura
Reflective light collectors with hexagonal entrance and exit apertures are frequently used in front of the focal-plane camera of a very-high-energy gamma-ray telescope to increase…
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…
