Binary Millisecond Pulsar Discovery via Gamma-Ray Pulsations
H. J. Pletsch, L. Guillemot, H. Fehrmann +150
Millisecond pulsars, old neutron stars spun-up by accreting matter from a companion star, can reach high rotation rates of hundreds of revolutions per second. Until now, all such "…
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…
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…
Fermi LAT Search for Dark Matter in Gamma-ray Lines and the Inclusive Photon Spectrum
LAT Collaboration, M. Ackermann, M. Ajello +117
Dark matter particle annihilation or decay can produce monochromatic gamma-ray lines and contribute to the diffuse gamma-ray background. Flux upper limits are presented for gamma-r…
Constraints on the Galactic Halo Dark Matter from Fermi-LAT Diffuse Measurements
LAT collaboration, M. Ackermann, M. Ajello +139
We have performed an analysis of the diffuse gamma-ray emission with the Fermi Large Area Telescope in the Milky Way Halo region searching for a signal from dark matter annihilatio…
Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
LAT Collaboration
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of t…
Periodic Emission from the Gamma-ray Binary 1FGL J1018.6-5856
The Fermi LAT Collaboration, M. J. Coe, F. Di Mille +5
Gamma-ray binaries are stellar systems containing a neutron star or black hole with gamma-ray emission produced by an interaction between the components. These systems are rare, ev…
Anisotropies in the diffuse gamma-ray background measured by the Fermi LAT
M. Ackermann, M. Ajello, A. Albert +134
The contribution of unresolved sources to the diffuse gamma-ray background could induce anisotropies in this emission on small angular scales. We analyze the angular power spectrum…
Constraining the High-Energy Emission from Gamma-ray Bursts with Fermi
LAT Collaboration, GBM Collaboration
We examine 288 GRBs detected by the Fermi Gamma-ray Space Telescope's Gamma-ray Burst Monitor (GBM) that fell within the field-of-view of Fermi's Large Area Telescope (LAT) during…
Search for Dark Matter Satellites using the FERMI-LAT
The Fermi LAT Collaboration, M. Ackermann, A. Albert +133
Numerical simulations based on the Lambda-CDM model of cosmology predict a large number of as yet unobserved Galactic dark matter satellites. We report the results of a Large Area…
Limits on Large Extra Dimensions Based on Observations of Neutron Stars with the Fermi-LAT
Bijan Berenji, Elliott Bloom, Johann Cohen-Tanugi
We present limits for the compactification scale in the theory of Large Extra Dimensions (LED) proposed by Arkani-Hamed, Dimopoulos, and Dvali. We use 11 months of data from the Fe…
