Journal ArticleDOI

Searching for dark matter annihilation from Milky Way dwarf spheroidal galaxies with six years of Fermi Large Area Telescope data

Markus Ackermann, +125 more
- 09 Mar 2015 - 
TL;DR: In this article, the authors report on γ-ray observations of the Milky-Way satellite galaxies (dSphs) based on six years of Fermi Large Area Telescope data processed with the new Pass8 event-level analysis.
Journal ArticleDOI

The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV

Markus Ackermann, +143 more
- 14 Oct 2014 - 
TL;DR: The IGRB spectrum shows a significant high-energy cutoff feature, and can be well described over nearly four decades in energy by a power law with exponential cutoff having a spectral index of $2.32\pm0.02$ and a break energy of $(279\pm52)$ GeV using our baseline diffuse Galactic emission model as mentioned in this paper.
Journal ArticleDOI

The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV

Markus Ackermann, +177 more
- 20 Jan 2015 - 
TL;DR: The first IGRB measurement with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) used 10 months of sky-survey data and considered an energy range between 200 MeV and 100 GeV.
Journal ArticleDOI

Constraining Dark Matter Models from a Combined Analysis of Milky Way Satellites with the Fermi Large Area Telescope

Markus Ackermann, +156 more
- 08 Dec 2011 - 
TL;DR: This work presents a search for dark matter consisting of weakly interacting massive particles, applying a joint likelihood analysis to 10 satellite galaxies with 24 months of data of the Fermi Large Area Telescope, and is able to rule out models with the most generic cross section, using gamma rays.
Journal ArticleDOI

The fermi large area telescope on orbit: Event classification, instrument response functions, and calibration

Markus Ackermann, +223 more
- 12 Oct 2012 - 
TL;DR: 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-energy \gamma-ray telescope, covering the energy range from 20 MeV to more than 300 GeV as discussed by the authors.
