The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has - together with the PAMELA detection of a rise in the positron fraction up to 100 GeV - motivated many interpretations in terms of dark matter scenarios; alternative explanations assume a nearby electron source like a pulsar or supernova remnant. Here we present a measurement of the cosmic-ray electron spectrum with H.E.S.S. starting at 340 GeV. The H.E.S.S. data with their lower…

The energy spectrum of cosmic electrons measured with the MAGIC telescopes
This thesis seeks to further explore the origin of cosmic electrons and positrons. The unexpected excess of very-high-energy electrons above 100 GeV has been established and is now considered proof

Despite significant progress over more than 100 years, no accelerator has been unambiguously identified as the source of the locally measured flux of cosmic rays. High-energy electrons and positrons
Features in cosmic-ray lepton data unveil the properties of nearby cosmic accelerators
We present a comprehensive discussion about the origin of the features in the leptonic component of the cosmic-ray spectrum. Working in the framework of a up-to-date CR transport scenario tuned on
A review of Cosmic-ray electrons and fermi-LAT
The study of Galactic Cosmic-ray electrons (CREs) saw important developments in recent years, with the assumption of positron production only in interaction of hadronic Cosmic-rays with interstellar
Analysis of the Spectral Intensities and Ratios of Electrons an d Positrons in Cosmic Rays
The observations of the total electronic component and the positron fraction in cosmic rays by the FERMI, HESS, ATIC, and PAMELA in- struments are studied with analytical propagation models, both for
Cosmic ray electrons, positrons and the synchrotron emission of the Galaxy: consistent analysis and implications
A multichannel analysis of cosmic ray electron and positron spectra and of the diffuse synchrotron emission of the Galaxy is performed by using the DRAGON code. This study is aimed at probing the
Analysis of the Positron Fraction and the Spectrum of the Electronic Component in Cosmic Rays
Recently, the PAMELA, FERMI, HESS, and ATIC instruments have discovered interesting spectral features in the positron to total electron ratio and in the total electronic component of cosmic rays at
We investigate the observed spectrum of cosmic ray electrons and positrons from astrophysical sources, especially pulsars, and the physical processes for making the spectrum spiky or smooth via
Search for features in the cosmic-ray electron and positron spectrum measured by the Fermi Large Area Telescope
The Large Area Telescope onboard the Fermi Gamma-ray Space Telescope has collected the largest ever sample of high-energy cosmic-ray electron and positron events. Possible features in their energy


Measurement of the cosmic ray e+ +e- spectrum from 20 GeV to 1 TeV with the Fermi Large Area Telescope.
This work has developed an efficient electron detection strategy which provides sufficient background rejection for measurement of the steeply falling electron spectrum up to 1 TeV and shows that the electron spectrum falls with energy as E-3.0 and does not exhibit prominent spectral features.
Electron Acceleration in Supernova Remnants and Diffuse Gamma Rays above 1 GeV
The recently observed X-ray synchrotron emission from four supernova remnants (SNRs) has strengthened the evidence that cosmic-ray electrons are accelerated in SNRs. We show that if this is indeed
An anomalous positron abundance in cosmic rays with energies 1.5–100 GeV
It is found that the positron fraction increases sharply over much of that range, in a way that appears to be completely inconsistent with secondary sources, and is concluded that a primary source, be it an astrophysical object or dark matter annihilation, is necessary.
Pulsars versus dark matter interpretation of ATIC/PAMELA
In this paper, we study the flux of electrons and positrons injected by pulsars and by annihilating or decaying dark matter in the context of recent ATIC, PAMELA, Fermi, and HESS data. We review the
Observation of an anomalous positron abundance in the cosmic radiation
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matter particle
The most likely sources of high-energy cosmic-ray electrons in supernova remnants
Evidence of nonthermal X-ray emission and TeV gamma rays from supernova remnants (SNRs) have strengthened the hypothesis that primary Galactic cosmic-ray electrons are accelerated in SNRs.
An excess of cosmic ray electrons at energies of 300–800 GeV
An excess of galactic cosmic-ray electrons at energies of ∼300–800 GeV is reported, which indicates a nearby source of energetic electrons, or the electrons could arise from the annihilation of dark matter particles.

VHE (Very High Energy, E>100 GeV) radiation emitted at cosmological distances will pair produce on low-energy diffuse extragalactic background radiation before ever reaching us. This prevents us from
