Recent observations by PAMELA, Fermi-LAT, and AMS-02 have conclusively indicated a rise in the cosmic-ray positron fraction above 10 GeV, a feature which is impossible to mimic under the paradigm of secondary positron production with self-consistent Galactic cosmic-ray propagation models. A leading explanation for the positron fraction rise is an additional source of electron-positron pairs, for example one or more mature, energetic, and relatively nearby pulsars. We point out that any one of…

Circular Polarization of Pulsar Wind Nebulae and the Cosmic-Ray Positron Excess
Recent observations by the PAMELA and AMS-02 telescopes have uncovered an anomalous rise in the positron fraction at energies above 10~GeV. One possible explanation for this excess is the production
Features in the spectrum of cosmic-ray positrons from pulsars
Pulsars have been invoked to explain the origin of recently observed high-energy Galactic cosmic-ray positrons. Since the positron propagation distance decreases with energy, the number of pulsars
A new look at the cosmic ray positron fraction
The positron fraction in cosmic rays was found to be a steadily increasing in function of energy, above $\sim$ 10 GeV. This behaviour contradicts standard astrophysical mechanisms, in which
Measurement of the large scale anisotropy in cosmic ray electrons, positrons and protons with the AMS-02 detector on the ISS
The field of astroparticle physics started with the discovery of cosmic rays in 1912 by Victor Hess. Cosmic rays, which initially led to important advances in the field of Particle Physics, provide
Can we explain AMS-02 antiproton and positron excesses simultaneously by nearby supernovae without pulsars or dark matter?
We explain the excess of the antiproton fraction recently reported by the AMS-02 experiment by considering collisions between cosmic-ray protons accelerated by a local supernova remnant and the
HAWC Observations Strongly Favor Pulsar Interpretations of the Cosmic-Ray Positron Excess
Recent measurements of the Geminga and B0656+14 pulsars by the gamma-ray telescope HAWC (along with earlier measurements by Milagro) indicate that these objects generate significant fluxes of very
Interpretation of the cosmic ray positron and electron excesses with an annihilating-decaying dark matter scenario
The precise measurements of energy spectra of cosmic ray positrons and/or electrons by recent experiments show clear excesses above 10 GeV. Moreover, a potential sharp spectral feature was suggested
Cosmic-ray positrons from millisecond pulsars
Observations by the Fermi Large Area Telescope of gamma-ray millisecond pulsar light curves imply copious pair production in their magnetospheres, and not exclusively in those of younger pulsars.
Discriminating local sources of high-energy cosmic electrons and positrons by current and future anisotropy measurements
The Fermi-LAT detects no significant anisotropy of the cosmic-ray (CR) electrons and positrons ($e^-+e^+$) with seven years of data, which provides the strongest restriction to the $e^-+e^+$
Stochastic nature of Galactic cosmic-ray sources
The precision measurements of the spectra of cosmic ray nuclei and leptons in recent years have revealed the existence of multiple features, such as the spectral break at ∼ 300 GV rigidity seen by


Pulsars as the sources of high energy cosmic ray positrons
Recent results from the PAMELA satellite indicate the presence of a large flux of positrons (relative to electrons) in the cosmic ray spectrum between approximately 10 and 100 GeV. As annihilating
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.
Galactic electrons and positrons at the Earth: new estimate of the primary and secondary fluxes
Context. The so-called excess of cosmic ray (CR) positrons observed by the PAMELA satellite up to 100 GeV has led to many interpretation attempts, from standard astrophysics to a possible exotic
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
Constraints on dark matter annihilation in clusters of galaxies with the Fermi large area telescope
Nearby clusters and groups of galaxies are potentially bright sources of high-energy gamma-ray emission resulting from the pair-annihilation of dark matter particles. However, no significant
The Contribution of Fermi Gamma-Ray Pulsars to the local Flux of Cosmic-Ray Electrons and Positrons
We analyze the contribution of gamma-ray pulsars from the first Fermi-Large Area Telescope (LAT) catalogue to the local flux of cosmic-ray electrons and positrons (e+e-). We present new distance
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.
Measurement of the Anisotropy of Cosmic Ray Arrival Directions with IceCube
We report the first observation of an anisotropy in the arrival direction of cosmic rays with energies in the multi-TeV region in the Southern sky using data from the IceCube detector. Between 2007
