Dark matter electron anisotropy: A universal upper limit

  title={Dark matter electron anisotropy: A universal upper limit},

We study the dipole anisotropy in the arrival directions of high energy CR electrons and positrons (CRE) of dark matter (DM) origin. We show that this quantity is very weakly model dependent and offers a viable criterion to discriminate among CRE from DM or from local discrete sources, like e.g. pulsars. In particular, we find that the maximum anisotropy which DM can provide is to a very good approximation a universal quantity and, as a consequence, if a larger anisotropy is detected, this… Expand

Solution to the cosmic ray anisotropy problem.
It is found that if the field direction and the gradient direction are close to ∼90°, the dipole amplitude is considerably suppressed and can be reconciled with observations, which sheds light on a long-standing problem. Expand
A solution to the cosmic ray anisotropy problem
Abstract. Observations of the cosmic ray (CR) anisotropy are widely advertised as a means of finding nearby sources. This idea has recently gained currency after the discovery of a rise in theExpand
An observable electron-positron anisotropy cannot be generated by dark matter
I demonstrate that if an anisotropy in the arrival direction of high-energy cosmic-ray electrons and positrons is observed then, barring local anisotropic diffusion, dark matter annihilation is ruledExpand
Dynamical Dark Matter and the positron excess in light of AMS results
The AMS-02 experiment has recently released data which confirms a rise in the cosmic-ray positron fraction as a function of energy up to approximately 350 GeV. Over the past decade, attempts toExpand
Searching for Anisotropies in the Arrival Directions of Electromagnetic Air Showers at TeV energies with H.E.S.S.
The measurements of cosmic-ray electrons and positrons with PAMELA (Adriani et al. 2009), Fermi-LAT (Ackermann et al. 2012) and AMS-02 (Aguilar et al. 2013) have established the existence of anExpand
Indirect and direct search for dark matter
The majority of the matter in the universe is still unidentified and under investigation by both direct and indirect means. Many experiments searching for the recoil of dark-matter particles offExpand
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 energyExpand
Observing small-scale $\gamma$-ray anisotropies with the Cherenkov Telescope Array
Disentangling the composition of the diffuse gamma-ray background (DGRB) is a major challenge in gamma-ray astronomy. It is presumed that at the highest energies, the DGRB is dominated by relativelyExpand
The Expectation of the Energy Spectrum of Cosmic-Ray Electrons with LHAASO
The high-energy electrons suffer severe energy loss during their propagation, owing to the Synchrotron and Inverse-Compton processes. Thus, the electrons exceeding TeV are most likely originatingExpand

High energy positrons from annihilating dark matter
We also consider a range of diffusion parameters consistent with current cosmic ray data. We find that a significant upturn in the positron fraction above 10 GeV is compatible with a wide range ofExpand

The contribution to the antimatter flux from individual dark matter substructures
The local antimatter fluxes induced by an individual dark matter (DM) substructure can be significantly dependent on the proper motion of the source. We derive analytic solutions to the propagationExpand
