    I will summarize the evidence in support of, and in opposition to, pulsars as the source of the gamma-ray excess observed from the Inner Milky Way. The evidence in favor of a pulsar origin includes the observed small scale power in the gamma-ray emission from this region, and possible correlations between this emission and the distribution of stars. In opposition to this conclusion are the...

    Talk

    Recent HAWC observations have found extended TeV emission coincident with the Geminga and Monogem pulsars. In this talk, I will show that these detections have significant implications for our understanding of the TeV gamma-ray sky. First, the spectrum and intensity of these TeV Halos indicates that a large fraction of the pulsar spindown energy is efficiently converted into electron-positron...

    Talk

    The so-called Fermi-excess in the diffuse Galactic gamma-ray sky is observed as a shift of the maximum in the E^2 weighted gamma-ray spectrum from 0.7 GeV to around 2 GeV. Such a shift can be explained by the contribution of a new source with a spectrum peaking at 2 GeV. Three sources have been proposed: a dark matter (DM) annihilation signal, a signal from millisecond pulsars (MSPs), a...

  4. 158. Martin Winkler (NORDITA): Hunting for WIMPs with Charged Cosmic Rays

    Talk

    Weakly Interacting Massive Particles (WIMPs) have been the target of cosmic ray experiments for decades. AMS-02 is the first experiment which can realistically probe WIMP annihilation signals in the antiproton channel. Due to the tiny experimental errors, uncertainties in the astrophysical background have become the most limiting factor for dark matter detection. I will use the combination of...

    Talk

    GAPS (General Antiparticle Spectrometer) is a balloon-based indirect dark matter search experiment that focuses on low-energy antiprotons and antideuterons produced by dark matter annihilation and decay in the Galactic halo. The predicted antideuteron flux from well-motivated dark matter models can be more than two orders of magnitude larger than the one produced by the cosmic-ray interaction...
