On the progressive hardening of the cosmic-ray proton spectrum in the inner Galaxy
Mart Pothast, Daniele Gaggero, Emma Storm +1
Spatial variations of the average properties that characterize the hadronic component of the diffuse Galactic cosmic-ray sea, in particular the spectral slope and normalization, ma…
Galactic Binaries Can Explain the Fermi Galactic Center Excess and 511 keV Emission
Richard Bartels, Francesca Calore, Emma Storm +1
The Fermi-LAT Galactic Center excess and the 511 keV positron-annihilation signal from the inner Galaxy bare a striking morphological similarity. We propose that both can be explai…
XMM-Newton Observations of the Southeastern Radio Relic in Abell 3667
Emma Storm, Jacco Vink, Fabio Zandanel +1
Radio relics, elongated, non-thermal, structures located at the edges of galaxy clusters, are the result of synchrotron radiation from cosmic-ray electrons accelerated by merger-dr…
The Fermi-LAT GeV Excess Traces Stellar Mass in the Galactic Bulge
Richard Bartels, Emma Storm, Christoph Weniger +1
An anomalous emission component at energies of a few GeV and located towards the inner Galaxy is present in the Fermi-LAT data. It is known as the Fermi-LAT GeV excess. Using almos…
Multiwavelength Analysis of Dark Matter Annihilation and RX-DMFIT
Alex McDaniel, Tesla Jeltema, Stefano Profumo +1
Dark matter (DM) particles are predicted by several well motivated models to yield Standard Model particles through self-annihilation that can potentially be detected by astrophysi…
SkyFACT: High-dimensional modeling of gamma-ray emission with adaptive templates and penalized likelihoods
Emma Storm, Christoph Weniger, Francesca Calore
We present SkyFACT (Sky Factorization with Adaptive Constrained Templates), a new approach for studying, modeling and decomposing diffuse gamma-ray emission. Like most previous ana…
