Addressing the Impact of Solar Modulation Systematic Uncertainties on Cosmic-Ray Propagation Models
Isabelle John, Alessandro Cuoco, Mattia Di Mauro
We perform a comprehensive analysis of cosmic-ray propagation using the time-dependent AMS-02 flux measurements covering a full solar cycle, with particular emphasis on the role of…
INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, and Vectors
Thong T. Q. Nguyen, Pedro De la Torre Luque, Isabelle John +3
The decay of light bosonic dark matter particles can produce a bright electron/positron () flux that can be strongly constrained by local Voyager observations of the direct…
First Observations of Solar Halo Gamma Rays Over a Full Solar Cycle
Tim Linden, Jung-Tsung Li, Bei Zhou +4
We analyze 15 years of Fermi-LAT data and produce a detailed model of the Sun's inverse-Compton scattering emission (solar halo), which is powered by interactions between ambient c…
Every Nearby Energetic Pulsar Is Surrounded by a Region of Inhibited Diffusion
Isabelle John, Tim Linden
The H.E.S.S. telescope has recently detected the total electron-plus-positron () flux up to 40 TeV, finding it to be a featureless and steeply-falling power-law above 1 TeV…
Strong Constraints on Dark Photon and Scalar Dark Matter Decay from INTEGRAL and AMS-02 data
Thong T. Q. Nguyen, Isabelle John, Tim Linden +1
We investigate the decay of bosonic dark matter with masses between 1 MeV and 2 TeV into Standard Model final states. We specifically focus on dark photons that kinetically mix wit…
Dark Branches of Immortal Stars at the Galactic Center
Isabelle John, Rebecca K. Leane, Tim Linden
We show that stars in the inner parsec of the Milky Way can be significantly affected by dark matter annihilation, producing population-level effects that are visible in a Hertzspr…
Dark Matter Scattering Constraints from Observations of Stars Surrounding Sgr A*
Isabelle John, Rebecca K. Leane, Tim Linden
High resolution infrared data has revealed several young stars in close proximity to Sgr A*. These stars may encounter extremely high dark matter densities. We examine scenarios wh…
Accurate Inverse-Compton Models Strongly Enhance Leptophilic Dark Matter Signals
Isabelle John, Tim Linden
The annihilation of TeV-scale leptophilic dark matter into electron-positron pairs (hereafter ) will produce a sharp cutoff in the local cosmic-ray spectrum at an…
Pulsars Do Not Produce Sharp Features in the Cosmic-Ray Electron and Positron Spectra
Isabelle John, Tim Linden
Pulsars are considered to be the leading explanation for the excess in cosmic-ray positrons detected by PAMELA and AMS-02. A notable feature of standard pulsar models is the sharp…
Cosmic-Ray Positrons Strongly Constrain Leptophilic Dark Matter
Isabelle John, Tim Linden
Cosmic-ray positrons have long been considered a powerful probe of dark matter annihilation. In particular, myriad studies of the unexpected rise in the positron fraction have deba…
Recommendations of the LHC Dark Matter Working Group: Comparing LHC searches for heavy mediators of dark matter production in visible and invisible decay channels
Andreas Albert, Mihailo Backovic, Antonio Boveia +27
Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, the LHC would produce dark matter through these mediators, leading to…
