Millisecond Pulsars in Globular Clusters and Implications for the Galactic Center Gamma-Ray Excess

Aurelio Amerio, Dan Hooper, Tim Linden

We study the gamma-ray emission from millisecond pulsars within the Milky Way's globular cluster system in order to measure the luminosity function of this source population. We fi…

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…

Galactic Gas Models Strongly Affect the Determination of the Diffusive Halo Height

Pedro De La Torre Luque, Tim Linden

The height of the Milky Way diffusion halo, above which cosmic-rays can freely escape the galaxy, is among the most critical, yet poorly known, parameters in cosmic-ray physics. Me…

X-Ray Constraints on Dark Photon Tridents

Tim Linden, Thong T. Q. Nguyen, Tim M. P. Tait

Dark photons that are sufficiently light and/or weakly-interacting represent a compelling vision of dark matter. Dark photon decay into three photons, which we call the dark photon…

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…

Cosmic-Ray Propagation Models Elucidate the Prospects for Antinuclei Detection

Pedro De La Torre Luque, Martin Wolfgang Winkler, Tim Linden

Tentative observations of cosmic-ray antihelium by the AMS-02 collaboration have re-energized the quest to use antinuclei to search for physics beyond the standard model. However,…

Constraining the Diffusion Coefficient and Cosmic-Ray Acceleration Efficiency using Gamma-ray Emission from the Star-Forming Region RCW 38

Paarmita Pandey, Laura A. Lopez, Anna L. Rosen +3

Stellar winds from massive stars may be significant sources of cosmic rays (CRs). To investigate this connection, we report a detailed study of gamma-ray emission near the young Mi…

Indirect Searches for Dark Photon-Photon Tridents in Celestial Objects

Tim Linden, Thong T. Q. Nguyen, Tim M. P. Tait

We model and constrain the unique indirect detection signature produced by dark matter particles that annihilate through a gauge symmetry into dark photons that subsequently…

Antiproton Bounds on Dark Matter Annihilation from a Combined Analysis Using the DRAGON2 Code

Pedro De la Torre Luque, Martin Wolfgang Winkler, Tim Linden

Early studies of the AMS-02 antiproton ratio identified a possible excess over the expected astrophysical background that could be fit by the annihilation of a weakly interacting m…
