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…

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…

On the Gamma-ray Efficiency of Superluminous Supernovae: Potential Detections and Population-Level Constraints

Milena Crnogorčević, Tim Linden, Ariel Goobar +1

Superluminous supernovae (SLSNe) are among the most energetic stellar explosions, yet their central power source remains uncertain. Models invoking magnetar spin-down or circumstel…

Dark matter silences Cepheids in the Galactic Center

Djuna Croon, Tim Linden, Jeremy Sakstein

Upcoming near-infrared facilities (e.g. JWST/NIRCam, ELT/MICADO) will dramatically increase the detectability of galactic center Cepheids despite extreme extinction at optical wave…

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…
