Self-Generated Cosmic-Ray Turbulence Can Explain the Morphology of TeV Halos
Payel Mukhopadhyay, Tim Linden
Observations have shown that spatially extended "TeV halos" are a common (and potentially generic) feature surrounding young and middle-aged pulsars. However, their morphology is n…
Dark Matter Microhalos in the Solar Neighborhood: Pulsar Timing Signatures of Early Matter Domination
M. Sten Delos, Tim Linden
Pulsar timing provides a sensitive probe of small-scale structure. Gravitational perturbations arising from an inhomogeneous environment could manifest as detectable perturbations…
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…
Response to Comment on "Dark Matter Annihilation Can Produce a Detectable Antihelium Flux through Decays"
Martin Wolfgang Winkler, Tim Linden
In a recent paper we showed that the decay of intermediate baryons can dramatically enhance the antihelium flux from dark matter annihilation. Our antihelium predictions…
Gamma-Rays from Star Forming Activity Appear to Outshine Misaligned Active Galactic Nuclei
Carlos Blanco, Tim Linden
The total extragalactic -ray flux provides a powerful probe into the origin and evolution of the highest energy processes in our universe. An important component of this emissio…
First Analysis of Jupiter in Gamma Rays and a New Search for Dark Matter
Rebecca K. Leane, Tim Linden
We present the first dedicated -ray analysis of Jupiter, using 12 years of data from the Fermi Telescope. We find no robust evidence of -ray emission, and set upper limits of…
Evidence of TeV Halos Around Millisecond Pulsars
Dan Hooper, Tim Linden
Using data from the HAWC gamma-ray Telescope, we have studied a sample of 37 millisecond pulsars (MSPs), selected for their spindown power and proximity. From among these MSP, we h…
Celestial-Body Focused Dark Matter Annihilation Throughout the Galaxy
Rebecca K. Leane, Tim Linden, Payel Mukhopadhyay +1
Indirect detection experiments typically measure the flux of annihilating dark matter (DM) particles propagating freely through galactic halos. We consider a new scenario where cel…
The Highest Energy HAWC Sources are Likely Leptonic and Powered by Pulsars
Takahiro Sudoh, Tim Linden, Dan Hooper
The HAWC Collaboration has observed gamma rays at energies above 56 TeV from a collection of nine sources. It has been suggested that this emission could be hadronic in nature, req…
