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…
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…
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 Enigmatic Galactic Center Excess: Spurious Point Sources and Signal Mismodeling
Rebecca K. Leane, Tracy R. Slatyer
The Galactic Center GeV excess (GCE) has garnered great interest as a possible signal of either dark matter annihilation or some novel astrophysical phenomenon, such as a new popul…
Spurious Point Source Signals in the Galactic Center Excess
Rebecca K. Leane, Tracy R. Slatyer
We re-examine evidence that the Galactic Center Excess (GCE) originates primarily from point sources (PSs). We show that in our region of interest, non-Poissonian template fitting…
Dark Matter Strikes Back at the Galactic Center
Rebecca K. Leane, Tracy R. Slatyer
Statistical evidence has previously suggested that the Galactic Center GeV Excess (GCE) originates largely from point sources, and not from annihilating dark matter. We examine the…
The Sun at GeV--TeV Energies: A New Laboratory for Astroparticle Physics
M. U. Nisa, J. F. Beacom, S. Y. BenZvi +5
The Sun is an excellent laboratory for astroparticle physics but remains poorly understood at GeV--TeV energies. Despite the immense relevance for both cosmic-ray propagation and d…
First HAWC Observations of the Sun Constrain Steady TeV Gamma-Ray Emission
A. Albert, R. Alfaro, C. Alvarez +92
Steady gamma-ray emission up to at least 200 GeV has been detected from the solar disk in the Fermi-LAT data, with the brightest, hardest emission occurring during solar minimum. T…
Powerful Solar Signatures of Long-Lived Dark Mediators
Rebecca K. Leane, Kenny C. Y. Ng, John F. Beacom
Dark matter capture and annihilation in the Sun can produce detectable high-energy neutrinos, providing a probe of the dark matter-proton scattering cross section. We consider the…
