Where are the Cascades from Blazar Jets? An Emerging Tension in the $\gamma$-ray sky

Autor: Blanco, Carlos, Ghosh, Oindrila, Jacobsen, Sunniva, Linden, Tim

Blazars are among the most powerful accelerators and are expected to produce a bright TeV $\gamma$-ray flux. However, TeV $\gamma$-rays are attenuated by interactions with intergalactic radiation before reaching Earth. These interactions produce casc

Constraining Axion-Like Particles with HAWC Observations of TeV Blazars

Autor: Jacobsen, Sunniva, Linden, Tim, Freese, Katherine

Axion-like particles (ALPs) are a broad class of pseudo-scalar bosons that generically arise from broken symmetries in extensions of the standard model. In many scenarios, ALPs can mix with photons in regions with high magnetic fields. Photons from d

Inelastic dark matter scattering off Thallium cannot save DAMA

Autor: Jacobsen, Sunniva, Freese, Katherine, Kelso, Chris, Sandick, Pearl, Stengel, Patrick

We study the compatibility of the observed DAMA modulation signal with inelastic scattering of dark matter (DM) off of the $0.1\%$ Thallium (Tl) dopant in DAMA. In this work we test whether there exist regions of parameter space where the Tl interpre

DAMA annual modulation is not due to electron recoils from Plasma/Mirror Dark Matter with Kinetic Mixing

Autor: Adams, Douglas Q., Jacobsen, Sunniva, Kelso, Chris

If dark matter is composed of new fundamental particles, Earth's orbital motion around the Sun may induce an annual modulation in the rate at which these particles interact in a terrestrial detector. The DAMA collaboration has identified at a 12$\sig
