Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun
Thong T. Q. Nguyen, Tim Linden, Pierluca Carenza +1
The Sun can efficiently capture leptophilic dark matter that scatters with free electrons. If this dark matter subsequently annihilates into leptonic states, it can produce a detec…
Phase spirals across galactic disks I: Exploring dynamical influences on winding
Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +4
The vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influen…
The phase spiral's origin and evolution: indications from its varying properties across the Milky Way disk
Axel Widmark, Kiyan Tavangar, Josh Kalish +2
The phase spiral is a perturbation to the vertical phase-space distribution of stars in the Milky Way disk. We study the phase spiral's properties and how they vary with spatial po…
Using simulation based inference on tidally perturbed dwarf galaxies: the dynamics of NGC205
Axel Widmark, Kathryn V. Johnston
We develop a novel approach to performing precision inference on tidally perturbed dwarf galaxies. We use a Bayesian inference framework of implicit likelihood inference, previousl…
