Breaking the dark force [PDF]

open access: yesJournal of High Energy Physics, 2009
Recently Arkani-Hamed, Finkbeiner, Slatyer and Weiner proposed a unified explanation to the set of experimental and observational anomalies with possible connections to Dark Matter (DM). A central role is played by GeV scale "dark" gauge bosons exchanged by the weak scale DM.

Breaking the ice: Identifying hydraulically-forced crevassing [PDF]

open access: yesGeophysical Research Letters, 2020
Hydraulically-forced crevassing is thought to reduce the stability of ice shelves and ice sheets, affecting structural integrity and providing pathways for surface meltwater to the bed. It can cause ice shelves to collapse and ice sheets to accelerate into the ocean.
