The Evolution of Substructure during Star Cluster Assembly

open access: yesThe Astrophysical Journal
Star cluster formation and assembly occur inside filamentary and turbulent molecular clouds, which imprint both spatial and kinematic substructure on the young cluster.

Magnetically Arrested Circumbinary Accretion Flows

open access: yesThe Astrophysical Journal Letters
Binary systems with comparable masses and a surrounding accretion disk can accrete gas through spiral accretion streams penetrating the central cavity formed by tidal interactions.

Dynamical Inference from Polarized Light Curves of Sagittarius A*

open access: yesThe Astrophysical Journal
Polarimetric light curves of Sagittarius A* (Sgr A*) sometimes exhibit loops in the Stokes Q and U plane over time, often interpreted as orbiting hotspot motion. In this work, we apply the differential geometry of planar curves to develop a new technique
