Cosmic censorship of trans-Planckian field ranges in gravitational collapse
Published 2020-09-01“…In this paper, we consider an inverse problem: what kind of field ranges arise during the gravitational collapse of a classical field? Despite the fact that collapse has been studied for almost a hundred years, most of the discussion is phrased in terms of fluid stress tensors, and not fields. …”

Planetesimal Initial Mass Functions Following Diffusion-regulated Gravitational Collapse
Published 2023-01-01“…We compare our prediction to high-resolution numerical simulations of the streaming instability and planetesimal formation via gravitational collapse. We find that our IMF prediction agrees with numerical results and is consistent with both the paradigm that planetesimals are born big and the power-law description commonly found in simulations.…”
