Practicum Title:

Mapping magnetic fields in star-forming regions with deep learning

Summary of Research

Many astrophysical processes span wide ranges in spatial and temporal scales, and physical experiments aimed at testing our current understanding of these processes are often infeasible. I use numerical simulations to help bridge theory and observations, with an emphasis on topics relating to star formation, such as, "Why is star formation so inefficient?" and "What mechanisms may result in the formation of bound stellar systems?" Currently, I am exploring how protostellar disks (which form around young protostars as a consequence of the conservation of angular momentum during the gravitational collapse process) may become gravitationally unstable, and subsequently fragment to form tightly-bound companion stars.
