Bio

Andrea Antoni joined the Center for Computational Astrophysics (CCA) as a Flatiron Research Fellow in 2024. Her work focuses on the late and final stages of massive stellar evolution with an emphasis on hydrogen-rich progenitors of stellar-mass black holes. She uses a combination of magneto-hydrodynamical and radiation-hydrodynamical simulations to study the dynamics of implosion and explosion of these stars and to model the resulting observational signatures of these events. Prior to joining CCA, Andrea earned her Ph.D. in astrophysics from the University of California, Berkeley.
