Description:

Studying astrophysical processes in the lab becomes increasingly possible and exciting, complementing numerical simulations. In this colloquium, I will describe two example experimental efforts that I am closely involved in. The first one is about mechanisms of rapid angular momentum transport required to explain the observed fast accretion such as star formation and powering quasars. By carefully isolating effects due to artificial boundaries that are unavoidable in terrestrial experiments, key astrophysical questions regarding hydrodynamic and magnetohydrodynamic stabilities can be uniquely studied in the laboratory. Future prospects of the growing field of laboratory plasma astrophysics will be discussed.
