MHD collapse simulations define an Envelope-Disk Transition Zone (ENDTRANZ) where a jump in the j-r profile occurs due to positive gravitational torques, with a corresponding jump detected in ALMA observations of L1527 IRS.
Multi-dimensional simulations show that the parameter space for shocks in non-dissipative transonic sub-Keplerian accretion flows is substantially larger than the analytic prediction, with dynamic boundary layers producing outflows.
Review chapter summarizing the importance of small-scale galactic magnetic fields and proposing SKA observation strategies.
