SUMMARY:A Predictive Theory of Star Formation and Turbulence Driving A
cross Cosmic Time\, Astronomy Colloquium\, Blakesley Burkhart\, Rutger
s/Flatiron Institute
DESCRIPTION:The interstellar medium (ISM) is a multiphase environment
where magnetohydrodynamic (MHD) turbulence affects many key processes
that govern the evolution of galactic disks include star formation.
\nIn this talk\, I shall present an overview of new analytic models
connecting turbulence\, star formation\, feedback\, and disk instabili
ty. I will show that the turbulence in discs can be powered primarily
by star formation feedback\, radial transport\, or a combination of th
e two. From scales of giant molecular clouds (GMCs)\, I will demonstra
te how the star formation efficiency can be analytically calculated fr
om our understanding of how turbulence\, gravity\, and stellar feedbac
k induce density fluctuations in the ISM via a probability distributio
n function analysis. This analytic calculation predicts star formation
rates and star formation efficiency from pc size scales (GMCs) to kpc
size scales in galaxies and provides predictions for upcoming high-z
JWST observations.
