Your "given that" does not make logical sense. WebIn this work, our aim is to obtain scaling relations for the turbulence parameters l, u and in terms of other quantities like gas density, sound speed, and supernova rate density. The latter parameters are often readily computed from observations or models, so such relations can provide a missing link.
