However, the comparison of masses deduced from the continuum SIMBA 1.2 mm emission and virial masses (understood to trace the entire potential of the clouds) in a sample of giant molecular clouds in the Small Magellanic Cloud (SMC) by previous studies found a discrepancy between these two quantities that requires explanation. ...

... I will discuss how observations of synchrotron intensity fluctuations can be used to probe the sonic and Alfvenic Mach numbers of interstellar turbulence, based on mock observations performed on simulations of magneto-hydrodynamic turbulence. I will also discuss the potential for novel polarisation analysis techniques to uniquely determine the sonic and Alfvenic Mach numbers of observed turbulence, and to assist in qualitative understanding of Galactic magneto-ionic turbulence. ...

... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...
