Opacity Broadening of ${}^{13}$CO Linewidths and its Effect on the Variance-Sonic Mach Number Relation

Caio Correia, Blakesley Burkhart, Alex Lazarian +5

We study how the estimation of the sonic Mach number ($M_s$) from ${}^{13}$CO linewidths relates to the actual 3D sonic Mach number. For this purpose we analyze MHD simulations which…
