A galaxy dynamo by supernova-driven interstellar turbulence
Supernovae are the dominant energy source for driving turbulence within the interstellar plasma. Until recently, their effects on magnetic field amplification in disk galaxies remained a matter of speculation. By means of self-consistent simulations of supernova-driven turbulence, we find an exponential amplification of the mean magnetic field on timescales of a few hundred million years. The r...
متن کاملDDO 88: A Galaxy-Sized Hole in the Interstellar Medium
We present an H i and optical study of the gas-rich dwarf irregular galaxy DDO 88. Although DDO 88’s global optical and H i parameters are normal for its morphological type, it hosts a large (3 kpc diameter) and unusually complete ring of enhanced H i emission. The normal appearance of this galaxy in the optical and the outer regions of the H i give no hint of the presence of the striking H i r...
متن کاملThe Role of the Interstellar Medium in Galaxy Formation Simulations
There is a strong connection between the formation of a disk galaxy and the properties of the interstellar medium (ISM). Theoretical work has typically either focused on the cosmological buildup of a galaxy with a relatively crude model for the gas physics, or examined local processes in the ISM and ignored the global evolution of the galaxy itself. Here, I briefly review what has been learned ...
