Extragalactic H3O+: Some Consequences
arXiv:0801.1372 · doi:10.1051/eas:0831022
Abstract
We discuss some implications of our recent detection of extragalactic H3O+: the location of the gas in M82, the origin of energetic radiation in M82, and the possible feedback effects of star formation on the cosmic ray flux in galaxies.
