abstract
On first look, submillimeter astronomy and high energy astrophysics have little in common - micro to milli electron Volt energies there and Mega-,Giga-, and now even TeraeV here. Nevertheless, as I'll briefly review, high energy processes have a profound relation to the physics and chemistry of the interstellar medium. Recently found correlations between diffuse TeV gamma ray emission and dense interstellar cloud material, in particular in the Galactic center region and around supernova remnants indicate that large concentrations of hadrons are the sources of the TeV emission. I'll try to illustrate these interesting connection with a number of recently investigated examples.
