000002589 520__ $$aInfrared and radio observations reveal large reservoirs of molecular gas in optical filaments seen in cooling flows in clusters of galaxies. Recent Spitzer observations show that molecular hydrogen emission occurs over a broad range of temperatures, ranging from roughly 300 K to 2000 K. Central questions involve the history of the filaments, their total mass, and the energy sources responsible for the molecular hydrogen and low-ionization emission. Here we present numerical simulations of the effects of cosmic rays or thermalized heating upon otherwise well shielded molecular gas. We show diagnostic excitation and emission diagrams and discuss implications for the nature of the emission.
