Molecular clouds in cooling flow cluster of galaxies
L. Grenacher, Ph. Jetzer, D. Puy
In many clusters of galaxies there is evidence for cooling flow in the central regions. A possibility is that a fraction of the gas forms cold molecular clouds. We investigate the…

Cold clouds in cooling flows
L. Grenacher, Ph. Jetzer, D. Puy
In many clusters of galaxies there is evidence for cooling flows which deposit large quantities of cool gas in the central regions. A fraction of this gas might accumulate as dense…
