Shape and geometry of galaxy clusters and the SZ effect
L. Grenacher, R. Piffaretti, D. Puy +2
We discuss the influence of the finite extension and the geometry of clusters of galaxies, as well as of the polytropic temperature profile, on the determination of the Hubble cons…
H2 molecules and cold clouds in cooling flow clusters
L. Grenacher, Ph. Jetzer, D. Puy
We investigated the cooling mechanism due to H2 and HD molecules in order to determine the minimum temperature achievable by cold H2-HD clouds in cooling flow clusters.
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…
