Redshift estimation of clusters by wavelet decomposition of their Sunyaev-Zel'dovich morphology
Bjoern Malte Schaefer, Christoph Pfrommer, Saleem Zaroubi
A method for estimating redshifts of galaxy clusters based solely on resolved Sunyaev-Zel'dovich (SZ) images is proposed. Given a high resolution SZ cluster image (with FWHM of app…
Magnetic fields and cosmic rays in cooling flows
Torsten Ensslin, Corina Vogt, Christoph Pfrommer
Cooling flows are regions where the importance of non-thermal intra-cluster medium components such as magnetic fields and cosmic rays may be strongest within a galaxy cluster. They…
Probing the Cosmic Ray Population of the Giant Elliptical Galaxy M 87 with Observed TeV Gamma-Rays
Christoph Pfrommer, Torsten A. Ensslin
We examine the cosmic ray proton (CRp) population within the giant elliptical galaxy M 87 using the TeV gamma-ray detection of the HEGRA collaboration. In our scenario, the gamma-r…
Constraining the population of cosmic ray protons in cooling flow clusters with gamma-ray and radio observations: Are radio mini-halos of hadronic origin?
Christoph Pfrommer, Torsten A. Ensslin
We wish to constrain the cosmic-ray proton (CRp) population in galaxy clusters. By hadronic interactions with the thermal gas of the intra-cluster medium (ICM), the CRp produce gam…
