The quest for cosmic ray protons in galaxy clusters
Christoph Pfrommer, Torsten A. Ensslin
There have been many speculations about the presence of cosmic ray protons (CRps) in galaxy clusters over the past two decades. However, no direct evidence such as the characterist…
Unveiling the composition of radio plasma bubbles in galaxy clusters with the Sunyaev-Zel'dovich effect
Christoph Pfrommer, Torsten A. Ensslin, Craig L. Sarazin
The Chandra X-ray Observatory is finding a large number of cavities in the X-ray emitting intra-cluster medium which often coincide with the lobes of the central radio galaxy. We p…
Statistical distribution of gravitational-lensing excursion angles: Winding ways to us from the deep universe
Takashi Hamana, Matthias Bartelmann, Naoki Yoshida +1
We investigate statistical distributions of differences in gravitational-lensing deflections between two light rays, the so-called lensing excursion angles. A probability distribut…
Detecting Sunyaev-Zel'dovich clusters with PLANCK: II. Foreground components and optimised filtering schemes
Bjoern Malte Schaefer, Christoph Pfrommer, Reinhard Hell +1
The PLANCK mission is the most sensitive all-sky CMB experiment currently planned. The High Frequency Instrument (HFI) will be especially suited for observing clusters of galaxies…
Detecting Sunyaev-Zel'dovich clusters with PLANCK: I. Construction of all-sky thermal and kinetic SZ-maps
Bjoern Malte Schaefer, Christoph Pfrommer, Matthias Bartelmann +2
All-sky thermal and kinetic Sunyaev-Zel'dovich (SZ) maps are presented for assessing how well the PLANCK-mission can find and characterise clusters of galaxies, especially in the p…
Estimating galaxy cluster magnetic fields by the classical and hadronic minimum energy criterion
Christoph Pfrommer, Torsten A. Ensslin
We wish to estimate magnetic field strengths of radio emitting galaxy clusters by minimising the non-thermal energy density contained in cosmic ray electrons (CRe), protons (CRp),…
