Gas clumping in galaxy clusters
D. Eckert, M. Roncarelli, S. Ettori +4
The reconstruction of galaxy cluster's gas density profiles is usually performed by assuming spherical symmetry and averaging the observed X-ray emission in circular annuli. In the…
Probing the cosmic-ray content of galaxy clusters by stacking Fermi-LAT count maps
B. Huber, C. Tchernin, D. Eckert +4
Observations in radio have shown that galaxy clusters are giant reservoirs of cosmic rays (CR). Although a gamma- ray signal from the cluster volume is expected to arise through in…
The Hot and Energetic Universe: The astrophysics of galaxy groups and clusters
S. Ettori, G. W. Pratt, J. de Plaa +28
As the nodes of the cosmic web, clusters of galaxies trace the large-scale distribution of matter in the Universe. They are thus privileged sites in which to investigate the comple…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
Sloshing cold fronts in galaxy groups and their perturbing disk galaxies: an X-ray, Optical and Radio Case Study
F. Gastaldello, L. Di Gesu, S. Ghizzardi +10
We present a combined X-ray, optical, and radio analysis of the galaxy group IC 1860 using the currently available Chandra and XMM data, literature multi-object spectroscopy data a…
The X-ray/SZ view of the virial region. II. Gas mass fraction
Dominique Eckert, Stefano Ettori, Silvano Molendi +2
Several recent studies used the hot gas fraction of galaxy clusters as a standard ruler to constrain dark energy, which provides competitive results compared to other techniques. T…
