ROSAT observations of the soft X-ray background and of the cluster soft excess emission in the Hercules supercluster
Max Bonamente, Richard Lieu, Jelle Kaastra
Recent observations with the XMM-Newton satellite confirmed the existence of the soft excess phenomenon in galaxy clusters, earlier discovered in several EUVE, ROSAT and BeppoSAX o…
The Sunyaev-Zel'dovich effect in a sample of 31 clusters - a comparison between the X-ray predicted and WMAP observed CMB temperature decrement
Richard Lieu, Jonathan P. D. Mittaz, Shuang-Nan Zhang
The WMAP Q, V, and W band radial profiles of temperature deviation of the cosmic microwave background (CMB) were constructed for a sample of 31 randomly selected nearby clusters of…
Thermal and non-thermal nature of the soft excess emission from Sersic 159-03 observed with XMM-Newton
M. Bonamente, R. Lieu, J. P. D. Mittaz +2
Several nearby clusters exhibit an excess of soft X-ray radiation which cannot be attributed to the hot virialized intra-cluster medium. There is no consensus to date on the origin…
The effect of long range gravitational perturbations on the first acoustic peak of the cosmic microwave background
Richard Lieu
In the standard cosmological model, the temperature anisotropy of the cosmic microwave background is interpreted as variation in the gravitational potential at the point of emissio…
The Cluster Soft Excess: new faces of an old enigma
Richard Lieu, Jonathan Mittaz
Until the advent of XMM-Newton, the cluster soft excess (CSE) was the subject of some controversy due to both data analysis issues and uncertainties with the soft excess emission m…
