The XMM-Newton Serendipitous Survey V. Optical identification of the XMM-Newton Medium sensitivity Survey (XMS)
X. Barcons, F. J. Carrera, M. T. Ceballos +53
We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comp…
Time delay by primordial density fluctuations: its biasing effect on the observed mean curvature of the Universe
Richard Lieu, Jonathan P. D. Mittaz
In this paper we specifically studied one aspect of foreground primordial matter density perturbations: the relative gravitational time delay between a pair of light paths convergi…
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 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…
On the absence of gravitational lensing of the cosmic microwave background
Richard Lieu, Jonathan P. D. Mittaz
The magnification of distant sources by mass clumps at lower () redshifts is calculated analytically. The clumps are initially assumed to be galaxy group isothermal spher…
