The temperature structure in the core of Sersic 159-03
J. de Plaa, J. S. Kaastra, M. Mendez +6
We present results from a new 120 ks XMM-Newton observation of the cluster of galaxies Sersic 159-03. In this paper we focus on the high-resolution X-ray spectra obtained with the…
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…
Proving the conservation of surface brightness during the strong and weak lensing of light by an isothermal sphere
Richard Lieu
An analytical proof of the conservation of surface brightness during the strong and weak lensing of light by a singular isothermal sphere is provided. It is shown that the movement…
The convergence fluctuation of light by clusters of galaxies - a cosmological test using the second acoustic peak of the 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…
