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…
EUV and X-ray observations of Abell 2199: a three-phase intracluster medium with a massive warm component
Richard Lieu, Max Bonamente, Jonathan P. D. Mittaz
Various independent ways of constraining key cosmological parameters yielded a consensus range of values which indicates that at the present epoch the bulk of the universe's baryon…
EUV and X-ray observation of Abell 2199: a three-phase intracluster medium with a massive warm component
Richard Lieu, Massimiliano Bonamente, Jonathan P. D. Mittaz
Various independent ways of constraining the Hubble constant and the baryonic content of the universe finally converged at a consensus range of values which indicates that at the p…
Celestial Origin of the Extended EUV Emission from the Abell 2199 and Abell 1795 Clusters of Galaxies
Richard Lieu, Jonathan P. D. Mittaz, Massimiliano Bonamente +3
Several authors (S. Bowyer, T. Berghoeffer, and E. Korpela, hereinafter abbreviated as BBK) recently announced that the luminous extended EUV radiation from the clusters Abell 1795…
