Topological Lensing: Is the Matter Both Here and There?
B. F. Roukema, A. Marecki, S. Bajtlik +1
If the Universe satisfies a perturbed Friedmann-Lema\^ıtre model, then the bright matter (e.g. radio-loud active galactic nuclei, RLAGNs) may be topologically lensed by global geom…
Where the Very Bright Matter is a Standard Ruler
B. F. Roukema, G. A. Mamon, S. Bajtlik
Where's the matter? The answer seems to be: ``distributed according to a power spectrum with at least one feature (local maximum) near 120-130h^-1Mpc''. Analyses of the Iovino, Clo…
The Milky Way as the Ultimate Extragalactic Source
Boudewijn F. Roukema
The GAIA satellite will observe the Galaxy and its closest satellites in great detail. This should allow (i) dating past events of dwarf galaxies merging or interacting with the Ga…
Clusters of Galaxies as Standard Candles for Global Observational Cosmology
B. F. Roukema
As the largest gravitationally collapsed objects, and as objects with a relatively low space density, clusters of galaxies offer one of the best sets of standard candles for trying…
