Hemispherical power asymmetry: parameter estimation from CMB WMAP5 data
Bartosz Lew
We reexamine the evidence of the hemispherical power asymmetry, detected in the CMB WMAP data using a new method. At first, we analyze the hemispherical variance ratios and compare…
Real space tests of the statistical isotropy and Gaussianity of the WMAP CMB data
Bartosz Lew
ABRIDGED: We introduce and analyze a method for testing statistical isotropy and Gaussianity and apply it to the WMAP CMB foreground reduced, temperature maps, and cross-channel di…
A test of the Poincare dodecahedral space topology hypothesis with the WMAP CMB data
B. S. Lew, B. F. Roukema
It has been suggested by Roukema and coworkers (hereafter R04) that the topology of the Universe as probed by the ``matched circles'' method using the first year release of the WMA…
A new approach for constraining the Hubble constant from proper motions of radio jets
Bartosz Lew, Boudewijn F. Roukema, Silke Britzen +1
Withdrawn due to a mistake in jets' Doppler factor modeling. An updated version will appear after revisiting this work.
A Hint of Poincaré Dodecahedral Topology in the WMAP First Year Sky Map
Boudewijn F. Roukema, Bartosz Lew, Magdalena Cechowska +2
Luminet et al. (2003) suggested that WMAP data are better matched by a Poincaré dodecahedral FLRW model of global geometry, rather than by an infinite flat model. The analysis by C…
