Hubble redshift and the Heisenberg frequency uncertainty: on a coherence (or pulse) time signature in extragalactic light
Richard Lieu
In any Big Bang cosmology, the frequency of light detected from a distant source is continuously and linearly changing (usually redshifting) with elapsed observer's time ,…
On the absence of shear from perfect Einstein rings and the stability of geometry
Richard Lieu
Concordance cosmology points to a Universe of zero mean curvature, due to the inflation mechanism which occurred soon after the Big Bang, while along a relatively small number of l…
Soft and hard X-ray excess emission in Abell 3112 observed with Chandra
M. Bonamente, J. Nevalainen, R. Lieu
Chandra ACIS-S observations of the galaxy cluster A3112 feature the presence of an excess of X-ray emission above the contribution from the diffuse hot gas, which can be equally we…
CDM cosmology: how much suppression of credible evidence, and does the model really lead its competitors, using all evidence?
Richard Lieu
Astronomy can never be a hard core physics discipline, because the Universe offers no control experiment, i.e. with no independent checks it is bound to be highly ambiguous and deg…
Strong lensing time delay: a new way of measuring cosmic shear
Richard Lieu
The phenomenon of cosmic shear, or distortion of images of distant sources unaccompanied by magnification, is an effective way of probing the content and state of the foreground Un…
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…
