An Anomaly in the Angular Distribution of Quasar Magnitudes: Evidence for a Bubble Universe with a Mass ~10^21 M\odot
Anomaly Angular Distribution Quasar Magnitudes Bubble Universe Mass
2012/2/21
Quasars provide our farthest-reaching view of the Universe. The Sloan Survey now contains over 100,000 quasar candidates. A careful look at the angular distribution of quasar magnitudes shows a surpri...
We explore the ultimate fate of the Universe by using a divergence-free parametrization for dark energy $w(z)=w_0+w_a({\ln (2+z)\over 1+z}-\ln2)$. Unlike the CPL parametrization, this parametrization ...

We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...

There is a phenomenon that the inverse image of a given celestial object could in principle be seen in negative directions in a closed universe which there is no horizon problem, but it is difficult t...

From Karlsson’s formula and the polar effect, we realize that the half periodic parameter of redshift is 0.206, in theory, we finally explain why the great wall is at redshift Z=0.079 in redshift spac...

2011/10/20
To perform imaging observation of optically red objects such as high redshift quasars and brown dwarfs, the Center for the Exploration of the Origin of the Universe (CEOU) recently developed an optica...
Bulk Viscous LRS Biachi-I Universe with variable $G$ and decaying $ニ$
LRS Bianchi type I Universe, Bulk viscosity, Variable G and
2011/8/26
The present study deals with spatially homogeneous and totally anisotropic locally rotationally symmetric (LRS) Bianchi type I cosmological model with variable G and in presence of imperfect fluid. ...
It has recently been argued by Copeland et al. that in eleven dimensions two orbifold planes can collide and bounce in a regular way, even when the bulk metric is perturbed away from Milne spacetime t...
Genesis of the dusty Universe: modeling submillimetre source counts
galaxies: evolution – galaxies: general – galaxies: starburst – infrared:galaxies – submillimetre: galaxies
2011/10/13
We model the evolution of IR galaxies using a phenomenological approach to match the observed source counts at different IR wavelengths. We introduce a new algorithm for reproducing source counts base...
The Lyman-alpha forest in a blazar-heated Universe
cosmology: theory { methods: numerical | intergalactic medium
2011/10/12
It has been realised only recently that TeV emission from blazars can significantly heat the intergalactic medium (IGM) by pair-producing high-energy electrons and positrons, which in turn excite vigo...
The Chemistry of the Early Universe

The chemistry of the early Universe is a fascinating field of study. Even in the absence of any elements heavier than lithium, a surprising degree of chemical complexity proves to be possible, giving ...
Who discovered the expanding universe? Was it Hubble, or Lemaitre, or was it just the end result of a long series of investigations? In this article we summarise the main steps and contributions that ...
Abstract: The Hubble law, determined from the distance modulii and redshifts of galaxies, for the past 80 years, has been used as strong evidence for an expanding universe. This claim is reviewed in l...
