Fractional Action Cosmology: Some Dark Energy Models in Emergent, Logamediate and Intermediate Scenarios of the Universe
Fractional Action Cosmology Dark Energy Model Emergent Logamediate Intermediate Scenarios of the Universe
2011/8/2
Abstract: In the framework of Fractional Action Cosmology, we have reconstructed the scalar potentials and scalar fields, namely, quintessence, phantom, tachyon, k-essence, DBI-essence, Hessence, dila...
Modeling high-energy cosmic ray induced terrestrial muon flux: A lookup table
Modeling high-energy cosmic ray induced terrestrial muon flux
2010/12/27
On geological timescales, the Earth is likely to be exposed to an increased flux of high energy cosmic rays (HECRs) from astrophysical sources such as nearby supernovae, gamma ray bursts or by galacti...

Energy conditions modified Gauss-Bonnet gravity
2010/12/27
In considering alternative higher-order gravity theories, one is liable to be motivated in pursuing models consistent and inspired by several candidates of a fundamental theory of quantum gravity. In...
Cosmological observations on the largest scales exhibit a solid record of unexpected anomalies and alignments, apparently pointing towards a large scale violation of statistical isotropy. These inclu...

Observational Constraints on Interacting Model of New Agegraphic Dark Energy and Alleviation of Cosmic Age Problem
Interacting Model New Agegraphic Dark Energy Alleviation of Cosmic Age Problem
2010/12/21
Many dark energy models fail to pass the cosmic age test via the old quasar APM 08279+5255 at
redshift z = 3.91, even the CDM model and the holographic dark energy model are not exception.In this pa...
String Cosmology in LRS Bianchi Type-II Dusty Universe with Time Decaying Vacuum Energy Density $\Lambda$
LRS Bianchi type II models Nambu String Massive string
2010/12/21
A model of a cloud formed by massive strings is used as a source of LRS Bianchi type II with time decaying vacuum energy density . To construct string cosmological models we have used the energy-mome...
Notes on Ghost Dark Energy
Notes Ghost Dark Energy
2010/12/21
We study a phenomenological dark energy model which is rooted in the Veneziano ghost of QCD. In this dark energy model, the energy density of dark energy is proportional to Hubble parameter and the pr...
Dark Energy And Life's Ultimate Future
Cosmological Constant Quintessence Far Future Intelligence
2011/9/8
The discovery of the present accelerated expansion of space changed everything regarding cosmology and life's ultimate prospects. Both the optimistic scenarios of an ever (but decelerated) expanding u...
Generalized Brans-Dicke cosmology in the presence of matter and dark energy
Brans-Dicke cosmology time-dependent expansion inflation dark energy
2010/3/17
We study the Generalized Brans-Dicke cosmology in the presence of matter and dark energy. Of particular interest for a constant Brans-Dicke parameter, the de Sitter space has also been investigated.
A Faraway Quasar in the Direction of the Highest Energy Auger Event
cosmic rays acceleration of particles radio galaxies particle physics
2010/3/15
The highest energy cosmic ray event reported by the Auger Observatory has an energy of 148 EeV. It does not correlate with any nearby (z$<$0.024) object capable of originating such a high energy event...
The entropy and mean separation between energy levels of black hole
mean separation energy levels black hole
2010/3/17
According to the widely accepted statistical interpretation of black hole entropy the mean separation between energy levels of black hole should be exponentially small. But this sharply disagrees with...
