Power-law entropy corrected new holographic scalar field models of dark energy
Power-law holographic scalar field models dark energy PLECHDE model
2011/8/11
Abstract: In this work, the PLECHDE model with Granda-Oliveros infrared cutoff is studied and the evolution of dark energy density, deceleration and EoS parameters are calculated. I demonstrate that u...
Existence of Equilibrium Points and their Linear Stability in the Generalized Photogravitational Chermnykh-Like Problem with Power-law Profile
Existence of Equilibrium Points and their Linear Stability in the Generalized Photogravitational Chermnykh-Like Problem with Power-law Profile
2011/10/14
We consider the modified restricted three body problem with power-law density profile of disk, which rotates around the center of mass of the system with perturbed mean motion. Using analytical and nu...
Power-law entropy-corrected HDE and NADE in Brans-Dicke cosmology
Power-law entropy-corrected HDE Brans-Dicke cosmology
2011/10/13
Considering the power-law corrections to the black hole entropy, which appear in dealing with the entanglement of quantum fields in and out the horizon, the holographic energy density is modified acco...
Evidence for mild deviation from power-law distribution of electrons in relativistic shocks: GRB 090902B
radiation mechanisms: non-thermal - methods: analytical - methods: numerical- gamma-rays: bursts, theory - gamma-ray burst: individual: GRB090902B

Many previous studies have determined that the long lasting emission at X-ray, optical and radio wavelengths from gamma-ray bursts (GRBs), called the afterglow, is likely produced by the external forw...
In chameleon field theories a scalar field can couple to matter with gravitational strength and still evade local gravity constraints due to a combination of self-interactions and the couplings to mat...
