Observational Constraints on Interacting Model of New Agegraphic Dark Energy and Alleviation of Cosmic Age Problem
Observational Constraints on Interacting Model Agegraphic Dark Energy
2010/12/27
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 $\Lambda$CDM model and the holographic dark energy model are not exception. I...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Observational constraints Chaplygin cosmology braneworld scenario
2010/12/27
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss-Bonnet term in the ...

Observational Constraints on Exponential Gravity
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/28
We study the observational constraints on the exponential gravity model of f(R)=-beta*Rs(1-e^(-R/Rs)). We use the latest observational data including Supernova Cosmology Project (SCP) Union2 compilati...
Observational constraints on Galileon cosmology
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc) High Energy Physics - Phenomenology (hep-ph) High Energy Physics - Theory (hep-th)
2010/12/23
We study the cosmology of a covariant Galileon field with five covariant Lagrangians and confront this theory with the most recent cosmological probes: the type Ia supernovae data (Constitution and Un...
Observational constraints on the global atmospheric budget of ethanol
Observational constraints the global atmospheric budget of ethanol
2010/8/13
Energy security and climate change concerns have led to the promotion of biomass-derived ethanol, an oxygenated volatile organic compound (OVOC), as a substitute for fossil fuels. Although ethanol is ...
Observational Constraints on the Completeness of Space near Astrophysical Objects
Space near Astrophysical Objects double pulsar
2010/3/18
We consider the observational effects of a deficit angle, w, in the topology of the solar system and in the 'double pulsar' system PSR J0737-3039A/B. Using observations of the perihelion precession of...
Observational Constraints on Transverse Gravity: a Generalization of Unimodular Gravity
Transverse Gravity Unimodular Gravity
2010/3/19
We explore the hypothesis that the set of symmetries enjoyed by the theory that describes gravity is not the full group of diffeomorphisms Diff(M), as in General Relativity, but a maximal subgroup of ...

STRUCTURE FORMATION COSMIC RAYS：IDENTIFYING OBSERVATIONAL CONSTRAINTS
cosmic rays-Gamma rays theory-Gamma rays observations-Nuclear reactions, nucleosynthesis, abundances
2009/2/25
Shocks that arise from baryonic in-fall and merger events during
the structure formation are believed to be a source of cosmic rays. These "struc-
ture formation cosmic rays" (SFCRs) would essential...
