Cosmological Constraints on Radion Evolution in the Universal Extra Dimension Model
K. C. Chan, M. -C. Chu
The constraints on the radion evolution in the Universal Extra Dimension (UED) model from Cosmic Microwave Background (CMB) and Type Ia supernovae (SNe Ia) data are studied. In the…
CMB Constraint on Radion Evolution in the Brane World Scenario
K. C. Chan, M. -C. Chu
In many versions of brane model, the modulus field of extra dimensions, the radion, could have cosmological evolution, which induces variation of the Higgs vacuum expectation value…
Constraining the Variation of G by Cosmic Microwave Background Anisotropies
K. C. Chan, M. -C. Chu
We use the Cosmic Microwave Background Anisotropies (CMBA) power spectra to constrain the cosmological variation of gravitational constant G. It is found that the sensitivity of CM…
Constraints on f(R) Cosmology in the Palatini Formalism
Baojiu Li, K. C. Chan, M. -C. Chu
In this work we derive the covariant and gauge invariant perturbation equations in general theories of gravity in the Palatini formalism to linear order and calculate the co…
Studies of Air Showers above 10^18 eV with the CHICOS Array
T. W. Lynn, E. Brobeck, B. E. Carlson +10
CHICOS (California HIgh school Cosmic ray ObServatory) is presently an array of more than 140 detectors distributed over a large area (~400 km^2) of southern California, and will c…
