Observational Constraints on Accelerating Brane Cosmology with Exchange between the Bulk and Brane
K. Umezu, K. Ichiki, T. Kajino +3
We explore observational constraints on a cosmological brane-world scenario in which the bulk is not empty. Rather, exchange of mass-energy between the bulk and the bane is allowed…

Cosmological Constraints on Newton's Constant
K. Umezu, K. Ichiki, M. Yahiro
We present cosmological constraints on deviations of Newton's constant at large scales, analyzing latest cosmic microwave background (CMB) anisotropies and primordial abundances of…
