Constraints on neutrino masses from WMAP5 and BBN in the lepton asymmetric universe
Maresuke Shiraishi, Kazuhide Ichikawa, Kiyotomo Ichiki +2
In this paper, we put constraints on neutrino properties such as mass and degeneracy parameters from WMAP5 data and light element abundances by using a Markov chain Mon…

Double Inflation in Supergravity and Primordial Black Holes Formation
Masahide Yamaguchi
In this talk we propose a natural double inflation model in supergravity. Chaotic inflation first takes place by virtue of the Nambu-Goldstone-like shift symmetry. During chaotic i…

Cosmological Evolution of Global Monopoles
Masahide Yamaguchi
We investigate the cosmological evolution of global monopoles in the radiation dominated (RD) and matter dominated (MD) universes by numerically solving field equations of scalar f…
