Gravitational waves from first-order phase transitions: Ultra-supercooled transitions and the fate of relativistic shocks
Ryusuke Jinno, Hyeonseok Seong, Masahiro Takimoto +1
We study the gravitational wave (GW) production in extremely strong first order phase transitions where the latent heat density dominates the plasma energy density, . I…
Gravitational waves from bubble collisions: analytic derivation
Ryusuke Jinno, Masahiro Takimoto
We consider gravitational wave production by bubble collisions during a cosmological first-order phase transition. In the literature, such spectra have been estimated by simulating…
Suppressed Non-Gaussianity in the Curvaton Model
Kyohei Mukaida, Kazunori Nakayama, Masahiro Takimoto
We show that the local type non-Gaussianity in a class of curvaton models is suppressed, i.e. the non-linearity parameters f_{NL} and those related with higher order statistics can…
