Strong Planck constraints on braneworld and non-commutative inflation
Gianluca Calcagni, Sachiko Kuroyanagi, Junko Ohashi +1
We place observational likelihood constraints on braneworld and non-commutative inflation for a number of inflaton potentials, using Planck, WMAP polarization and BAO data. Both br…
Planck constraints on single-field inflation
Shinji Tsujikawa, Junko Ohashi, Sachiko Kuroyanagi +1
We place observational constraints on slow-variation single-field inflationary models by carrying out the cosmological Monte Carlo simulation with the recent data of Planck combine…
A new probe of dark matter properties: gravitational waves from an intermediate mass black hole embedded in a dark matter mini-spike
Kazunari Eda, Yousuke Itoh, Sachiko Kuroyanagi +1
An intermediate mass black hole (IMBH) may have a dark matter (DM) mini-halo around it and develop a spiky structure within less than a parsec from the IMBH. When a stellar mass ob…
Early Universe Tomography with CMB and Gravitational Waves
Sachiko Kuroyanagi, Christophe Ringeval, Tomo Takahashi
We discuss how one can reconstruct the thermal history of the Universe by combining cosmic microwave background (CMB) measurements and gravitational wave (GW) direct detection expe…
