Prospects of determination of reheating temperature after inflation by DECIGO
Sachiko Kuroyanagi, Kazunori Nakayama, Jun'ichi Yokoyama
If the tensor-to-scalar ratio of cosmological perturbations takes a large value , which may be inferred by recent BICEP2 result, we can hope to determine thermal his…
Gravitational waves as a probe of dark matter mini-spikes
Kazunari Eda, Yousuke Itoh, Sachiko Kuroyanagi +1
Recent studies show that an intermediate mass black hole (IMBH) may develop a dark matter (DM) mini-halo according to some BH formation scenarios. We consider a binary system compo…
Blue-tilted Tensor Spectrum and Thermal History of the Universe
Sachiko Kuroyanagi, Tomo Takahashi, Shuichiro Yokoyama
We investigate constraints on the spectral index of primordial gravitational waves (GWs), paying particular attention to a blue-tilted spectrum. Such constraints can be used to tes…
Implications of the B-mode Polarization Measurement for Direct Detection of Inflationary Gravitational Waves
Sachiko Kuroyanagi, Shinji Tsujikawa, Takeshi Chiba +1
The prospects for direct measurements of inflationary gravitational waves by next generation interferometric detectors inferred from the possible detection of B-mode polarization o…
