| 研究実績の概要 |
Among the milestones of the project is the development of GW-galaxy cross-correlation frameworks both with resolved GW sources and GW backgrounds in the context of the next generation of GW experiments and upcoming galaxy surveys, such as PFS or Euclid. I have released a public lightweight code for performing GW-galaxy correlation forecasting analyses. An additional achievement has been the study of population modeling of black hole-neutron star mergers, especially in connection with addressing the question of whether the observed black holes can be of primordial origin.Another important milestone of the project concerns the modeling of stochastic GW backgrounds. Particularly, I have contributed to the development of methodologies to model the anisotropies of GW backgrounds originating from primordial black hole scenarios and performed a forecasting analysis to address their detectability with the next generation of GW experiments and the prospects of distinguishing such a background from the one emitted by astrophysical binaries. An additional aspect of GW backgrounds is the careful modeling of signals from the early universe, which is important in order to correctly interpret any possible detection in the future. For this, I have led a study clarifying an open question regarding the production of induced gravitational waves during inflation.
