Induced gravitational waves as a cosmological probe of the sound speed during the QCD phase transition
Katsuya T. Abe, Yuichiro Tada, Ikumi Ueda
The standard model of particle physics is known to be intriguingly successful. However their rich phenomena represented by the phase transitions (PTs) have not been completely unde…

The 21-cm signals from ultracompact minihalos as a probe of primordial small-scale fluctuations
Kunihiko Furugori, Katsuya Abe, Toshiyuki Tanaka +3
Ultracompact minihalos~(UCMHs) can form after the epoch of matter-radiation equality, if the density fluctuations of dark matter have significantly large amplitude on small scales.…
