primordial black holes and string axion dark matter
Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida +2
LIGO-Virgo collaboration has found black holes as heavy as through the detections of the gravitational waves emitted during their mergers. Primordial black holes…
Does the detection of primordial gravitational waves exclude low energy inflation?
Tomohiro Fujita, Ryo Namba, Yuichiro Tada
We show that a detectable tensor-to-scalar ratio on the CMB scale can be generated even during extremely low energy inflation which saturates the BBN bound $ρ_{\rm…
Consistent generation of magnetic fields in axion inflation models
Tomohiro Fujita, Ryo Namba, Yuichiro Tada +2
There has been a growing evidence for the existence of magnetic fields in the extra-galactic regions, while the attempt to associate their origin with the inflationary epoch alone…
Primordial black holes as biased tracers
Yuichiro Tada, Shuichiro Yokoyama
Primordial black holes (PBHs) are theoretical black holes which may be formed during the radiation dominant era and, basically, caused by the gravitational collapse of radiational…
