$O (10) M_{⊙}$ 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 $M \sim 30 M_{⊙}$ 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 $(r \geq 1 0^{- 3})$ on the CMB scale can be generated even during extremely low energy inflation which saturates the BBN bound $ρ_{\rm…

Inflationary Primordial Black Holes as All Dark Matter

Keisuke Inomata, Masahiro Kawasaki, Kyohei Mukaida +2

Following a new microlensing constraint on primordial black holes (PBHs) with $\sim 1 0^{20}$ -- $1 0^{28} g$ ~[1], we revisit the idea of PBH as all Dark Matter (DM). We have…
