Constraints on small-scale primordial power by annihilation signals from extragalactic dark matter minihalos
Tomohiro Nakama, Teruaki Suyama, Kazunori Kohri +1
We revisit constraints on small-scale primordial power from annihilation signals from dark matter minihalos. Using gamma rays and neutrinos from extragalactic minihalos and assumin…

Limits on primordial black holes from distortions in cosmic microwave background
Tomohiro Nakama, Bernard Carr, Joseph Silk
If primordial black holes (PBHs) form directly from inhomogeneities in the early Universe, then the number in the mass range is severely constrained by upp…

Shedding light on the small-scale crisis with CMB spectral distortions
Tomohiro Nakama, Jens Chluba, Marc Kamionkowski
The small-scale crisis, discrepancies between observations and N-body simulations, may imply suppressed matter fluctuations on subgalactic distance scales. Such a suppression could…
