Stochastic inflation with an extremely large number of -folds
Naoya Kitajima, Yuichiro Tada, Fuminobu Takahashi
We propose a class of single-field, slow-roll inflation models in which a typical number of -folds can be extremely large. The key point is to introduce a very shallow local min…
Primordial black hole tower: Dark matter, earth-mass, and LIGO black holes
Yuichiro Tada, Shuichiro Yokoyama
We investigate a possibility of primordial black hole (PBH) formation with a hierarchical mass spectrum in multiple phases of inflation. As an example, we find that one can simulta…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
