CMB cross-correlations as a probe of PBH scenarios
Ogan Özsoy, Gianmassimo Tasinato
We propose a new method for probing inflationary models of primordial black hole (PBH) production, using only CMB physics at relatively large scales. In PBH scenarios, the primordi…

Primordial black holes as dark matter and gravitational waves from bumpy axion inflation
Ogan Özsoy, Zygmunt Lalak
We consider a mechanism for producing a significant population of primordial black holes (PBHs) and an observable stochastic gravitational wave background (SGWB) within string theo…
