Can asteroid-mass PBHDM be compatible with catalyzed phase transition interpretation of PTA?

Jiahang Zhong, Chao Chen, Yi-Fu Cai

Primordial black holes (PBHs) can catalyze first-order phase transitions (FOPTs) in their vicinity, potentially modifying the gravitational wave (GW) signals from PTs. In this stud…

Stochastic Axion-like Curvaton: Non-Gaussianity and Primordial Black Holes Without Large Power Spectrum

Chao Chen, Anish Ghoshal, Gianmassimo Tasinato +1

We discuss a mechanism of primordial black hole (PBH) formation that does not require specific features in the inflationary potential, revisiting previous literature. In this mecha…
