Primordial Black Holes and Second-order Gravitational Waves in Axion-like Hybrid Inflation
Waqas Ahmed, Anish Ghoshal, Umer Zubair
We investigate the possibility that primordial black holes (PBHs) can be formed from large curvature perturbations generated during the waterfall phase transition in a hybrid infla…

Constraints on primordial curvature spectrum from primordial black holes and scalar-induced gravitational waves
Zhu Yi, Qin Fei
The observational data of primordial black holes and scalar-induced gravitational waves can constrain the primordial curvature perturbation at small scales. We parameterize the pri…

Primordial Black Holes and Gravitational Waves in Hybrid Inflation with Chaotic Potentials
Waqas Ahmed, M. Junaid, Umer Zubair
We study the formation of primordial black hole (PBH) dark matter and the generation of scalar induced secondary gravitational waves (SIGWs) in a non-supersymmetric model of hybrid…
