The Axion-Photon Mixing and the Extragalactic Magnetic Background: Plateau Regimes, Resonances, and Non-Gaussian Boosts
Andrea Addazi, Yi-Fu Cai, Salvatore Capozziello +2
We present an analytical treatment of Axion-Like-Particle (ALP)--photon mixing with extragalactic background light (EBL) attenuation for constant, Gaussian-stochastic, and non-Gaus…
Primordial Black Hole Formation from the Upward Step Model: Avoiding Overproduction
Xiaoding Wang, Xiao-Han Ma, Yi-Fu Cai
We investigate the formation of primordial black holes (PBHs) in an upward step inflationary model, where nonlinearities between curvature perturbations and field fluctuations intr…
Gravitational waves from primordial black hole isocurvature: the effect of non-Gaussianities
Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma +3
Ultra-light primordial black holes (PBHs) with masses can dominate transiently the energy budget of the Universe and reheat the Universe throug…
Primordial black holes and induced gravitational waves in non-singular matter bouncing cosmology
Theodoros Papanikolaou, Shreya Banerjee, Yi-Fu Cai +2
We present a novel model-independent generic mechanism for primordial black hole formation within the context of non-singular matter bouncing cosmology. In particular, considering…
New probe of non-Gaussianities with primordial black hole induced gravitational waves
Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma +3
We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light () primordial…
