Constraints on accreting primordial black holes with the global 21-cm signal
Yupeng Yang
We investigate the effect of accreting primordial black holes (PBHs) on the thermal history of the intergalactic medium (IGM), including the accretion of baryonic matter and dark m…

Constraints on primordial black holes and curvature perturbations from the global 21cm signal
Yupeng Yang
The recent observations of the global 21cm signal by EDGES and gravitational waves by LIGO/VIGO have revived interest in PBHs. Different from previous works, we investigate the inf…

Constraints on the small scale curvature perturbation using Planck-2015 data
Yupeng Yang
The particles emitted from PBHs through the Hawking radiation have interactions with the particles present in the Universe. Due to the interactions, the evolution of the intergalac…
