CMB polarization non-Gaussianity from accreting primordial black holes
Trey W. Jensen, Yacine Ali-Haïmoud
Primordial black holes (PBHs) would induce non-Gaussianity in the cosmic microwave background (CMB) by sourcing recombination perturbations spatially modulated by relative velociti…

CMB temperature trispectrum from accreting primordial black holes
Trey W. Jensen, Yacine Ali-Haïmoud
It is known that Primordial Black Holes (PBHs) can leave an imprint on Cosmic Microwave Background (CMB) anisotropy power spectra, due to their accretion-powered injection of energ…

Perturbed recombination from inhomogeneous photon injection and application to accreting primordial black holes
Trey W. Jensen, Yacine Ali-Haïmoud
Exotic electromagnetic energy injection in the early Universe may alter cosmological recombination, and ultimately cosmic microwave background (CMB) anisotropies. Moreover, if ener…
