Rayleigh Scattering Cross Section Redward of Ly by Atomic Hydrogen
Hee-Won Lee, Hee Il Kim
We present a low energy expansion of the Kramers-Heisenberg formula for atomic hydrogen in terms of , where and are the angular frequencies corresponding to the…
Primordial black holes under the double inflationary power spectrum
Hee Il Kim
Recently, it has been shown that the primordial black holes (PBHs) produced by near critical collapse in the expanding universe have a scaling mass relation similar to that of blac…
Relics of cosmological quark-hadron phase transition
Hee Il Kim, Bum-Hoon Lee, Chul H. Lee
We propose that the amplified density fluctuations by the vanishing sound velocity effect during the cosmological quark-hadron phase transition lead to quark-gluon plasma lumps dec…
Diffuse -ray background and primordial black hole constraints on the spectral index of density fluctuations
Hee Il Kim, Chul H. Lee, Jane H. MacGibbon
We calculate the flux of -rays emitted from primordial black holes (PBHs) which are formed by a ``blue'' power-law spectrum of density fluctuations in the early universe. Gamma-…
