Description
We consider energy deposition of high energy electrons and photons in the Universe. We carry out detailed calculations of fractions of the initial energy of the injected electron or photon which are used to heat, ionize, and excite background plasma in the early Universe for various ionization states (ionization fraction=10-3-1) and redshifts (z=100-1000).
