【 摘 要 】

The high energy gamma rays from blazar affects the intergalactic medium (IGM) to large distances at different redshifts. The blazar radiation has been taken as the result of synchrotron and Inverse Compton scattering of electrons. It is found that the intergalactic medium is clumpy. Our estimated values lie within the suggested limit of ΩIGM0.03 at redshift z 3.
