Abstract: |
The reionization of the Universe, it is believed, occurred by the growth of ionized regions (bubbles) in the neutral intergalactic medium (IGM). Using the method of Datta, Bharadwaj & Choudhury (2007) for detecting ionized bubbles in 21-cm maps we use various realistic simulations of Hi distribution surrounding an ionized bubble to study the effect of Hi fluctuations on the blind search for ionized bubbles in 21-cm maps. Results are presented for 1000 hours of GMRT observations at redshift z = 6 which corresponds to frequency 203 MHz. |
