Description |
The redshifted 21-cm signal from neutral hydrogen in the intergalactic medium (IGM) is the most promising probe of the Epoch of Reionization. It has the ability to reveal many of the unknown facts about this epoch such as properties of the early sources of radiation, thermal and ionization states of the IGM. Radio telescopes such as LOFAR, MWA are providing stronger upper limits on the 21-cm power spectrum. I will be talking about how these measurements are used to constraint the states of the IGM during this epoch. |
