Description

Reionization is a unique epoch in Cosmology and studies of the epoch of reionization (EoR) can tell us important information about ionization history, first luminous objects, and structure formation in the early Universe. However, the EoR is still poorly understood so far. In light of this, we investigate to what extent experiments observing at different wavelengths can detect the EoR signatures that could be produced by various physical processes, such as scattering between photons of the cosmic microwave background and free electrons that were stripped from neutral hydrogen atoms by ultraviolet radiation, stellar emission from the primeval objects and 21 cm emission from the neutral hydrogen content surrounding the ionizing regions. In this talk, I will show a few newly developed techniques for detecting the EoR signatures at different wavelengths.
