Advanced 21-cm Cosmology

school and workshop

The 21-cm line from the neutral hydrogen (HI) atom is an important observational probe of the evolution of the universe from about 0.4 million years after the Big Bang until today. Future observations will shed light upon important cosmological epochs such as the cosmic dark ages, the epoch of cosmic dawn and the Epoch of Reionization (EoR) of the universe. Keeping in view the ongoing global efforts for detecting the cosmological 21-cm signal, there is an active participation of the Indian community working on several aspects of theory, simulation, and observations of these epochs. This school plus workshop is a biannual event organised by the Indian SKA Science Working Group in cosmology to facilitate the exchange of updates on ongoing research, foster new collaborations and encourage Ph.D. students and early post-docs to share their work and gain exposure in the field.

The school will consist of a series of theory lectures, hands-on demonstrations and discussions on different methods of analytical modelling, simulations, observations, data reduction and statistical inference for multi-wavelength observations of this early phase of our Universe.
