Frontiers in 21 cm Cosmology, 10-18 December, 2018 at KodaiKanal Observatory

About this school and workshop

One of the most important eras in cosmic evolution is marked by the formation of the first luminous objects and the associated transition of the universe from a neutral to ionized phase. Following the history of HI during these epochs: the Cosmic Dawn (CD), the Epoch of Reionization (EoR) and the Post Reionization Era (PEoR) holds the key to understand the physics of the reionization as well as the first luminous objects and their radiation mechanisms. Observationally, the probe to HI is the 21-cm radiation. On the observational front,there is an ongoing effort across the world to detect the 21cm fluctuations. There are also efforts to model the first astrophysical sources during cosmic dawn and their effect on the IGM during and post reionization using several semi analytical and numerical techniques.
The six days school is intended to expose young graduate students, post docs and early researchers to various observational theoretical and numerical aspects of the field of 21cm cosmology,EoR and post EoR. The subsequent two day workshop is aimed at bringing together researchers in the Indian community working in the field of 21cm Cosmology.

Venue for the School/Workshop

The Kodaikanal Solar Observatory (KSO) of the Indian Institute of Astrophysics is located in Palani range of hills in Southern India. It was established in 1899 as a Solar Physics Observatory and all the activities of the Madras Observatory were shifted to Kodaikanal.
