III Saha Theory Workshop: Aspects of Early Universe Cosmology

16 Jan 2017, 09:00 → 20 Jan 2017, 21:00 Asia/Calcutta

Auditorium (Saha Institute of Nuclear Physics)

Theory Division of Saha Institute of Nuclear Physics will host its third "Saha Theory Workshop: Aspects of Early Universe Cosmology" from 16th January to 20th January, 2017. The workshop is intended for experts who are actively working in this field. We particularly encourage participation from young members who are pursuing research in this area. The workshop will focus on several theoretical aspects of early universe cosmology, how present and forthcoming data can guide us to unravel the mystery of early Universe. A special session will be dedicated to how Indian experimental collaborations can contribute to this effort. 

Participation is by invitation only and is restricted to practitioners in the field of early Universe cosmology.

If you are interested to join in the workshop, you may write to the organisers. Due to limited financial and logistical resources, we might not be able to accommodate every request. 

Note: For Registration, you do not need any indico account.
