The department of Astrophysics, Cosmology and Fundamental Interactions (COSMO) is a newly-formed department in CBPF. COSMO is an active department of 9 faculty members, holding weekly seminars and journal clubs in various areas, organizing regular conferences and workshops, supervising many postgraduate students and postdoctoral researchers, attracting a dynamic flow of national and international visitors, establishing collaborations with international research groups and institutions as well as lecturing advanced post-graduate courses. The research carried out in COSMO comprises (but is not limited to) the following areas:
