Research in Physical Sciences at Bose Institute has a long and proud history. The seminal work of its illustrious founder, Acharya Jagadish Chandra Bose, in millimeter waves was followed up by internationally acclaimed research in nuclear physics, cosmic ray physics and magnetism even in pre-independence India. With the passage of time and the induction of new members in the faculty, research in Physical Sciences at Bose Institute has also become quite diverse.

The Centre for Astroparticle Physics and Space Science (CAPSS) has been established at Bose Institute to pursue focussed research in Astrophysics, Cosmology, Quantum Physics, Radiophysics and climate related topics.
