Collaborating research institutes, centres and groups

Astronomy Group

We aim to understand the nature of cosmic objects and the life cycle of stars including the impact of surrounding galaxies.

Multiwavelength Accretion and Astronomical Transients

Our group carries out frontline research on observational astrophyics. We study black holes across the electromagnetic spectrum, the formation and growth.
