Professor Sugata Kaviraj serves as Professor of Astrophysics at the University of Hertfordshire within the Department of Physics, Astronomy and Mathematics (School of Physics, Engineering & Computer Science), while concurrently holding a Senior Research Fellowship at Worcester College, Oxford. His research integrates multi-wavelength observations with galaxy formation models and machine learning techniques to advance understanding of extragalactic astrophysics.
Kaviraj earned his PhD from the University of Oxford in 2006, followed by research fellowships at Oxford (Leverhulme Early-Career and Junior Research Fellowships), University College London (1851 Royal Commission Fellowship), and Imperial College London (ICL Research Fellowship) before joining Hertfordshire in 2013.
His research program centers on galaxy formation and evolution, with specific expertise in extra-galactic globular clusters, black hole–galaxy co-evolution, supernova/AGN feedback mechanisms, and citizen science applications. Kaviraj leads multiple science themes within Galaxy Zoo and has held leadership roles in the GALEX, MUSYC, and WFC3 Early-Release Science collaborations.
Recent publications reveal sustained focus on merger processes across cosmic time, particularly examining minor mergers' role in star formation budgets and structural evolution of galaxies through analyses of dusty spheroids, high-redshift systems, and low-mass analogues using data from LSST, Herschel-ATLAS, and CANDELS surveys.
Notable scientific recognition includes:
- Leverhulme Early-Career Fellowship
- Junior Research Fellowship at Worcester College
- Research Fellowship from the 1851 Royal Commission
- ICL Research Fellowship
- Royal Astronomical Society's Winton Capital Award (2011)
Kaviraj currently directs seven active research projects totaling over £2.5M in funding, including the Royal Commission-funded "Simulating Galaxies and Supermassive Black Holes in the Multi-Messenger Era" (2024-2027) and UK involvement in LSST Phase C. His grant portfolio demonstrates sustained leadership in observational programs like the SWIFT study of green peas and IRAM survey of dust-lane galaxies.
As co-Chair of the LSST Galaxies Science Collaboration and key member of the Centre for Astrophysics Research (CAR), Kaviraj maintains extensive international collaborations through Herschel-ATLAS, CANDELS, mJIVE-20, Horizon-AGN, and Galaxy Zoo consortia, driving multi-wavelength approaches to galaxy evolution studies.
