RESEARCH INTERESTS:

Dynamics and evolution of clusters of galaxies, groups and early-type galaxies using multi-wavelength observations. The broad areas of interest include:
• Thermodynamics of clusters, groups and giant ellipticals and effect of non-gravitational processes.
• Central AGN feedback mechanism in clusters, groups and giant ellipticals.
• Cold gas in giant ellipticals: Origin and its role in AGN feedback cycle.
• Central metallicity drops in clusters and groups of galaxies.
• Scaling relations in clusters, groups and ellipticals.
• Development of new statistical analysis techniques for analyzing X-ray emission from clusters, groups and giant ellipticals using Bayesian analysis, MCMC.
• Substructures and mergers in galaxy clusters.
• Large-scale radio emission from clusters and its connection with mergers.
