My work, in general, involves leveraging cosmological-scale hydrodynamical simulations (EAGLE and IllustrisTNG) to investigate scientific questions dealing with galaxy formation and halo assembly. At IA, I am primarily investigating the prospects of recovering dark matter properties of galaxy clusters from observational data, particularly the intracluster light, using the IllustrisTNG simulations. This is in the context of the LSST survey that is poised to provide optical observations of galaxy clusters down to unprecedented sensitivities, enabling high-fidelity mapping of the diffuse intracluster light across the whole halo. Additionally, I am involved in studies that explore various aspects of galaxy evolution and cosmology, including the signatures of halo assembly bias in galaxy clustering, impact of galaxy interactions on their radial profiles, environmental dependence of asymmetry in H I, the origins of diffuse ionised gas around galaxies, and the relationship between dynamical state of dark matter haloes and galaxy–halo alignment. Feel free to get in touch for potential collaborations!
