Prof. More's research focusses on cosmology and the formation and evolution of galaxies, both observationally and theoretically. Astronomical observations in the last couple of decades indicate that a large portion (~96%) of the energy density of the Universe is made up of two mysterious and poorly understood components: dark matter and dark energy. His research work has helped understand the connection between the observable properties of galaxies and the dark matter clumps in which galaxies live. This has allowed the use of galaxies as shining beacons to explore the parameters that describe the dark Universe. He is a member of the Subaru Hyper Suprime-Cam survey as well as the upcoming Large Synoptic Survey Telescope project, two ambitious projects which aim to map out dark matter in the Universe and understand dark energy.

Prof. Shasvath J. Kapadia’s interests span a broad range of topics in gravitational-wave astronomy, astrophysics, cosmology and data analysis. In particular, he is interested in exploring novel ways in which gravitational-wave astronomy can interface with other branches of astrophysics. He has worked on identifying gravitational-wave signals in noisy data and identifying eccentric gravitational-wave signals, with machine learning; gravitational-lensing of gravitational-waves and corresponding electromagnetic counterparts; rapid classification of compact binary merger signals into astrophysical categories; early-warning of compact binary mergers to assist rapid electromagnetic follow-up; constraining rates of compact binary mergers; using the stochastic gravitational-wave background to constrain aspects of early-universe cosmology; testing general relativity with gravitational-waves, in particular, constraining the time-variation of the gravitational constant; among others.

Prof. De is an experimentalist in the areas of atomic-molecular-optical (AMO) physics with expertise in laser cooling and trapping of atoms & ions, degenerate quantum gasses, quantum optics and time & frequency metrology. His present research interests are (i) quantum metrology on ultra-stable optical reference that has applications in fundamental sciences and high-end technologies e.g. quantum communication; (ii) developing quantum-enhanced technologies; (iii) precision measurements for probing temporal constancy of dimensionless fundamental constants, geodesy, violation of Lorentz symmetry and (iv) studying quantum dynamics using trapped atoms/ ions.

Dr. Anupam Bhardwaj works on precision stellar astrophysics and the cosmic distance scale using multi-wavelength photometric and spectroscopic observations of classical pulsating variable stars. His current research is focussed on improving the calibration of stellar standard candles in the first rung of the cosmic distance ladder used to determine the present expansion rate of the Universe. He uses Cepheid, RR Lyrae, and Mira variable stars as stellar population tracers for Galactic archaeology and near-field cosmology with observational data from 4-8 m class telescopes. He is involved in several multi-wavelength time-domain surveys such as VVV, ZTF, LSST, and in specific projects with TESS and Gaia space missions. His theoretical interests include stellar evolution and pulsation modeling with the Modules for Experiments in Stellar Astrophysics (MESA), open-source 1D stellar evolution code
