I am a faculty at the Physical Research Laboratory (PRL), seeking answers to some fundamental questions such as how and where do stars or cluster of stars form in the Universe, and how these stars influence the interstellar medium and regulate the star formation processes of the host Galaxy.

I look to the above problems with astronomical observations using ground and space observatories in a huge range of wavelengths. In particular, I use telescopes observing in the radio, millimeter, infrared, and optical domain to get information about the stars, and the gas and dust associated to them. You can find more details on my work on my research page and all my publications can be found on my publication page.

On the formation massive clusters in GMCs: an observational prospective on G148 GMC.
Clouds more massive than about 10^5 Msun are potential sites of massive (10^4 Msun) cluster formation. In a recent work, using various observational metrics, we discuss the cluster formation mechanisms and cluster forming potential of the Giant Molecular Cloud (GMC) G148.24+00.41. Comparing our results with the models of star cluster formation, we conclude that the GMC has the potential to form a star cluster in the mass range ∼ 2000–3000 Msun through dynamical hierarchical collapse and assembly of both gas and stars. For details, see Rawat et al. 2023.

Proper motion of Tr-37 members @ GAIA
Kinematics of stellar members in the Trumpler-37 cluster formimg complex
In a recent work, using Gaia-DR3 data and machine learning tools, we identified members of Tr-37 young cluster over 7.1 degree^2 area. Doing kinematic analysis, we find that cluster members are expanding at a rate of 1.1 km/s, which is found to be slower compared to the expansion velocity, ~5 km/s, of the molecular gas in the complex. We discussed that this slow expansion of the cluster is likley due to the fact that most of the cluster members are still bound and the cluster is still not significantly dynamically evolved. For details, see Das et al. 2023.
