Research

Second project of PhD. Analyzed blue straggler sequences in HST color–magnitude diagrams of 56 Galactic globular clusters to test the statistical significance of reported double blue straggler sequences. The research paper summarizing the analysis is published in the AJ (see Publications). 

First Project of PhD. Analyzed more than a decade of Chandra observations of the globular cluster Terzan 5 to identify and classify X-ray sources through photometric, spectral, and variability analyses.  The research paper summarizing the analysis is published in the ApJ (see Publications).

Project for my MS thesis. Conducted a spectroscopic study of 39 blue straggler stars in NGC 3201, deriving radial velocities, atmospheric parameters, metallicities, and the first [Mg/Fe] estimates for the cluster’s BSS population. The research paper summarizing our analysis has been published in RMxAA (see Publications).

Project of my Mitacs Globalink Research Internship during the summer of 2023. Analyzed Chandra observations of NGC 362 to identify X-ray sources and their optical/UV counterparts using HUGS photometry, including qLMXBs, AGNs, red stragglers, and active binaries.  The research paper summarizing this analysis has been published in MNRAS (see Publications).

Project of my IASc-INSA-NASI Summer Research Internship during the summer of 2022. Performed multi-wavelength SED analysis using data from the MPG/ESO 2.2-m telescope, AstroSat/UVIT, and Swift/UVOT, leading to the first discovery of blue lurkers in a globular cluster. The research paper summarizing this analysis has been published in MNRAS Letters (see Publications).

This project was undertaken as part of the course requirements for ASTRO565 at UAlberta, taught by Prof. Natasha Ivanova during Fall 2024. Studied stellar populations and collision products in a simulated 10 Gyr globular cluster using MESA.

This group project was undertaken under the supervision of Dr. Ana Paulino-Afonso during the IAstro summer program in 2023. Analyzed local and global properties of 21 Type Ia supernova host galaxies using integral-field spectroscopy data from the VLT/MUSE.

This group project was undertaken during the Krittika Summer Projects 2022, conducted by the IIT Bombay Astronomy Club. Studied solar flares using Chandrayaan-2 XSM data and reproduced existing flare-detection models to analyze different types of stellar flares.

This duo project was undertaken as part of the course requirements for DSE302 at IISER Bhopal, taught by Dr. Tanmay Basu during Winter 2022. Extracted and analyzed parameters from the Kepler dataset in the NASA Exoplanet Archive and applied regression models to predict exoplanet orbital semi-major axes.

This group project was undertaken as part of the course requirements for DSE313 at IISER Bhopal, taught by Dr. Vaibhav Kumar during Fall 2021. Developed chronologically constrained evolutionary CNN models for galaxy classification, achieving an accuracy of 82.7% in three-class classification.

This duo project was undertaken as part of the course requirements for DSE309 at IISER Bhopal, taught by Dr. Parthiban Srinivasan during Fall 2021. Developed an ontology in Owlready2 for stellar classification based on temperature, color, and dominant spectral lines following the Harvard Spectral Classification scheme.

This group project was undertaken during the Krittika Summer Projects 2021, conducted by the IIT Bombay Astronomy Club. Performed PSF photometry on GROWTH-India Telescope data using SExtractor and PSFEx, and generated g-, r-, and i-band light curves for the supernova SN2018hna.
