Exploring the wonders of the cosmos through computational astrophysics
Hi! Welcome to my website! I'm an observational and computational astrophysicist in construction. I enjoy playing cricket, swimming, and listening to Hindi music in my free time. I'm also a nerd, always eager to explore the latest advancements in STEM.
You can learn more about my work here.
Pursuing my Master's in Physics from Savitribai Phule Pune University enabled me to be a part of the Inter-University Centre for Astronomy and Astrophysics (IUCAA), the hub for Astrophysics research in India, which allowed me to investigate the extended emissions in high-redshift Quasars using Chandra as a probe.
To improve the detection pipeline and make it more efficient, I enrolled for my Master's thesis project with Dr. Vaidehi Paliya at IUCAA. I employed Bayesian statistics and the Low Counts Image Reconstruction and Analysis (LIRA) algorithm using Python and necessary CXC tools for data processing to develop a sophisticated pipeline to detect extended emissions in high-redshift radio-loud Quasars using Chandra X-ray data. The pipeline can detect comprehensive emissions with improved accuracy by employing MCMC analysis and observing the 2D Poission deviations from the baseline model. It also generates higher-resolution data using LIRA for better morphological analysis of the emissions.
Recently, I have been working with esteemed cosmologists of India, Dr. Saibal Ray, Dr. Anil Kumar Yadav, and Dr. Lokesh Kumar Sharma, to get collaborative exposure. In this project, we aim to derive cosmological models that can study the universe's expansion rate. My role is to develop a pipeline to calculate the cosmological parameters for the derived model using observational datasets. I used my knowledge of Bayesian statistics from my previous project to make the pipeline even more accurate. The results resonated with the current observational studies released by the Planck association, which confirmed the accuracy of the channel as well as the derivation of the model. It resulted in the preparation of multiple manuscripts. This experience helped me expand my data analysis and Bayesian analysis skills, which will benefit my research aspirations.
To further understand and search for the answer to the extended diffused emissions, such as radio halos and relics detected at the central region of AGNs and large-scale structures of the Galaxy Clusters (GCs), I am working with Dr. Viral Parekh, NRAO. This project involves the morphological analysis of the GCs center in the Radio and X-ray bands using NVSS, VLASS, and CXC data from the MGCLS clusters and MaDCoWS Catalogs, conducting a comprehensive analysis of the Radio Halos and relics. This analysis will help reveal the processes behind the unknown emissions observed and provide me with the new exposure necessary for my future research endeavors.
