PROFILE

Devesh Sharma

Ph.D. Astrophysics student at IIT Indore, currently working on solar atmosphere modelling and wave dynamics using magnetohydrodynamic (MHD) simulations with the PLUTO code. My work focuses on wave propagation, mode conversion, and energy transport in magnetized plasma relevant to coronal heating. I have also worked on cosmological parameter estimation using MCMC methods within the ΛCDM framework, and asteroseismic analysis of stellar light curves from Kepler and TESS to study stellar oscillations and properties.

I'm a Master of Science-Reseach (MS-R) student at IISER Tirupati, currently working on galaxy dynamics in an Astrophysics group. I'm primarily focusing on observational analysis, theoretical/computational modeling, and simulations. Apart from that I'm also interested in nuclear and plasma physics.

Projects

Below are research projects I have worked on:

Solar Atmosphere Modelling and Wave Dynamics

Supervisor: Dr. Bhargav Vaidya
Magnetohydrodynamic descriptions of the solar atmosphere capture large-scale plasma behavior, but accurately modeling wave propagation and energy dissipation in stratified, magnetized environments remains a challenge. We are developing 2.5D MHD simulations using the PLUTO code to study wave dynamics, mode conversion, and the mechanisms of energy transport and dissipation relevant to coronal heating.

Cosmological Parameter Estimation using MCMC

Instructor: Dr. Suman Majumdar
Observational constraints on cosmological models rely on accurately relating distance measures to redshift, with Type Ia Supernovae serving as key standard candles. In this project, I modeled the luminosity distance–redshift relation using supernova data and implemented a custom Markov Chain Monte Carlo (MCMC) algorithm to explore parameter space. Which allowed for placing constraints on cosmological parameters within the ΛCDM framework.

Asteroseismic Analysis of Stellar Light Curves

Supervisor: Dr. Ashutosh Vishwabandhu
Stellar oscillations provide a powerful probe of internal structure, but extracting reliable information from photometric data requires careful time-series analysis. In this project, I analyzed Kepler and TESS light curves using the LightKurve library, identified oscillation modes through power spectrum and autocorrelation techniques, and estimated stellar parameters using asteroseismic scaling relations.
