Research Experience
-
Study of Multiphase CGM Absorber Tracing 106 K Plasma
Supervisor: Dr. Sowgat Muzahid, IUCAA, Pune- Analysed and studied the a multiphase absorber system tracing 106K plasma
- I was able to resolve previously undetected cool gas phase in the HST COS spectrum.
- Learnt about Voigt profiles and fitting absorption lines to extract physical properties of the cloud.
- Performed photoionization modelling using CLOUDY and compared the computed results to the observed spectra.
-
Modelling Magnetic Reconnection using PLUTO
Supervisor: Dr. Amit Shukla, IIT Indore- Solved MHD equations for magnetic reconnection.
- Analysed the dependence of various parameters on the reconnection.
- Got familiarized with the usage of PLUTO performed various HD/MHD simulations on it including - Hydrodynamical Jet Flow, the Kevin-Helmholtz Instability and MHD Blast Waves
-
Visualising Geodesics in Schwarzschild Spacetime
KSP6 Project- We explored General Relativity by simulating the motion of particles and light in the curved spacetime around a non-rotating black hole, described by the Schwarzschild metric.
- We computationally solved the geodesic equations to calculate trajectories near key features, such as the Event Horizon.
-
Spectral Modelling of Type Iax Supernovae
Supervisor: Dr. Kuntal Misra, ARIES, Nainital- The project involves detailed spectral analysis and modelling of type Iax supernova ejecta, using a 1D radiative-transfer code TARDIS, to understand its mechanism and progenitors.
- Worked extensively on radiative-transfer modelling through Monte-Carlo methods, MCMC fitting of emission lines and spectral analysis.
- We were able to show that abundance stratification in the early epoch ejecta could explain certain previously un-reproducable spectral deviations.
- Results published in the Journal of Astrophysics and Astronomy.
- Link to the Final Report.
-
Earth as an Exoplanet
Supervisor: Dr. Jayesh Goyal, SEPS, NISER, Bhubaneswar- A project studying the diurnal variation of Earth’s disk integrated emission spectra to model how the Earth would look like as a directly imaged exoplanet.
- Worked directly with INSAT-3D satellite data to analyse earth’s disk integrated spectrum over time.
- Was familiarized with large-scale data analysis of Earth’s SED data.
-
Markovian Agent Based Monte Carlo Simulations
Supervisor: Dr. Colin Benjamin, SPS, NISER- Developed for Markovian agent based Monte-Carlo algorithms for various cases of reaction-diffusion models, population dynamics, and epidemic spreading inspired by Swailem, M. et al. (2025), as part of the computational physics course.
- Improved the original algorithm to support parallel GPU based computation to analyse larger scale Monte-Carlo dynamics.
- More details available on the project website.
-
Sample-Based Guided Quantum Walk for Combinatorial Optimization
Supervisor: Dr. Colin Benjamin, SPS, NISER- Tested and optimised the Sample-Based Guided Quantum Walk Algorithm on various combinatorial optimization problems based on Nzongani, U. et al. (2025), as part of the computational physics course.
- More details available on the project website.
