Spectral Modelling of Type Iax Supernovae

Supervisor: Dr. Kuntal Misra, ARIES, Nainital

(Dec 2023 - May 2025)

Here, we used spectral modelling to study mixing in supernova ejecta, particularly in Type Iax systems, using a 1D radiative transfer based spectral modelling software TARDIS. Understanding abundance mixing can help in uncovering the dynamics of the explosion of this peculiar supernova sub-class.

Results .

Study of a Multiphase CGM Absorber Tracing Hot Plasma

Supervisor: Dr. Sowgat Muzahid, IUCAA, Pune

(May 2025 - )

In this project, I analysed HST COS spectra of QSO sightlines to identify and resolve multiphase absorber systems to study the properties of Circumgalactic Medium of Galaxies. Specifically, I focused on a system tracing 10⁶K Plasma, which contains a broad Lyα absorption system.

Modelling Magnetic Reconnection using PLUTO

Supervisor: Dr. Amit Shukla, IIT Indore

(May 2025 - July 2025)

I performed 2D MHD simulations using PLUTO to study magnetic reconnection and its effect on particle acceleration. I got to learn the physics behind it as well as familiarize myself with computational solving MHD equations.

Visualising Geodesics in Schwarzschild Spacetime

(May 2025 - July 2025)

As a part of Krittika Summer Project 6.0 organized by Krittika Astronomy Club, IIT Bombay, I worked on computational simulations of the motion of particles and light around the curved spacetime of a non-rotating black hole, using General Relativity.

Applications of Numerical Calculus in Multidisciplinary Problems

Project done as a part of the Computational Physics course (P346), where we numerically analysed real-world problems using computational methods.
