Soumya Shreeram

I am an astrophysicist and research software developer, and I am currently working as a data scientist. I completed my PhD in 2025 at the Max Planck Institute for Extraterrestrial Physics, where I focused on forward modelling the hot circumgalactic medium in X-rays. Before this, I completed my Master's in Physics at EPFL in Switzerland and my Bachelor's in Physics with Astrophysics at the University of Manchester in the UK.

My work on various science projects over the years are summarized below.

Science Projects

My work on the hot CGM

Using my IllustrisTNG-based lightcone, I led a study on the projection effects in the X-ray emitting hot CGM around galaxies.

Study of the Galactic Centre Region of the Milky Way Using Slitless Spectroscopy

This project, conducted at MPIA, Heidelberg, Germany, aimed to distinguish between early and late-type stars in the Galactic Centre Region using Slitless Spectroscopy.

Pulsars: radio astronomy

This experiment investigates pulsar properties. The data for the experiment was obtained from the radio telescopes at Jodrell Bank Observatory, Cheshire.

Studying Qubit Interactions with Multimode Cavities Using QuTiP

My work on using QuTiP, a quantum computing framework, to simulate interactions between two-qubits coupled with each other via three resonators.

AI/ML in astronomy

During my masters, I worked on classifying SDSS spectra using Neural networks.
