About me

[Google Scholar Page]

I am Aryan, a 5th year BS-MS physics major at Indian Institute of Science Education and Research (IISER), Mohali,India
Interested in Black Holes and Active Galactic Nuclei (AGNs), including their accretion disks and jets, focusing on the \textbf{theoretical and computational aspects} of their dynamics and stability.
I am also interested in creative writing including short stories and poems.

Experience

I have worked on projects involving numerical simulations of AGN jets, N-Body system and data analysis in Galactic Dynamics.

2025

  • RMHD Simulations of AGN Jets and Studying Instabilities (Ongoing)
    • Dr. Pankaj Kushwaha | Indian Institute of Science Education and Research (IISER) Mohali, India
    • Description: The project aims to use PLUTO code to simulate AGN jets and do a detailed study of the instabilities and performing a linear stability analysis of these jets. The goal is to understand what keeps these jets so stable, even showing very high degrees of collimation, keeping them stable to distances of several hundred kiloparsecs.

2024

  • Studying Bar Pattern Speed in Galaxies in Different Environments using TNG50
    • Prof. Mousumi Das | Indian Institute of Astrophysics - IIA , Bangalore, India
    • Description: For the barred galaxies in the state-of-the-art simulation, Illustris TNG50, their neighbour galax- ies were identified. They were further classified on the basis of neighbour count. The goal of this project is to study how bar pattern speed in galaxies is affected by their environment. The environment could include other barred galaxies as well. The bar speeds are to be calculated using the Tremaine–Weinberg method.

2023

  • Studying the identification, evolution and formation of Boxy/Peanut Bulges in TNG50
    • Dr Ankit Kumar | Indian Institute of Astrophysics - IIA, Banglore, India (Later, at UNAB and USM, Chile)

  • Many body simulations and their applications in characterising chaos and mean - motion resonances in meteoroid streams
    • Prof. Jasjeet Singh Bagla | IISER, Mohali, India

  • (School) The Fascinating World of Flows (basic tools to describe flows, how they turn unstable and turbulent)
    • Prof. Rama Govindarajan (ICTS-TIFR, India) and Prof. Samriddhi Sankar Ray (ICTS-TIFR, India)

  • (Workshop) Gravitational Wave Open Data Workshop (3 day workshop) (using gravitational-wave data for analysis)
    • GWOSC (formerly, LIGO Open Science Center)
    • Description I learned how to work with Illustris TNG50 data and used it to study the evolution of Boxy/Peanut Bulges in barred galaxies. The bars were identified by doing the Fourier decomposition of the stellar face-on density profiles of the galaxies, measuring their bar strength. Then gaussian filter was used to identify the BP/X structures. Then differences in properties like total stellar mass etc were compared for the BP/X and non-BP/X galaxies.

2022

  • Made a few features of the database app (written by Dr Bhardwaj for CFSL, Chandigarh) windows-compatible
    • Dr Vishal Bhardwaj | IISER, Mohali, India

    Conferences and Meetings

    • 42nd meeting of the Astronomical Society of India (ASI) jointly by Indian Institute of Science (IISc), Indian Space Research Organisation (ISRO) and Jawaharlal Nehru Planetarium (JNP) at Bengaluru
        • 31 January 2024 - 4 February 2024

    Personal Projects

    This page contains all the projects that I do own my own.

    C-lestial

    A git repository that contains notes, C codes and demonstrations for numerical analysis. The aim is to provide comprehensive notes on the topic. For this, I read from the several textbooks and research articles.

    It also includes a library under the same name. I keep adding to the notes and the library whenever I read something.

    Notes

    This page contains some of my markdown notes or course submissions like term papers.
