Computational Astrophysics @ IIT Indore

CASIO
Computational astrophysics opens new windows in the way we perceive and study the heavens. This rapidly growing new discipline in astronomy combines modern computational methods and algorithms to simulate and analyze data so as to discover new phenomena, and to make predictions in astronomy, cosmology and planetary sciences.

CASIO covers research interests in a wide range of topics closely associated with Computational and theoretical aspects of Astrophysics. The current focus of the group is in two main areas :

Astrophysical Plasma processes relevant to AGN jets: To study dynamical evolution of jets from its launching to its feedback in the termination stage. Additionally, the group studies the complex interplay of particle acceleration and associated non-thermal polarised emission aimimg to develop synthetic observatories to bridge state-of-the-art simulations for predicting observational features with existing and up-coming observatories like ALMA, Lofar, SKA, TMT and CTA.
Space Plasma processes in the Sun-Earth environment: This group aims to provide an indigenous space weather modeling framework to reveal plasma features relating the Sun-Earth environment. We have created SWASTi, the Space Weather Adaptive Simulation Framework, to simulate solar wind, CMEs, and CIRs. The model has been verified against OMNI database data and showed computational efficiency and precise assessment. Such a framework is essential for assessment of upcoming Aditya L1 in-situ data from ASPEX, MAG and PAPA. Additionally, the group has developed MagPIE model to couple the magnetosphere-Ionosphere and thereby study the geoeffective of space weather drivers within the Sun-Earth environment. Such an indegenious and versatile framework would also be potentially useful tool for upcoming missions to study Venus (Shukrayaan) and DISHA (Ionosphere).

The group has acquired sponsored projects from CSIR EMR-II grant (2018-2021), Max Planck Partner group award (2019-2024), ISRO RESPOND Grant (2021-2024),
