Scientist
Experimental X-ray Astronomy Group
Physical Research Laboratory
Since 2021, I have been working as a scientist at the Physical Research Laboratory, Ahmedabad, as part of the Experimental X-ray Astronomy group.
Here, I have had the pleasure of carrying out various activities at the crossroads of high-energy astrophysics, instrumentation and outreach, some of which are listed below:
Part of the Chandrayaan-2 Solar X-ray Monitor (XSM) and the Chandrayaan-3 Alpha Particle X-ray Spectrometer (APXS) teams
Outreach activities including night sky-watching sessions, demonstrations, open house exhibitions etc., on various occasions
Part of the multilayer-based, hard x-ray optics development program, along with handling tasks as part of XSM payload operations centre
Possibilities of detection of electromagnetic counterparts to GW events, their implications for the neutron star Equation-of-State with current and future EM + GW infrastructure.
Solar coronal heating, statistical studies of flare, Physics of acceleration within flares.
Microphysics of jets launched by active galactic nuclei, neutron stars, short gamma ray bursts and their interactions with the surrounding material
Developing infrastructure for astrophysical workloads with a focus on open, reproducible code implementing efficient, scalable and distributed algorithms
