![]() X-ray and
(E)UV observations of a large X-class solar flare. Looptop (LT) and footpoint (FP) sources are observed in hard X-ray energies
and corresponding X-ray spectrum (Joshi et al. 2013, ApJ) .
Research Interests
My research interest encompasses understanding the transient activity of our star, the Sun, and its influence on
interplanetary medium and near-Earth environment. An important aspect of my research is to explore the physics of basic plasma
processes which are believed to occur during the onset and evolution of the solar eruptive phenomena. We focus on the following topics:
Participation in ISRO's Space Programs for Solar Studies
Solar Radio Observations @ Udaipur
Since October 2018, a CALLISTO Solar Radio Spectrometer is operational at USO-PRL. The system has been indigenously developed and installed in collaboration
with ETH Zurich, Switzerland. The CALLISTO — Compound Astronomical Low cost Low frequency Instrument for Spectroscopy and
Transportable Observatory — natively operates between 45 and 870 MHz and is capable of observing the solar eruptive events on
real-time basis. The details of instrument and data (quick look and raw files)
are available in Udaipur CALLISTO website.
Since January 2024, an LWA based spectrometer has been operation for observations of solar radio emission in the frequency band of 20-80 MHz. Research Supervision
