Role of SKA in Advancing Remote Measurements of Magnetic Fields of Solar Coronal Mass Ejections
Devojyoti Kansabanik, Surajit Mondal, Shaheda Begum Shaik +13
Coronal Mass Ejections (CMEs) are large expulsions of magnetized plasma from the Sun into interplanetary space and are the primary drivers of extreme space weather variations. The…
Coronal Magnetography using Spectropolarimetry with SKA Telescopes
Deepan Patra, Puja Majee, Soham Dey +6
The solar coronal magnetic field drives nearly every aspect of solar phenomena and activity -- from flares, coronal mass ejections, and solar wind that governs space weather to the…
State-of-the-art Observation, Calibration, and Imaging Framework for Solar and Heliospheric Sciences with SKA
Divya Oberoi, Devojyoti Kansabanik, Soham Dey +6
The Sun is a surprisingly difficult radio source to observe and image, even with the SKA. It is multiple orders brighter than the typical radio sources, which sensitive radio teles…
Solar energetic particles and their association with radio emissions
Diana E. Morosan, Anshu Kumari, Immanuel Jebaraj +6
Energetic particle populations are ubiquitous throughout the Universe. In our solar system, the most prominent sources of energetic particles are solar flares or collisionless shoc…
Solar Radio Bursts in the metric to kilometric range
Anshu Kumari, Mugundhan V., Diana E. Morosan +6
Solar radio bursts (SRBs) are intense emissions observed in radio wavelengths most frequently during solar transients, such as coronal mass ejections (CMEs) and flares. SRBs are di…
Long-term monitoring of repeating FRB 20220912A with the uGMRT at low radio frequencies
Ajay Kumar, Yogesh Maan, Banshi Lal +4
Some repeating FRBs exhibit occasional extreme repetition rates, but very few show a sustained high activity level. One such hyperactive repeater is FRB 20220912A, which was discov…
On Using Gradient Dynamic Spectra (GraDS) to Study Type-II Solar Radio Bursts
Puja Majee, Devojyoti Kansabanik, Divya Oberoi
Solar type-II radio bursts are coherent plasma emissions arising from magnetohydrodynamic shocks produced by either coronal mass ejections (CMEs) or flares. Type-II bursts sometime…
Space Weather Research using Spectropolarimetric Radio Imaging Combined With Aditya-L1 and PUNCH Missions
Devojyoti Kansabanik, Surajit Mondal, Divya Oberoi +1
Low-frequency radio observations have been expected to serve as a powerful tool for Space Weather (SW) observations for decades. Radio observations are sensitive to a wide range of…
