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…
First Robust Detection of Linear Polarization from Metric Solar Emissions: Challenging Established Paradigms
Soham Dey, Devojyoti Kansabanik, Divya Oberoi +1
Polarimetric radio observations of the Sun can provide rich information about emission mechanisms and the propagation medium. For the past five decades, solar polarimetric studies…
Observation and Modeling of Small Spatial Structures of Solar Radio Noise Storms using the uGMRT
Surajit Mondal, Peijin Zhang, Devojyoti Kansabanik +2
One of the most commonly observed solar radio sources in the metric and decametric wavelengths is the solar noise storm. These are generally associated with active regions and are…
A Formalism for Calibrating the Instrumental Polarization of Radio Interferometric Arrays at Meter Wavelengths using Unpolarized Sky: A Demonstration using the MWA Observations
Devojyoti Kansabanik, Angelos Vourlidas, Soham Dey +2
Calibration of instrumental polarization is critical for measuring polarized radio emissions from astrophysical sources to extract the magnetic field information in astrophysical,…
New Insights into Type-I Solar Noise Storms from High Angular Resolution Spectroscopic Imaging with the Upgraded Giant Metrewave Radio Telescope
Surajit Mondal, Devojyoti Kansabanik, Divya Oberoi +1
Type-I solar noise storms are perhaps the most commonly observed active radio emissions from the Sun at meter-wavelengths. Noise storms have a long-lived and wideband continuum bac…
