First systematic study reporting the changes in eclipse cut-off frequency for pulsar J1544+4937
Sangita Kumari, Bhaswati Bhattacharyya, Rahul Sharan +3
We present results from a long-term monitoring of frequency dependent eclipses of the radio emission from PSR J1544+4937 which is a ``black widow spider'' millisecond pulsar (MSP)…
Deciphering Radio Emission from Solar Coronal Mass Ejections using High-fidelity Spectropolarimetric Radio Imaging
Devojyoti Kansabanik
Coronal mass ejections (CMEs) are large-scale expulsions of plasma and magnetic fields from the Sun into the heliosphere and are the most important driver of space weather. The geo…
A detailed study of the polarisation convention of the Giant Metrewave Radio Telescope
Poonam Chandra, S. Suresh Kumar, Sanjay Kudale +5
Our work aims to investigate the polarisation convention of the Giant Metrewave Radio Telescope (GMRT) radio telescope and understand whether the telescope follows the standard IAU…
Spectroscopic Imaging of the Sun with MeerKAT: Opening a New Frontier in Solar Physics
Devojyoti Kansabanik, Surajit Mondal, Divya Oberoi +7
Solar radio emissions provide several unique diagnostics to estimate different physical parameters of the solar corona, which are otherwise simply inaccessible. However, imaging th…
Characterizing the Spectral Structure of Weak Impulsive Narrowband Quiet Sun Emissions
Surajit Mondal, Divya Oberoi, Ayan Biswas +1
Weak Impulsive Narrowband Quiet Sun Emissions (WINQSEs) are a newly discovered class of radio emission from the solar corona. These emissions are characterized by their extremely i…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
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…
Deciphering Faint Gyrosynchrotron Emission from Coronal Mass Ejection using Spectro-polarimetric Radio Imaging
Devojyoti Kansabanik, Surajit Mondal, Divya Oberoi
Measurements of the plasma parameters of coronal mass ejections (CMEs), particularly the magnetic field and nonthermal electron population entrained in the CME plasma, are crucial…
