Imaging-spectroscopy of a band-split type II solar radio burst with the Murchison Widefield Array
Shilpi Bhunia, Eoin P. Carley, Divya Oberoi +1
Type II solar radio bursts are caused by magnetohydrodynamics (MHD) shocks driven by solar eruptive events such as Coronal Mass Ejections (CMEs). Often both fundamental and harmoni…
Study of radio transients from the quiet Sun during an extremely quiet time
Surajit Mondal, Divya Oberoi, Ayan Biswas
In this work we study a class of recently discovered metrewave solar transients referred to as Weak Impulsive Narrowband Quiet Sun Emission \citep[WINQSEs,][]{mondal2020}. Their st…
Preparing for Solar and Heliospheric Science with the SKAO: An Indian Perspective
Divya Oberoi, Susanta Kumar Bisoi, K. Sasikumar Raja +4
The Square Kilometre Array Observatory (SKAO) is perhaps the most ambitious radio telescope envisaged yet. It will enable unprecedented studies of the Sun, the corona and the helio…
Plans for building a prototype SKA regional centre in India
Yogesh Wadadekar, Dipankar Bhattacharya, Abhirup Datta +2
In order to deliver the full science potential of the Square Kilometer Array (SKA) telescope, several SKA Regional Centres (SRCs) will be required to be constructed in different SK…
Tackling the Unique Challenges of Low-frequency Solar Polarimetry with the Square Kilometre Array Low Precursor: Pipeline Implementation
Devojyoti Kansabanik, Apurba Bera, Divya Oberoi +1
The dynamics and the structure of the solar corona are determined by its magnetic field. Measuring coronal magnetic fields is, however, extremely hard. The polarization of low-freq…
Detection of weak ubiquitous impulsive nonthermal emissions from the solar corona
Rohit Sharma, Divya Oberoi, Marina Battaglia +1
A ubiquitous presence of weak energy releases is one of the most promising hypotheses to explain coronal heating, referred to as the nanoflare hypothesis. The accelerated electrons…
