A high-frequency type II radio burst associated with an X2.3 class flare
Divya Paliwal, Anshu Kumari, Vishwa Vijay Singh +3
Radio observations provide a powerful diagnostic of the solar corona, enabling investigations of dynamic phenomena associated with solar flares, coronal mass ejections (CMEs), and…
Multi-lane type II radio bursts: Insights into shock propagation in the corona
Nadiya K., Divya Paliwal, Anshu Kumari
Type II solar radio bursts are considered as the signatures of the coronal shocks. These bursts are generated from plasma waves excited by magnetohydrodynamic (MHD) shocks, and the…
RAISE: A Low-Frequency Space-Based Payload for Solar Radio and RFI Measurements on the SMiLE Mission
Sangeetha A, Harsha Avinash Tanti, Abhirup Datta +2
We present the Radio-wave Apparatus for Investigating Solar & Earth interference (RAISE), a compact low-frequency radio payload proposed for hosting on the SMiLE mission. Operating…
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…
Radio Wave Propagation as a Probe of the Solar Corona and Solar Wind
K. Sasikumar Raja, Prasad Subramanian, Susanta Kumar Bisoi +3
Radio waves propagating through an inhomogeneous, turbulent medium such as the solar corona and solar wind become distorted, causing the initially plane wavefronts becomes corrugat…
Microwave Polar Brightening and Its Connection to Polar Coronal Holes
Rohan Bose, Anshu Kumari, Vaibhav Pant +3
Polar brightening (PB) observed at microwave frequencies serves as an important probe to study the thermal and magnetic properties in the Sun's polar regions. Building on earlier s…
Radio Signature of Higher Atmospheric Meridional Flow and Implications for Magnetic Trees in the Sun
Srinjana Routh, Anshu Kumari, Rohan Bose +4
The coupling between plasma flows and magnetic fields in the solar atmosphere governs the transport of angular momentum and the redistribution of magnetic flux, yet its manifestati…
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…
Probing the Solar Corona and the Solar Wind Using Angular Broadening Observations with the SKA
Peijin Zhang, John Morgan, Divya Oberoi +9
Angular broadening observations of compact radio sources provide a powerful method for probing the solar corona and solar wind. Such observations enable studies of the phase struct…
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…
Solar Radio Spectro-polarimetry (50-500 MHz) : Design and Development of Cross-Polarized Log-Periodic Dipole antenna and configuration of receiver system
Anshu Kumari, G. V. S. Gireesh, C. Kathiravan +2
A radio spectro-polarimeter was developed at the Gauribidanur radio observatory to study the characteristics of the polarized radio waves that are emitted by the impetuous solar co…
