“ Exploring solar radio emissions through spectro-polarimetric snapshot imaging”
>
Abstract: The Sun is a dynamic radio-source, emitting across a wide
range of intensities and polarization states – from the quiet Sun and  faint coronal mass ejections (CMSs) to intense solar radio bursts.
Traditionally, most solar radio studies have relied on dynamic spectra,
which cannot provide information about source morphology, multiplicity,
and spatial evolution. To fully understand the spatial and temporal
complexity of these emissions, spectroscopic snapshot imaging is
essential.
In this talk, I will present the development and implementation of
automated solar observation and imaging pipelines designed to address
this need. I will focus on the real-time triggering mechanism developed
for MWA and the recent advances in the LOFAR imaging pipeline, which now
delivers images with 1-2 orders of magnitude improvement in dynamic
range and fidelity. While the full-Stokes (polarization) capability is
still under development for LOFAR, the progress thus is very promising.
