Faraday Complexity and Depolarisation in a High-Rotation-Measure Radio Galaxy from the Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) DR2
Debajyoti Mondal, Abhik Ghosh, Dipanjan Banerjee
We present a broadband spectro-polarimetric analysis of the extragalactic radio source \texttt{RACS\_0900-28\_7036} using SPICE-RACS DR2 observations with the Australian Square Kil…

Studying Ionospheric Phase Structure Functions Using Wide-Band uGMRT (Band-4) Interferometric Data
Dipanjan Banerjee, Abhik Ghosh, Sushanta K. Mondal +1
Interferometric observations of the low-frequency radio sky (< 1 GHz) are largely limited by systematic effects introduced by the ionosphere. Here, we analyse a ten-hour nighttime…

Probing Equatorial Ionospheric TEC at Sub-GHz Frequencies with Wide-Band (B4) uGMRT Interferometric Data
Dipanjan Banerjee, Abhik Ghosh, Sushanta K Mondal +1
Phase stability at low radio frequencies is severely impacted by ionospheric propagation delays. Radio interferometers such as the Giant Metrewave Radio Telescope (GMRT) are capabl…
