A combined GMRT/CLFST image of IC443 at 150 MHz

TL;DR

This paper presents a composite radio image of the supernova remnant IC443 at 150 MHz, combining GMRT and CLFST data to capture structures from large arcminutes to small arcseconds.

Contribution

The study introduces a method to combine data from GMRT and CLFST to image IC443 across all relevant angular scales at low radio frequencies.

Findings

Successful creation of a multi-scale image of IC443

Enhanced understanding of IC443's fine structure

Demonstration of data combination technique for multi-instrument imaging

Abstract

IC443 is a relatively large Galactic (~45 arcmin) SNR with a high radio surface brightness. It has fine scale structure down to arcsec scales, and so is difficult to image on all angular scales with a single instrument. Here observations of IC443 at 151 MHz made with both the GMRT and the CLFST are combined to give a composite image of IC443 on all scales from >45 arcmin down to ~20 arcsec.
