LOFAR Non-detections of SN 2023ixf in its First Year Post-explosion

Timmerman, R.; Arias, M.; Botteon, A.

Abstract

We used the LOw Frequency ARray (LOFAR) telescope to monitor SN 2023ixf, a core-collapse supernova in M101, between 8 and 368 days post-explosion. We report non-detections down to ~ 80 μJy sensitivity at 144 MHz. Our non-detections are consistent with published radio observations at higher frequencies. At the time, we are not able to constrain the properties of low-frequency absorption due to the progenitor star’s circumstellar medium via these LOFAR observations.
