Imaging and location of FRB 20201124A from radio to X-rays. Left panel: VLA image at 22 GHz presented in this work (in colors), with contours indicating the 3, 4, and 5 sigma significance levels. The full width at half maximum is reported in the lower-left corner; shown are the SDSS host galaxy centroid and half-light radius (red) and the CXO extraction region (white), centered on the EVN FRB position (yellow cross). Right panel: e-MERLIN image at 5 GHz of the persistent radio source region, showing no detection. Contours are from the VLA image at 22 GHz. The cross indicates the location of FRB 20201124A from EVN observations (Marcote et al. 2021). The full width at half maximum is reported in the lower-left corner. The inset shows the EVN image from our campaign (25 × 25 mas) with no detection at the FRB location, also at 5 GHz.
