Fermi-LAT TS map of the region surrounding PSR J1124–5916 for energies above 1 GeV in Galactic coordinates during the OFF-pulse phase interval. All sources in the 4FGL-DR3 catalog were included, except the pulsar source 4FGL J1124.7–5915, which was removed from the model. The color bar indicates the TS value range. The white star marks the position of PSR J1124-5916. The dash-dot black circle represents the 1σ error radius for the best-fit position obtained in the off-pulse phase interval analysis, while the dashed black circle indicates the 95% confidence level upper limit on the source extension. Light blue contours show radio data from the Molonglo Observatory Synthesis Telescope (MOST), highlighting the extent of the radio PWN; the green circle corresponds to the X-ray PWN extension detected by Chandra (Hughes et al. 2003), and the red circle indicates the SNR G292.0+1.8 extension.
