Zoomed-in views of the >1 GeV Fermi-LAT total dataset TS maps in a 2°×2° region centered on 4FGL J1124.7–5915. Left: residual TS map with all 4FGL-DR3 sources except PSR J1124-5916 / 4FGL J1124.7–5915 and the newly detected source. The map highlights the pulsar emission. Middle: residual TS map with all 4FGL-DR3 sources, including 4FGL J1124.7-5915, with best-fit parameters derived from the likelihood analysis. The map highlights the excess emission associated with the newly detected source corresponding to the PWN hosted in SNR G292.0+1.8. The dash-dotted black circle indicates the best-fit position of the new source, with the radius corresponding to the 68% confidence positional uncertainty. The 95% confidence upper limit on the source extension is shown by a larger dash-dotted black circle. The position of PSR J1124–5916 / 4FGL J1124.7–5915 is marked with a white star. Radio contours are overlaid in cyan; 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. Right: residual TS map for the complete source model, including all 4FGL-DR3 sources, PSR J1124–5916/4FGL J1124.7–5915, and the newly detected source, demonstrating that the emission is well accounted for.
