Left: radio image of SNR G292.0+1.8 from the Rapid ASKAP Continuum Survey at 887.5 MHz , showing the full extent of the remnant. The color scale (square-root scale, in units of Jy beam^-1 is adjusted to enhance the visibility of the shell structure; consequently, the central PWN appears saturated. A zoom-in on the PWN is shown in the inset, where the square-root color scale ranges from 0.015 to 0.4 Jy beam^-1 and is optimized to highlight the internal PWN morphology. The contours in the inset are drawn at 0.07, 0.13, 0.18, and 0.3 Jy beam^-1 and are shown for reference to delineate internal structures. The yellow cross marks the position of the PSR J1124–5916. The synthesized beam is 25''×25'', and the rms noise level is 0.5 mJy beam^-1. Right: updated radio continuum spectrum of the PWN associated with PSR J1124-5916 within SNR G292.0+1.8. Green diamonds correspond to the new flux density measurements obtained in this work from radio surveys, whereas orange symbols represent values compiled from the literature (see Table 1). The solid line indicates the best fit to the weighted data, yielding a radio spectral index of α=-0.012 ± 0.010. The shaded gray and light blue bands denote the 1σ and 2σ statistical uncertainties in the best-fit α value, respectively.
