Extended Data Fig. 1: Field of ASKAP J1832–0911.
From: Detection of X-ray emission from a bright long-period radio transient
Panel (a) shows a composite of radio (MeerKAT 816 MHz, red), X-ray (Chandra 1–10 keV, green), and infrared (WISE 12 μm, blue) emission of the field of ASKAP J1832–0911. The Fermi 95% positional error ellipse around 4FGL J1832.9-0913 is shown in cyan dashed line. The supernovae remnant SNR G22.7–0.2 is highlighted in the yellow dotted line. Panel (b) shows MeerKAT total intensity contours at 30, 40, and 50 mJy levels overlaid on the Chandra detection image on 2024 February 14. Panel (c) and (d) show the deepest near-infrared images of ASKAP J1832–0911 at J- and Ks-band, respectively. Red circles show 50 times the systematic uncertainty of the source position (~5 mas).
