Panel a: X-ray emission towards PSR J1826−1256 in the 1–7 keV energy band. Cyan contours correspond to 9.5, 10.5, and 12.0 counts pixel⁻¹. The position of the pulsar is indicated with a plus sign. Green contours trace the TeV emission from HESS J1826−130 at levels of (1.5, 1.8, and 2.1) × 10⁻¹³ ph cm⁻² s⁻¹. Panel b: a brightness profile along the PWN (solid line) and the adjacent background (dashed line). The rectangular box in the inset image indicates the regions from which the radial profile was extracted.
