Left: merged Chandra exposure-corrected 0.5–7 keV ACIS-I array image of the extended emission around PSR J1809−2332 (observation IDs 739, 12546), adaptively smoothed (0.5–15 pixel Gaussian kernels, 10 ⁻⁶ erg cm ⁻² s ⁻¹ flux minimum). A possible bow shock and trail are seen extending northwest from the pulsar. Point sources used in frame matching are shown in green, with the pulsar position marked with a black plus symbol. The white ellipse denotes the 1σ error ellipse for the extrapolated pulsar position some 10 kyr in the past, while the white arrow points to the proposed explosion site for SNR G7.5−1.7. These two directions agree within 1σ. Right: merged adaptively smoothed (0.5–15 pixel Gaussian kernels, 3 count minimum) 0.5–7 keV image of the 100'' surrounding the pulsar. Both panels are displayed with a logarithmic stretch.
