Chandra images of the core (≈200 × 200 kpc, or 9.6 × 9.6 arcmin) of the Perseus Cluster divided by the spherically symmetric β-model in the 0.5–4 keV (top left) and 4–8 keV (top right) bands. Point sources and the central AGN are excised. Arrows point to the prominent features identified in previous studies. Dashed regions indicate selected regions with a shock, a bubble and a spiral. They are enlarged in the middle and bottom panels. The colour scales of the image pairs are the same. For display purposes, all images are lightly smoothed with a 2 arcsec Gaussian.
