Scientific paper

Analysis of a short Chandra observation of the cooling core cluster Abell 262 reveals several features that warrant further study. In the cluster center, both a bubble and tunnel are found coincident with radio emission from the central AGN. A possible ghost bubble is identified with low-frequency radio emission. A ripple or shock front feature has been revealed and may be due to a previous outburst from the radio source. We propose to study this ripple/front in detail, detect hot gas within the bubble and tunnel, search for additional ghost bubbles, and measure the cooling rate of the X-ray gas found in knot-like features in the cluster center that also emit optical line emission.
