Fig. 3.


First panel of each row: Chandra X-ray image with VLA radio contours overlaid in red. Dashed white lines indicate previously identified X-ray cavity positions. Black contours represent the distribution of the cold molecular gas. Second panel of each row: optical image from HST overlaid with black contours representing the distribution of the cold molecular gas. We show Hα emission distribution as orange contours. The first two panels cover the same area. Panels 3−5 from the left along each row: the three panels are, in order from left to right, the first-, second-, and third-moment maps of the ≥3σ CO emission (i.e., intensity map, integrated intensity velocity map, and velocity dispersion map). All source names are indicated at the top right in the first panel of each row and the contents of each image is given in the upper right of each panel. In the moment-zero map, the red contours represent the radio emission from VLA observations from 1.58 GHz for Centaurus, 1.46 GHz for Abell S1101, 1.46 GHz for PKS 0745−191, 1.45 GHz for Abell 262 and 4.89 GHz for Hydra-A, 4.86 GHz for Abell 2597, 4.91 GHz for M 87, 4.19 GHz for Abell 1795, 4.89 GHz for 2A 0335+096, and 1.46 GHz for PKS 0745−191. The white cross indicates the position of the mm-continuum source. The velocity dispersion sometimes appears high because of the presence of multiple velocity components; each component has a small velocity dispersion.
