We present results from optical , X-ray and radio observations of two X-ray bright ( L _ { X } \sim 10 ^ { 45 } erg s ^ { -1 } ) galaxy clusters .
Abell 1451 is at redshift z = 0.1989 and has line-of-sight velocity dispersion \sigma _ { v } = 1330 km s ^ { -1 } as measured from 57 cluster galaxies .
It has regular X-ray emission without signs of substructure , a Gaussian velocity distribution , lack of a cooling flow region and significant deviations from the observed scaling laws between luminosity , temperature and velocity dispersion , indicating a possible merging shock .
There is only one spectroscopically confirmed cluster radio galaxy , which is close to the X-ray peak . 1RXS J131423.6 - 251521 ( for short RXJ1314 - 25 ) has z = 0.2474 and \sigma _ { v } = 1100 km s ^ { -1 } from 37 galaxies .
There are two distinct galaxy groups with a projected separation of \approx 700 kpc .
The velocity histogram is bi-modal with a redshift-space separation of \sim 1700 km s ^ { -1 } , and the X-ray emission is double peaked .
Although there are no spectroscopically confirmed cluster radio galaxies , we have identified a plausible relic source candidate .
