We present an analysis of a highly asymmetric cluster merger from a Chandra observation of Abell 85 .
The merger shows significant disruption of the less massive subcluster from ram pressure effects .
Nevertheless , a cold core , coincident with the cD galaxy , is observed to persist in the subcluster .
We derive dynamical information from the motion of the cold core through the main cluster ’ s ICM .
Multiple derivations of the velocity of the core suggest a Mach number of \mathcal { M } \approx 1.4 , or v \sim 2150 km s ^ { -1 } , though with substantial uncertainty .
We construct a consistent kinematic model for the merger based on this dynamical analysis .
As has been found for other such “ cold fronts , ” conduction appears to be suppressed across the front .
Thermal conduction may be suppressed by a magnetic field with a significant component perpendicular to the subcluster ’ s direction of motion .
The effect of the merger interaction in creating and shaping the observed radio sources is also discussed .
It appears most likely that the radio source is due to distorted and detached lobes from the subcluster cD galaxy , rather than being a radio halo .
