Scientific paper

Observations of the double-nucleus galaxy Markarian 266 are presented which reveal a complex system consisting of extranuclear optical knots and multiple radio continuum components. The observations indicate that Mrk 266 is a close pair of interacting galaxies. Radio synthesis images show the presence of a nonthermal radio source located between the nuclei of Mrk 266, in addition to emission associated with the active nuclei and extended 20 cm emission located about 20 arcsec to the north of the nuclei. Radio synthesis data at 20 cm, 6 cm, and 2 cm are used to produce spectral indices for the three components, and a high-resolution 6 cm synthesis image reveals substructure in the central and SW radio components. Possible interpretations of these data are discusssed, and it is concluded that the enhanced radio emission between the nuclei of Mrk 266 can be consistently interpreted in terms of a particle acceleration mechanism induced by a collision or ongoing merger between two galaxies.
