Abstract

Mrk 273 and Mrk 231 are ultra-luminous IR galaxies which show signs of merger activity. Their radio continuum, HI and OH maser emission has been imaged on scales of tens of parsec using MERLIN. Mrk 273 and Mrk 231 are classed as Sy 2 and Sy 1 respectively. The distribution of material and velocity gradients shown by OH masers and HI absorption are consistent with material in a rotating disk or ring. In Mrk 273 the axis is at greater than 45 degrees to the line of sight; in Mrk 231 it is at less than 45 degrees to the line of sight. The amount of mass enclosed is estimated, and its distribution is inferred from irregularities in the masers and comparison with the HI and radio continuum data.
