Abstract: We report the first VLBI images of the water vapor maser emission in TXS 2226-184, one of the most distant known maser galaxies, at 102 Mpc. The emission is spread over a range of 350 km s−1 in velocity and over a projected distance of almost 5 pc, oriented at ≈ 60° with respect to a kpc-scale jet. The distribution of emission is consistent with a parsec-scale structure rotating around a central mass of ∼ 107Msolar.
