Abstract

Astronomy & Astrophysics Physical Sciences Science & Technology
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 approximate to 60 degrees with respect to a kpc-scale jet. The distribution of emission is consistent with a parsec-scale structure rotating around a central mass of similar to 10(7) M-circle dot.
