High-Resolution Imaging of the OH Megamaser Emission in IRAS 12032+1707 and IRAS 14070+0525

We present results from Very Long Baseline Array (VLBA) observations of the 1667 and 1665 MHz OH lines in two OH megamaser galaxies, IRAS 12032+1707 and IRAS 14070+0525. For IRAS 12032+1707 we also present Arecibo H I absorption data. Almost all OH emission previously detected by single-dish observa...

Zusammenfassung:We present results from Very Long Baseline Array (VLBA) observations of the 1667 and 1665 MHz OH lines in two OH megamaser galaxies, IRAS 12032+1707 and IRAS 14070+0525. For IRAS 12032+1707 we also present Arecibo H I absorption data. Almost all OH emission previously detected by single-dish observations has been recovered in IRAS 12032+1707 and is found on a compact scale of
