High-resolution Imaging of the OH Megamaser Emission in IRAS12032+1707 and IRAS14070+0525
Y. M. Pihlstrom, W. A. Baan, J. Darling +1
We present results from VLBA observations of the 1667 and 1665 MHz OH lines in the two OH megamaser galaxies IRAS12032+1707 and IRAS14070+0525. For IRAS12032+1707 we also present A…

VLBI imaging of OH absorption: The puzzle of the nuclear region of NGC 3079
Y. Hagiwara, H. -R. Kloeckner, W. Baan
Broad hydroxyl (OH) absorption-lines in the 1667 MHz and 1665 MHz transition towards the central region of NGC 3079 have been observed at high resolution with the European VLBI Net…

Investigation of the obscuring circumnuclear torus in the active galaxy Mrk231
Hans-Rainer Kl"ockner, Willem A. Baan, Michael A. Garrett
Here we report on observations of powerful hydroxyl (OH) line emissions that trace the obscuring material within the circumnuclear environment of the galaxy Markarian 231. The hydr…
