Abstract (from CDS):

We report on the discovery of H I in absorption toward the gigamaser galaxy TXS 2226-184 using the Very Large Array. The absorption appears to consist of two components–one with a width of 125 km.s–1 and one broader (420 km.s–1) – both toward the compact radio source in the nucleus of the galaxy. Based on these large velocity widths, we suggest that the H I absorption is produced in the central parsecs of the galaxy, on a scale similar to that which gives rise to the water maser emission. This brings to eight the number of galaxies known to exhibit both water masers and H I absorption. We explore the relationship between these two phenomena and present a physically motivated (but unfruitful) search for water maser emission in five radio galaxies known to exhibit strong H I absorption.
