• W3100686738 abstract "We present single-dish monitoring of the spectra of 13 extragalactic water megamasers taken over a period of 9 years and a single epoch of sensitive spectra for seven others. The primary motivation is a search for drifting line velocities analogous to those of the systemic features in NGC 4258, which are known to result from centripetal acceleration of gas in an edge-on, subparsec molecular disk. We detect a velocity drift analogous to that in NGC 4258 in only one source, NGC 2639. Another, the maser source in NGC 1052, exhibits erratic changes in its broad maser profile over time. Narrow maser features in all of the other disk galaxies discussed here either remain essentially constant in velocity over the monitoring period or are sufficiently weak or variable in intensity that individual features cannot be traced reliably from one epoch to the next. In the context of a circumnuclear, molecular disk model, our results suggest that either (a) the maser lines seen are systemic features subject to a much smaller acceleration than present in NGC 4258, presumably because the gas is farther from the nuclear black hole, or (b) we are detecting satellite lines for which the acceleration is in the plane of the sky." @default.
