A survey for H2O megamasers. III. Monitoring water vapor masers in active galaxies.
BRAATZ J.A., WILSON A.S., HENKEL C., GOUGH R. and SINCLAIR M.
Abstract (from CDS):
Our data include the first K-band science observations taken with the new 100 m Green Bank Telescope (GBT). The GBT data were taken during testing and commissioning of several new components and so are subject to some limitations; nevertheless, they are in most cases the most sensitive H2O spectra ever taken for each source and cover 800 MHz (≃10,800km.s–1) of bandwidth. Many new maser features are detected in these observations. Our data also include a tentative and a clear detection of the megamaser in NGC 6240 at epochs a year and a few months, respectively, prior to the detections reported by Hagiwara et al. and Nakai et al.
We also report a search for water vapor masers toward the nuclei of 58 highly inclined (i>80°), nearby galaxies. These sources were selected to investigate the tendency that H2O megamasers favor inclined galaxies. None were detected, confirming that megamasers are associated exclusively with active galactic nuclei.
