Inexpertly, Seyfert 2 galaxies are Seyfert 1 galaxies, but viewed "edge on" instead of "face on". However, megamasers are not observed, from "face on" Seyfert 1 galaxies. Since masing amplification derives from the optical depth, along the sightline to earth, of excited "pumped" molecules, perhaps the accretion tori of Seyfert galaxies are flat and wide, resembling a large washer, for a bolt or screw? Low flat wide accretion tori would have considerably more optical depth "edge on" than "face on", since the sightlines through the masing medium would be allot longer. So, perhaps the association of megamasers only with "edge on" Seyferts suggests something of the structure of their SMBH accretion disks? Moreover, the SMBH in "edge on" Seyferts resides directly behind (half of) the masing medium, and so might be a source of the "triggering" radio emissions? 66.235.38.214 ( talk) 04:34, 26 December 2012 (UTC)
