- It is not clear how the case for AGNs would differ in kind from the case
- for B-O galaxies. The Meta Model's supermassive stars have only small to
- modest redshift discrepancies prior to their supernova stage. Following
- supernova and collapse, their redshifts become quite large, as do their
- velocities. This is when the jets appear, just as in the Crab supernova
- remnant. Generally these high velocity quasars will be found outside their
- parent galaxy; but nothing prevents us from finding them inside, if we look
- soon enough after the supernova stage.
-
- Prior to the supernova, some central objects in AGNs and B-O galaxies
- will be supermassive stars: a part of the proposed extension of the H-R
- diagram to luminosities higher than the normal blue or red giant branches.
- AGNs nuclei may contain one or more supermassive variable stars, of the
- extended Mira type.
-
- My earlier statement was that AGN redshifts are not *reliable* distance
- indicators. There is lots of room for the redshift of a galaxy nucleus to
- differ from the average of the redshift of the approaching and receding
- portions of the disc. Composite spectra can average out a lot more than just
- the galaxy's rotation into a single redshift number. -|Tom|-
