What the spectrum had confirmed was that this indeed was a low density, excited hydrogen filament connecting the two objects of vastly different redshift.
The point was, of course, that a line between quasar A and B passed directly between the nucleus of the galaxy and quasar D. On the face of it high redshift gas was indicated near the nucleus of the low redshift galaxy.Gravitational lensing theory had established that elliptical distributions of mass could lead to quadrupolar images of quasars with a 5th image, dim and non-magnified, near the center, often lost in the glare of the lensing mass. See for example. Elliptic Mass Distributions versus Elliptic Potentials in Gravitational Lenses. Kassiola, A. & Kovner, I : Astrophysical Journal v.417, p.450. http://adsabs.har...17..450K That was published in 1993, 5 years before Arp's book, so Arp was merely observing and confirming something, the 5th image, that had been predicted (not post-dicted) by Gravitational lensing theory.
if you extrapolate the luminosity required for an elliptical to have this M/L ratio it comes out MB = -25 mag.
M.B. Bell and D. McDiarmid of the National Research Council of Canada published an analysis of 46,400 (that's right -- forty six thousand!) quasar redshifts from the Sloan Digital Sky Survey.
And, btw, all of these people who take the time to announce on phys.org that they are filtering out arguments which they don't agree with, realize that those sorts of behaviors will of course happen in the event of ANY big upheaval in the space sciences - legitimate or not.In your case, they are ignoring a blowhard who leaves dozens of posts worth of gish-gallop/verbal diarrhea on a single article and who responds to challenges to his statement mainly going off on tangents. In short, they're not filtering out arguments, they are filtering out an asshole.
