Quasars are blue shifted Galaxies


Authors Basu, D.; Haque-Copilah, S. & Valtonen, M., in their paper titled “Blueshifted Quasars Associated with Nearby Galaxies? said in their abstract “…may appear quasar-like with a blueshifted spectrum due to the Doppler effect. But quasar spectra are as a rule interpreted as having been redshifted even when there is an equally good or better case for a blueshifted spectrum. Here we study the quasars which are apparently associated with galaxies.” In International Journal of Modern Physics A, Volume 15, Issue 07, pp. 1057-1077 (2000), with Bibliographic Code: 2000IJMPA..15.1057B. These sentences indicate that quasars are Blueshifted Galaxies due to Doppler effect, but as a rule they are interpreted as redshifted. I don’t know what the rule was….

          In another recent example from 2012, the authors, H Meusinger, P Schalldach, R-D Scholz, A in der Au, M Newholm, A de Hoon, and B Kaminsky in their paper, “Unusual quasars from the Sloan Digital Sky Survey selected by means of Kohonen self-organising maps” in Journal  Astronomy & Astrophysics manuscript no. meusinger˙v2 ,ESO 2012 April 23, 2012 , arXiv: 1203.0215v2; have shown many graphs, in Fig 3 & 5 of lower wave lengths than the visual spectrum. They were trying to estimate the proper motions of the Quasars in fig 4. All these show the higher frequency bands of quasars and they are Blue shifted. Many more examples can be shown that quasars are blue shifted Galaxies.
