QUASAR REDSHIFT CLUSTERS AND (EVEN WORSE) MULTIPLE REDSHIFTS

At the XIIIth Krakow Summer School of Cosmology, September 7-12, 1992, many of the world's top cosmologists experienced the disorientation that accompanies both earthquakes and shifting paradigms. Two of many cosmoseisms felt during the meeting in Poland are recorded below:

"Halton Arp, Max-Planck Institute for Astrophysics, spoke about his "Variable Mass" cosmology. He pointed out the need for cosmologies to explain why quasar redshifts cluster near 0.3, 0.6..., with the grouping just below z = 1.2 dominating all others; and why certain classes of stars have significant excess redshifts. He also pointed out the inconsistency that local galaxy groups seem to have velocity dispersions of less than 100 km/s, while distant groups seem to have members with dispersions up to 1000 km/s.

"Jack Sulentic spoke about multiple redshifts seen in some quasars and AGNs. Line profiles come in all types; symmetric, double-peaked, and asymmetric. Relative shifts are both toward the red and the blue. Arguments against an accretion disk/black-hole model were reviewed. Apparently a non-Doppler redshift-blueshift mechanism is needed. For example, one broad line (in 1404 + 28) shifts back and forth by 1000 km/s relative to another narrow H-line, with an average offset of 2000 km/s. These shifts correlate perfectly with intensity."

Less technically speaking, the longheld belief that redshifts are solely due to the Doppler effect is receding along with the expanding universe!

Quotes

  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
