Scientists Confirm Halton Arp's Observations Again

"... it seems likely that redshift may not be due to an expanding Universe, and much of the speculations on the structure of the universe may require re-examination." -- Edwin P. Hubble, astronomer, 1947

"The present observations are used inductively to conclude that the compact objects [quasars] originate in the nuclei of large galaxies where the physical conditions approach singular values and that their excess redshifts are related to their young age as measured from this event." -- Halton C. Arp, astronomer, 1972

"There is nevertheless a nagging suspicion among some astronomers, that all may not be right with the deduction, from the redshift of galaxies via the Doppler effect, that the universe is expanding. The astronomer Halton Arp has found enigmatic and disturbing cases where a galaxy and a quasar, or a pair of galaxies, that are in apparent physical association have very different redshifts...." -- Carl E. Sagan, professor, 1985

"There's a large body of work going on, observational work, theoretical work, which is based on the assumption that quasars are at their cosmological distances. If it turns out seriously that we're right, then all that work is in vain. We don't know anything like as much as we think we do by saying that quasars are far away, and that's another huge problem for people to face up to." -- Geoffrey Burbidge, astrophysicist, 2000

Science Daily: Galaxy Encounter Fires Up Quasar.

ScienceDaily (June 25, 2010) — Using two of the world's largest telescopes, an international team of astronomers have found evidence of a collision between galaxies driving intense activity in a highly luminous quasar. The scientists, led by Montserrat Villar Martin of the Instituto de Astrofisica de Andalucía-CSIC in Spain, used the Very Large Telescope (VLT) in Chile and the Gran Telescopio Canarias (GTC) on La Palma in the Canary Islands, to study activity from the quasar SDSS J0123+00.

They publish their work in a paper in the journal Monthly Notices of the Royal Astronomical Society.

Several types of galaxies, known as active galaxies, emit enormous amounts of energy from their central region or nucleus, with the most luminous objects known as quasars.

Dear Jeffery:

The quasar host galaxy is at the same redshift, as measured from the absorption lines in the spectrum (z~0.4).

We know that the galaxy interacting with the quasar ~100 kpc in projection is at similar redshift as the quasar. We don't have a spectrum of it, but the narrow band image centered at the emission lines [OIII], once the adjacent continuum emission is subtracted, shines very brightly. Therefore, there is a lot of [OIII] line emission and this implies very *similar* redshift to that of the quasar.

This does not support Halton Arp's hypotheis (basically, there is no link with it). Based on the finding that some nearby galaxies are APPARENTLY physically connected by bridges and/or tidal tails with quasars located with much larger redshift, Arp proposed that the redshift cannot be of cosmological nature, i.e., it cannot be a consequence of the expansion of the Universe. If this was the case, a quasar and a galaxy with very different redshifts couldn't possibly be physically connected because the difference in redsfhit would imply a huge distance separation.

In our case, the quasar and the galaxy are at very similar redshift, so, no contradiction with the cosmological redshift at all.

If the quasar's redshift is z=.4, then it cannot possibly be one of the most distant objects in the universe.

Not this one, but others are. The point is that this discovery does nothing but weaken Arp's redshift.

Redshift remains an indicator of distance, not age.

Mr. Keown - You contradict yourself when you say that the z=4 redshift shows that the quasar is not far away and that that weakens Arps theory, which by the way is a confirmed peer reviewed fact. Do you read? See Burbridge and Arp, both of whom published papers throughout the 70's and 80's proving this.

can't the speeds of galaxies (and therefore their redshifts) change as a result of their interacting? And am I understanding this properly...that we current are gauging distance as a function of speed? How can we use speed as a reliable determination of distance, when speeds at the same distance can clearly vary based on the interactions of galaxies and other factors?

Thanks for sharing your artificial idea. This blog is really very useful. Windermere Intuitive Retreats And Workshops

Science cannot positively claim 90% of there observatory "knowledge" and findings are true. They think they HAVE an idea os much different than fact. OBSERVING can only deduce so much. I guarantee the "sizes of planets and stars and the distanceS " can't truly be accurate without a references.If Alpha Centari is 4 light years away, that means everything we are studying of it is 4 years old. ,But for us to travel that distance would be something like 16,000 miles per light year, so like 60,000 years to get there. And the thing that irritates me the most is how they seem to boast about knowing the number of stars in the "observable Universe is "anywhere" from 100-400 Billion Stars. They think a 300 billion gap difference is acceptable to publish as science......
