Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope to study the most distant known quasar have found a tantalizing clue that may answer a longstanding cosmic chicken-and-egg question: which came first, supermassive black holes or giant galaxies?




However, the new VLA observations of a quasar and its host galaxy seen as they were when the Universe was less than a billion years old indicate that the young galaxy has a supermassive black hole but no massive bulge of stars.

Ah, so the smbh came first.

But only after the galaxy. :^o

Here (http://arxiv.org/abs/astro-ph/0410229) is the science paper. They do not say that stars are not present, but only that the stellar bulge of the size/mass expected from relation established for lower redshift quasars isn't present. This interesting relationship established in lower redshift quasars and active galactic nuclei in general is that the mass of the smbh scales in proportion to the stellar spheroid mass...

Would it be safe to say that the article assumes the BBT is correct and that redshift is doppler? :-?

By the same token, what does this new discovery mean for the SS theory and others, is it a nail in the coffin or more conclusive proof? 8-[
