"Black Holes Create their Host Galaxies" --An Odd Quasar Provides the Clues

The answer may have been found to the question of whether a galaxy or its black hole comes first -one of the most debated subjects in astrophysics today. A recent study suggests that supermassive black holes can trigger the formation of stars, thus 'building' their own host galaxies. 

This 2011 finding could also explain why galaxies hosting larger black holes have more stars. To reach such an extraordinary conclusion, the team of astronomers conducted extensive observations of a peculiar object, the quasar HE0450-2958, also called the "naked quasar" and the "quasar without a home," because it the only one for which a host galaxy has not yet been detected.
Until recently, it was speculated that the quasar's host galaxy was hidden behind large amounts of dust, and so the astronomers used a mid-infrared instrument on ESO's Very Large Telescope for the observations . At such wavelengths, dust clouds shine very brightly, and are readily detected.

"Observing at these wavelengths would allow us to trace dust that might hide the host galaxy," says Knud Jahnke, who led the observations performed at the VLT. "However, we did not find any. Instead we discovered that an apparently unrelated galaxy in the quasar's immediate neighborhood is producing stars at a frantic rate."

These observations have provided a surprising new take on the system. While no trace of stars is revealed around the black hole, its companion galaxy is extremely rich in bright and very young stars. It is forming stars at a rate equivalent to about 350 Suns per year, one hundred times more than rates for typical galaxies in the local Universe.

Earlier observations had shown that the companion galaxy is, in fact, under fire: the quasar is spewing a jet of highly energetic particles towards its companion, accompanied by a stream of fast-moving gas. The injection of matter and energy into the galaxy indicates that the quasar itself might be inducing the formation of stars and thereby creating its own host galaxy; in such a scenario, galaxies would have evolved from clouds of gas hit by the energetic jets emerging from quasars.

"The two objects are bound to merge in the future: the quasar is moving at a speed of only a few tens of thousands of km/h with respect to the companion galaxy and their separation is only about 22 000 light-years," says Elbaz. "Although the quasar is still 'naked', it will eventually be 'dressed' when it merges with its star-rich companion. It will then finally reside inside a host galaxy like all other quasars."

The team identified black hole jets as a possible driver of galaxy formation, which may also represent the long-sought missing link to understanding why the mass of black holes is larger in galaxies that contain more stars. "A natural extension of our work is to search for similar objects in other systems," says Jahnke.

The electromagnetic trap (black hole) may have been centered on the near by galaxy and been 'released' by the diminishment of its EM field. This diminishment allowed the pressure holding gas inside to drop, allowing gas to flood out. This gas is the source of the energy the formerly red stars are using to burn hot and fast.
Is this an example of a time varying field? As for the stream of energy, one might take note of the streams of energy outgassing from the Milky Way. Is this evidence of diminishment of pressurized EM fields?

I had two basic theories.
a. Having that much physical mass in one area would somehow lead to the creation of the sbh.
b. It is in fact the sbh that creates the galaxy around it. (and probably all visible matter. i.e. stars and planets
B seems more likely than A, I can’t be bother explaining why here just now.
I ended up googling “do supermassive black holes create galaxies” and ended up here.

Do supermassive black holes create galaxies?
I think yes!
I was just thinking about why there would be a supermassive black hole at the centre of the galaxy (and apparently at the centre of all galaxies), and I figured that I was possibly asking the question the wrong way… perhaps it should be, why are there galaxies around supermassive black holes? Also why aren’t there galaxies anywhere else other than around supermassive black holes?

I’ve bookmarked this because I found it interesting. I would be very interested to hear more news on this. Thanks!

ive thought for awhile now that black holes form galaxies but since im not a scientist nobody cares about my theories. i dont believe that a big bang formed our universe. i believeall these gals will turned their matter back into the atomic form through the jets of black holes till all the gals are turned back into dust which then forms one massive star that goes super super nova and makes a huge black hole that forms more smaller but massive stars that aGAIN blow up to form quasars which make their own stars LIKE OUR SUN. sounds confusing but i believe it. the universe never just started. its always bn here and we'll be recycled back in dust and itll all start over again.

im totally with you nick, the universe has been present always, everlasting, and works like an endless recycling machine of matter, time is irrelevant to the universe, time only exists in our thoughts as a measurement stick for everything........the bang is lie created by church in alliance with the cartels of world domination, because they were losing ground with the advancement of cosmological discoveries, that were showing to the people that after all there was no god......so they invented the bang theory showing that what got an start must have an end(not totally true), making the argument of outside creation and its creator(the kalam argument).........every week arrives news and clues showing even more as time goes on the bang is totally inconsistent (star aging, g clusters, galaxy formation, flawless inflation, etc......)......unfortunately, exists a campaign against all scientists that dare to bring logical theories for the universe and life evolution, i call it the cosmological inquisition, and church and his allied cartels use money, power, and media as modern weapons for career disruption and public humiliation of the people who dare to speak against their will.....

And I´m totally with both of you, Nick and Pedro, and I can´t understand that DailyGalaxy keep these kind of articles coming without also bringing some articles about for instants the Electric Universe and Plasma Cosmology to balance these.

"Black holes" are nothing else but a dynamic funnel in a spherical electro-hydro-magnetic circuit, almost like the eye in a hurricane. Both phenomena’s are governed by electric ionization of gas and particles, creating different weather- or cosmic pressures, which again creates perpendicular swirling magnetic fields and spherical circuits with suction/”infolding” of gas and particles on one side of the funnel and outfolding on the opposite side.

So “black holes” “do not create the galactic host”, or vice versa, because it is all about a circuit of electric and magnetic formation in connection with even larger electric fields in cosmos.

It looks like HE0450-2958 builds his own galaxy. This is contrary to our common cosmological observation of the galaxy’s & black hole’s growth. What is the explanation of that? It is due to belated light effect phenomenon. The object we seeing is the reverse & delaying look of that object’s action at far earlier time. Its coordinate on Caelum constellation (south area of Galactic map) confirms the Universe nucleus post is at around Ursa Major & Leo constellation.

In my opinion, black holes definitely create galaxies. The question is were black holes created at the instant of the big bang. I say yes.
