So which comes first, the black hole or the galaxy? The questions has vexed astrophysicists for ages, but European researchers think they may have figured out the answer. A recent study suggests supermassive black holes can spawn star formation, in essence creating their own host galaxies around them.
The team of astronomers observed a specific quasar (HE0450-2958 for all you space wonks) that, by all appearances, has no host galaxy. Researchers thought that perhaps the quasar's host galaxy was hidden behind a large mass of space dust, but using ESO's Very Large Telescope, they determined that this is not the case. What they did find is that an unrelated galaxy nearby is producing stars like it's going out of style -- something like 350 suns per year, 100 times more quickly than other galaxies in the universal neighborhood.
So what's the rush? It turns out that the frantic rate of star formation isn't a result of anything in the companion galaxy's construction, but of the one quasar itself. The quasar is bombarding the companion galaxy with highly energetic particles and fast moving gas streams, pumping it full of matter and energy. It is also inching toward the companion galaxy, where it will eventually merge and take up residency. At that point, all the matter and energy the quasar spewed into the companion galaxy will become its own galaxy.
As such, researchers think black hole jets could catalyze galaxy formation by providing the energy and matter necessary to create stars. The theory also provides an explanation as to why galaxies with more massive black holes contain more stars.
Neat, so if the black hole creates the galaxy, what creates the black hole? Perhaps it's an eternal yin and yang of cosmic proportions.
Anyway, will PopSci have anything on Climategate for its readers?
umm god, duhh
you peeps know I kid
god's mom, duhh
of course, the egg is the answer, anyone who believes otherwise also believes dark magic is responsible for satellite television, Elvis, and human existence
Well the Big Bang is the leading theory. The matter now is going from black holes to galaxies to black holes etc. They are like ripples after a splash.
yeah... but what caused the big bang? that's the real question. however, finding the answer to that will only change the real question to "what caused that". 'tis a conundrum(sp?)
