Munich, December 1 (ANI): Recent observations by astronomers have indicated that black holes may be “building” their own host galaxies.

This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars.

“The ‘chicken and egg’ question of whether a galaxy or its black hole comes first is one of the most debated subjects in astrophysics today,” said lead author David Elbaz.

“Our study suggests that supermassive black holes can trigger the formation of stars, thus ‘building’ their own host galaxies. This link could also explain why galaxies hosting larger black holes have more stars,” he added.

To reach such an extraordinary conclusion, the team of astronomers conducted extensive observations of a peculiar object, the nearby quasar HE0450-2958, which is the only one for which a host galaxy has not yet been detected.

HE0450-2958 is located some 5 billion light-years away.

Until now, 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,” said 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,” he added.

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. (ANI)
