Like every major galaxy, it has a supermassive black hole in its core — specifically, Andromeda's has a hefty 100 million times the mass of the Sun, making it far larger than our own Milky Way's 4 million mass central black hole.

Other evidence comes from the analysis of modern galaxies, most of which have central black holes whose masses seem to correlate closely with the properties of their host galaxies.

Many distant quasars — luminous galaxies, thought to be powered by large central black holes — are known to contain warm dust, which glows at infrared wavelengths.

«We know that these showers are linked to the jets because they're found in filaments and tendrils that wrap around the jets or hug the edges of giant bubbles that the jets have inflated,» said Tremblay, «And they end up making a swirling «puddle» of star - forming gas around the central black hole.»

A light drizzle of cooling gas provides enough fuel for the central black hole's jets to keep the rest of the galaxy's gas hot.

Using a few assumptions about the lensing galaxy, Carilli and his colleagues calculate that the CO gas is actually in a relatively small 13,000 light - year — wide disk surrounding the central black hole of the quasar.

That's because a compact source may be compact, not because it's young, but because gas within the galaxy is dense enough to prevent the jets from extending far from the central black hole; i.e. it remains compact despite it's age.

The star got too close to its galaxy's central black hole about 290 million years ago, and collisions among its torn - apart pieces caused an eruption of optical, ultraviolet and X-ray light that was first spotted by scientists in 2014.

Most major galaxies harbor supermassive central black holes.

According to one model, compact radio sources are young because the jets have not had time to reach far beyond the central black hole.

But recently it was observed that the mass of a central black hole correlates with the mass of the galaxy around it!

Such an «active galactic nucleus» (AGN) presumably arises when ultrahot gas falls into a galaxy's central black hole, and common wisdom held that the matter is tipped into the black hole when galaxies collide.

The culprit was most likely a star falling into a galaxy's central black hole.

Most galaxies in the universe revolve around central black holes, which feed voraciously on galactic gas and dust and spew out radiation.
