black hole could be many times more massive than its largest known compete tor, which is estimated but not confirmed to be between 6 billion and 37 billion solar masses in size.It

central mass — the bulge of stars at the core.
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.
A leading theory is that star -
making materials are scattered by torrents of energy released by a galaxy's
central supermassive
black hole as it sloppily devours matter.
«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.»
With these ultrasharp glasses, Ghez and Genzel have tracked the motion of individual stars around the
central black hole, called Sagittarius A *,

make 3 billion Suns — ends up in the
central region of the merged galaxy along with the two
black holes.
«The
black hole's inactivity [today] suggests that the
central few light years doesn't contain enough raw material to
make stars.
These «raindrops» eventually cool down enough to transform into star - forming clouds of cold molecular gas that end up
making «a swirling «puddle» of star - forming gas around the
central black hole.»
