Supermassive Black Hole Triggered Star Formation in Dwarf Galaxy astronomy space science
A pullout of the central region of the dwarf starburst galaxy Henize 2-10 traces an outflow, or bridge of hot gas 230 light-years long, connecting the galaxy’s massive black hole and a star-forming region. Hubble data on the velocity of the outflow from the black hole, as well as the age of the young stars, indicates a causal relationship between the two.
That connection is an outflow of gas stretching across space like an umbilical cord to a bright stellar nursery.Hubble spectroscopy shows the outflow was moving about 1.6 million kmh , slamming into the dense gas like a garden hose hitting a pile of dirt and spreading out.This is the opposite effect of what’s seen in larger galaxies, where material falling toward the black hole is whisked away by surrounding magnetic fields, forming blazing jets of plasma moving at close to the speed of light.
But with the less-massive black hole in Henize 2-10, and its gentler outflow, gas was compressed just enough to precipitate new star formation
