Black holes can not only rip stars apart, but they can also trigger star formation, as scientists have now seen in a nearby dwarf galaxy.
In the new study, the researchers focused on a tendril of gas from the heart of Henize 2-10 about 490 light-years long, in which electrically charged ionized gas is flowing as fast as 1.1 million mph . This outflow was connected like an umbilical cord to a bright stellar nursery about 230 light-years from Henize 2-10's core.
This outflow slammed into the dense gas of the stellar nursery like a garden hose spewing onto a pile of dirt, leading water to spread outward. The researchers found newborn star clusters about 4 million years old and upwards of 100,000 times the mass of the sun dotted the path of the outflow's spread, Schutte said.
A closer view of the central region of the dwarf galaxy Henize 2-10 shows the supermassive black hole and the outflow of hot gas.Hubble Space Telescope , the scientists detected a corkscrew-like pattern in the speed of the gas in the outflow. Their computer models suggested this was likely due to the precessing, or wobbling, of a black hole. Since a supernova remnant would not cause such a pattern, this suggests that Henize 2-10's core does indeed host a black hole.
