EU-funded scientists have found that the gravitational well residing at the heart of a nearby galaxy radiates sufficient energy into local space to change the star formation rate.
The jets produced by supermassive black holes are known to heat up surrounding gas, making it impossible for birth clouds to condense and collapse into stars. In the EU-funded project BHS SHAPING GALAXIES (Black holes altering galaxy evolution: how to find them?), this effect has been witnessed in detail.
