Black holes help with star birth

A study shows the unexpected effect of black holes beyond their own galaxies

 E-Mail Credit: Gabriel Pérez Díaz, SMM (IAC) and Dylan Nelson (Illustris-TNG). At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region around the centre of the galaxy. Even though these objects are thousands of millions of times smaller than their host galaxies our current view is that the Universe can be understood only if the evolution of galaxies is regulated by the activity of these black holes, because without them the observed properties of the galaxies cannot be explained. Theoretical predictions suggest that as these black holes grow they generate sufficient energy to heat up and drive out the gas within galaxies to great distances. Observing and describing the mechanism by which this energy interacts with galaxies and modifies their evolution is therefore a basic question in present day Astrophysics.

Wind from supermassive black holes may help small galaxies thrive

Some supermassive black holes blast out powerful winds that astrophysicists suspected could kill small neighbouring galaxies – but it turns out they actually clear a spot for those small galaxies to settle into

Study Shows Unexpected Effect of Black Holes Beyond Their Own Galaxies

"Surprisingly we found that the satellite galaxies formed more or fewer stars depending on their orientation with respect to the central galaxy"
