# astro: you might find erratic massive black holes in dwarf galaxies ...

<< The new VLA (Very Large Array) observations revealed that 13 of these galaxies have strong evidence for a massive black hole that is actively consuming surrounding material. (AA) were very surprised to find that, in roughly half of those 13 galaxies, the black hole is not at the center of the galaxy, unlike the case in larger galaxies, >>  Amy Reines.

<< The scientists said this indicates that the galaxies likely have merged with others earlier in their history. This is consistent with computer simulations predicting that roughly half of the massive black holes in dwarf galaxies will be found wandering in the outskirts of their galaxies. >>

<< This work has taught us that we must broaden our searches for massive black holes in dwarf galaxies beyond their centers to get a more complete understanding of the population and learn what mechanisms helped form the first massive black holes in the early Universe, >> Amy Reines.
