Wandering Black Hole in a Dwarf Galaxy

In our traditional view, black holes are usually thought to “reside” at the centers of galaxies. However, a recent study has discovered a wondering black hole in a dwarf galaxy about 230 million light-years away (redshift z = 0.017). Unlike ​the norm, this black hole is not located at the galactic center but is offset by nearly ...
