VLA makes first direct image of key feature of powerful radio galaxies
Astronomers used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to make the first direct image of a dusty, doughnut-shaped feature surrounding the supermassive black hole at the core of one of the most powerful radio galaxies in the Universe—a feature first postulated by theorists nearly four decades ago as an essential part of such objects.
