High-speed jets from a possible new class of galaxy. Seyfert galaxies are similar to spiral galaxies except that they have extraordinarily prominent, bright nuclei, sometimes as luminous as 100 billion Suns. Their huge energies are thought to be generated as matter falls towards a central supermassive black hole and accretes onto a circumnuclear disk around it. Observations distinguish between two types of Seyferts: those whose nuclear emission appears to be slightly obscured, thought to be the result of viewing the galaxy edge-on through an obscuring disk, and those seen face-on.
