NGC 4051 is a spiral galaxy. It contains a supermassive black hole inside the center.
This galaxy was studied by the Multicolor Active Galactic Nuclei Monitoring 2m telescope.[1]
The galaxy is a Seyfert galaxy that emits bright X-rays. However, in early 1998 the X-ray emission ceased as observed in by the Beppo-SAX satellite.[2]
