Arp 25
One of the many starburst spiral arms contains an intermediate mass black hole with 50,000 times the mass of the Sun, named NGC 2276-3c. NGC 2276-3c has produced two jets: a large-scale radio jet, approximately 2,000 light years long, and an "inner jet" about 6 light years long. The galaxy shows an enhanced rate of star formation that may have been triggered by a collision with a dwarf galaxy, or by the gravitational interaction with its neighbor compressing gas and dust.
NGC 2276 was discovered by Friedrich August Theodor Winnecke on 26 June 1876. In the Atlas of Peculiar Galaxies, the galaxy is mentioned twice, once as Arp 25, in the category spiral galaxies with one heavy arm, and with NGC 2300 as Arp 114, in the category elliptical galaxies close to and perturbing spiral galaxies.
