NGC 4395

NGC 4395 is a barred spiral galaxy in the constellation Canes Venatici, which is 14 million light-years away and a member of the Canes Venatici I - group. She is an active galaxy with a very bright center, ie with an active galactic nucleus (AGN ), it is a Seyfert 1 galaxy.

Special

In NGC 4395 the then smallest supermassive black hole with a mass of 10,000 to 100,000 solar masses was of British and Japanese scientists, led by Kazushi Iwasawa and Andrew Fabian of Cambridge University with the help of the Japanese X-ray satellite "Advanced Satellite for Cosmology and Astrophysics" ( ASCA ) found. Thus, it was 100 times smaller than any previously known black holes of this type. A short time later, an even smaller hole was discovered in the galaxy M82.

In addition, there are in the galaxy more H II regions, three of which have been found as separate objects the way to the New General Catalogue: NGC 4399, NGC 4400 and NGC 4,401th

Discovery

NGC 4395 was discovered on January 2, 1786 by the German - British astronomer William Herschel.
