NGC 4699 is an intermediate spiral galaxy located in the constellation Virgo. It is located at a distance of about 65 million light years from Earth, which, given its apparent dimensions, means that NGC 4699 is about 85,000 light years across. It was discovered by William Herschel in 1786. It is a member of the NGC 4699 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. [2]

Characteristics

NGC 4699 is a Seyfert like galaxy with very weak nuclear emission. [3] The galaxy features a bar that is 0.41 arcminutes long and a ring with diameter 1.95 arcminutes. [4] The galaxy features a large bulge which accounts for the 11.3% of the stellar mass of the galaxy and a large disky pseudobulge, which is larger than the strong bar. The disk within the bulge features tightly wrapped spiral arms. [5] There are a lot of HII regions in the disk. [3] The galaxy has an extended type-III outer disk, [6] with low central surface magnitude and which is thicker than the inner disk. [7]

Supernovae

Two supernovae have been observed in NGC 4699, SN 1948A and SN 1983K. SN 1983K was a type II supernova with plateau-shaped light curve. The spectra of the supernova featured a progressive violet swift, which was explained by the presence of a proexisting outer shell of materials around the progenitor of the supernova. [8]

Nearby galaxies

NGC 4699 belongs in the NGC 4697 group according to Makarov and Karachentsev. Other members of the group include NGC 4697, NGC 4674, NGC 4700, NGC 4731, NGC 4742, NGC 4775, NGC 4781, NGC 4784, NGC 4790, NGC 4813, NGC 4948 and NGC 4958. [9] It belongs to the Virgo II groups, an extension of the Virgo Cluster. [10]

NGC 4536 is an intermediate spiral galaxy in the constellation Virgo located about 10° south of the midpoint of the Virgo cluster. However, it is not considered a member of the cluster. Rather, it is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. The morphological classification in the De Vaucouleurs system is SAB(rs)bc, which indicates it is a weakly barred spiral galaxy with a hint of an inner ring structure plus moderate to loosely wound arms. It does not have a classical bulge around the nucleus.

NGC 4666 is a spiral galaxy in the equatorial constellation of Virgo, located at a distance of approximately 55 megalight-years from the Milky Way. It was discovered by the German-born astronomer William Herschel on February 22, 1784. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. John L. E. Dreyer described it as "bright, very large, much extended 45°±, pretty suddenly brighter middle". It is a member of an interacting system with NGC 4668 and a dwarf galaxy, and belongs to a small group that also includes NGC 4632.
