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

Three supernovae have been observed in NGC 4699: SN 1948A (type unknown, mag. 17), [8] SN 1983K (type II-P, mag. 17), [9] and SN 2024muv (type Ia, mag. 14.5). [10] SN 1983K had a plateau-shaped light curve, and its spectra featured a progressive violet shift, which was explained by the presence of a preexisting outer shell of materials around the progenitor of the supernova. [11]

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. [12] It belongs to the Virgo II groups, an extension of the Virgo Cluster. [13]

Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope. Charles Messier added it to his catalogue of nebulous objects in March 1781.

Messier 61 is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779, six days before Charles Messier discovered the same galaxy. Messier had observed it on the same night as Oriani but had mistaken it for a comet. Its distance has been estimated to be 45.61 million light years from the Milky Way Galaxy. 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.

Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole. NGC 4217 is a possible companion galaxy of Messier 106.

NGC 4414, also known as the Dusty Spiral Galaxy, is an unbarred spiral galaxy about 62 million light-years away in the constellation Coma Berenices. It is a flocculent spiral galaxy, with short segments of spiral structure but without the dramatic well-defined spiral arms of a grand design spiral. Four supernovae have been observed in this galaxy: SN 1974G, SN 2013df, SN 2021J, and SN 2023hlf.

NGC 4945 (also known as Caldwell 83) is a barred spiral galaxy in the constellation Centaurus, visible near the star Xi Centauri. The galaxy was discovered by James Dunlop in 1826 and is thought to be similar to the Milky Way Galaxy, although X-ray observations show that NGC 4945 has an unusual energetic Seyfert 2 nucleus that might house a supermassive black hole. Around the nucleus of the galaxy, there is a dense disk of dust and gas, along with many dense star clusters. This object has an estimated mass of 1.4+1.4

NGC 3621 is a field spiral galaxy about 22 Mly (6.7 Mpc) away in the equatorial constellation of Hydra. It is comparatively bright and can be well seen in moderate-sized telescopes. The galaxy is around 93,000 ly (29,000 pc) across and is inclined at an angle of 66° from being viewed face on. It shines with a luminosity equal to 13 billion times that of the Sun.
