NGC 4753 is a lenticular galaxy located about 60 million light-years away [2] in the constellation of Virgo. [3] NGC 4753 was discovered by astronomer William Herschel on February 22, 1784. [4] It is notable for having distinct dust lanes that surround its nucleus. [5] It is a member of the NGC 4753 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. [6]
The distribution of dust in NGC 4753 lies in an inclined disk wrapped several times around the nucleus. The material in the disk may have been accreted from the merger of a gas rich dwarf galaxy. Over several orbital periods, the accreted material eventually smeared out into a disk. Differential precession that occurred after the accretion event caused the disk to twist. Eventually, the disk settled into a fixed orientation with respect to the galaxy. The age of the disk is estimated to be around half a billion to a billion years. [7]
Another explanation suggests that the dust in NGC 4753 originated from red giant stars in the galaxy. [8]
Analysis of the twisted disk in NGC 4753 by Steiman-Cameron et al. revealed that most of the mass in the galaxy lies in a slightly flattened spherical halo of dark matter. [7] [9]
NGC 4753 has an estimated population of 1070 ± 120 globular clusters. [10]
NGC 4753 has been the host of two supernovae, SN 1965I and SN 1983G. [11] [12]
On June 18, 1965 a type Ia supernova was discovered in NGC 4753. [12] [13]
On April 4, 1983, Astronomer Robert Evan discovered a type Ia supernova known as SN 1983g in NGC 4753. [14]
NGC 4753 is a member of its own galaxy group, known as the NGC 4753 Group. [15] [6] [5] The NGC 4753 Group is located near the southern edge of the Virgo Cluster. [6] The group, along with other groups of galaxies form part of a filament that extends off from the southern border of the Virgo Cluster that is called the Virgo II Groups. [15] [6]
Messier 84 or M84, also known as NGC 4374, is a giant elliptical or lenticular galaxy in the constellation Virgo. Charles Messier discovered the object in 1781 in a systematic search for "nebulous objects" in the night sky. It is the 84th object in the Messier Catalogue and in the heavily populated core of the Virgo Cluster of galaxies, part of the local supercluster.
Messier 108 is a barred spiral galaxy about 28 million light-years away from Earth in the northern constellation Ursa Major. It was discovered by Pierre Méchain in 1781 or 1782. From the Earth, this galaxy is seen almost edge-on.
NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs, similar to the distance of M101 in the constellation Ursa Major. Both were once considered to be part of the Local Group, but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.
NGC 4526 is a lenticular galaxy with an embedded dusty disc, located approximately 55 million light-years from the Solar System in the Virgo constellation and discovered on 13 April 1784 by William Herschel.
NGC 4639 is a barred spiral galaxy located in the equatorial constellation of Virgo. It was discovered by German-born astronomer William Herschel on April 12, 1784. John L. E. Dreyer described it as "pretty bright, small, extended, mottled but not resolved, 12th magnitude star 1 arcmin to southeast". This is a relatively nearby galaxy, lying approximately 72 million light-years away from the Milky Way. It is a companion to NGC 4654, and the two appear to have interacted roughly 500 million years ago. NGC 4639 is a member of the Virgo Cluster.
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.
NGC 4424 is a spiral galaxy located in the equatorial constellation of Virgo. It was discovered February 27, 1865 by German astronomer Heinrich Louis d'Arrest. This galaxy is located at a distance of 13.5 million light years and is receding with a heliocentric radial velocity of 442 km/s. It has a morphological class of SB(s)a, which normally indicates a spiral galaxy with a barred structure (SB), no inner ring feature (s), and tightly-wound spiral arms (a). The galactic plane is inclined at an angle of 62° to the line of sight from the Earth. It is a likely member of the Virgo Cluster of galaxies.
NGC 4699 is an intermediate spiral galaxy located in the constellation Virgo. It is located at a distance of circa 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.
NGC 4457 is an intermediate spiral galaxy located about 55 million light-years away in the constellation of Virgo. It is also classified as a LINER galaxy, a class of active galaxy defined by their spectral line emissions. NGC 4457 Is inclined by about 33°. It was discovered by astronomer William Herschel on February 23, 1784. Despite being listed in the Virgo Cluster Catalog as VCC 1145, NGC 4457 is a member of the Virgo II Groups which form an extension of the Virgo cluster.
NGC 4523 is a Magellanic spiral galaxy located about 35 to 50 million light-years away in the constellation Coma Berenices. It was discovered by astronomer Heinrich d'Arrest on April 19, 1865. NGC 4523 is a member of the Virgo Cluster. A distance of for NGC 4523 was derived from using yellow supergiants in the galaxy as standard candles.
