UGC 4457 PGC 23935, Arp 58, IRAS 08290+1922, MCG +03-22-017, VV 413, LEDA 23935, Z 89-40 |
UGC 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation. [1] [2] [3] It is located 500 million light-years away from the Solar System [3] and has a diameter of 290,000 light-years, [1] making it slightly more massive compared to the Milky Way. [4] The galaxy is moving away at a speed of 11,162 kilometers per second. [1]
UGC 4457 is interacting with the compact galaxy, PGC 23937. Together, they form Arp 58 and are classified under spiral galaxies that have small companions with high surface brightness. [5] UGC 4457 shows disturbed spiral arms, indicating signs of velocity disturbance levels and regions of scattered ionized gas, typically normal for interacting galaxies. A faint spiral bridge can be seen thus representing the remains of an older mode of spiral waves. [6]
NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo (Peacock). It is considered as a Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core. It also has at least one distorted companion galaxy superficially similar to one of the Magellanic Clouds. It was discovered from Parramatta in Australia by Scottish astronomer James Dunlop on 30 June 1826.
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 6040 is a spiral galaxy located about 550 million light-years away in the constellation Hercules. NGC 6040 was discovered by astronomer Édouard Stephan on June 27, 1870. NGC 6040 is interacting with the lenticular galaxy PGC 56942. As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942. NGC 6040 and PGC 56942 are both members of the Hercules Cluster.
NGC 5953 is a peculiar spiral galaxy in the constellation Serpens. The galaxy lies about 80 million light years away from Earth, which means, given its apparent dimensions, that NGC 5953 is approximately 35,000 light years across. It was discovered by William Herschel on April 17, 1784. NGC 5953 interacts with NGC 5954 forming a pair known as Arp 91.
UGC 717 is a barred spiral galaxy located in Pisces. The galaxy is located 520 million light-years away from the Solar System. It is designated as Arp 11 in the Atlas of Peculiar Galaxies which was produced by Halton Arp. UGC 717 falls under the category of spirals that have split-arms. It is known to have a LINER active galactic nucleus according to SIMBAD.
Arp 146 are a pair of interacting galaxies located 1.05 billion light-years away from Earth in the Cetus constellation. According to a study, one galaxy appears to have passed through another, leaving behind a ring formed from the bridge material and remnants of the nucleus. Under the Atlas of Peculiar Galaxies created by Halton Arp, they are categorized under galaxies that have associated rings.
PGC 4789 is a distant barred spiral galaxy in the Pisces constellation. It is located 675 million light-years from the Milky Way and seems to be interacting with its neighboring galaxies. it is known as Arp 48 in the Atlas of Peculiar Galaxies catalogue. In this class, PGC 4789 falls into galaxies that have at least one low surface brightness companion.
UGC 934, known as PGC 5085, is a large spiral galaxy about 470 million light-years away from the solar system. It is located in the constellation of Pisces and about 285,000 thousand light-years in diameter. With its neighboring galaxy PGC 212740, they together form Arp 70, the 70th number in the Atlas of Peculiar Galaxies which was created by Halton Arp. In this class, they fall under spiral galaxies that have a small high-surface brightness companions.
UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the solar system in the Lynx constellation. The galaxies are being distorted through gravitational interactions with each other.
UGC 1840 known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the Solar System in the Andromeda constellation. Made up of two galaxies, UGC 1840 NED01 and UGC 1840 NED02, the two galaxies had recently collided with each other in which the elliptical galaxy has penetrated through the spiral galaxy's nucleus leaving a hole in its middle, thus forming a ring galaxy. With a diameter of 1.3 arc minutes, close to 100,000 thousand light-years, they are roughly the same size as the Milky Way.
UGC 224 known as Arp 201, are pair of interacting galaxies located 860 million light-years in the constellation of Pisces.
UGC 2812 known as Arp 219, are a pair of interacting galaxies located 470 million light-years away in the Eridanus constellation. Both galaxies appeared to be distorted and tangled with each other which suggests their inevitable merging to form an elliptical galaxy. Moreover, they present a near-infrared spectra which could result from starbursts. Both objects are part of Atlas of Peculiar galaxies, where they are categorized under galaxies that have adjacent loops which are a manifestation of structures that were formed by gravitational interactions.
UGC 6697 is a large irregular spiral galaxy with a bar located in the Leo constellation. It is located 378 million light-years from the Solar System and has an estimated diameter of 205,000 light-years. UGC 6697 is considered a starburst galaxy which produces high rates of star formation.
SDSSCGB 10189 is a trio of interacting galaxies that is located in the constellation of Boötes. They are located 1.04 billion light-years away from the Solar System and are gravitationally interacting.
NGC 3753 is a large spiral galaxy with a bar located in the Leo constellation. It is located 435 million light-years away from the Solar System and was discovered on February 9, 1874, by Ralph Copeland.
NGC 3748 is a lenticular galaxy with a bar located in the Leo constellation. It is located 440 million light-years away from the Solar System and was discovered by Ralph Copeland on April 5, 1874, but also observed by Hermann Kobold, Lawrence Parsons and John Louis Emil Dreyer.
