NGC 3432 is an edge-on spiral galaxy that can be found in the northern constellation of Leo Minor. It was discovered by German-British astronomer William Herschel on March 19, 1787. This galaxy is located at a distance of 40 million light-years (12.3 Mpc) from the Milky Way. It is interacting with UGC 5983, a nearby dwarf galaxy, and features tidal filaments and intense star formation. Because of these features, it was listed in Halton Arp's Atlas of Peculiar Galaxies.
Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus, and "it is thought that the smaller galaxy has actually passed through the larger one."
UGC 8335 is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies.
NGC 521, also occasionally referred to as PGC 5190 or UGC 962, is a barred spiral galaxy located approximately 224 million light-years from the Solar System in the constellation Cetus. It was discovered on 8 October 1785 by astronomer William Herschel.
NGC 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. NGC 5395 and NGC 5394 are included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
NGC 3294 is a spiral galaxy in the constellation Leo Minor. It was discovered by William Herschel on Mar 17, 1787. It is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. The galaxy is located at a distance of 98 million light years and is receding with a heliocentric radial velocity of 1,586 km/s. The morphological class of NGC 3294 is SA(rs)bc, which means this is a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderately wound spiral arms (bc).
IC 3971 is a spiral galaxy located approximately 1 billion light-years away from the Solar System, in the constellation of Coma Berenices. It was first discovered in January 1904 by German astronomer Max Wolf. According to SIMBAD database, it is a LINER type galaxy with an active nucleus.
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 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation. It is located 500 million light-years away from the Solar System and has a diameter of 290,000 light-years, making it slightly more massive compared to the Milky Way. The galaxy is moving away at a speed of 11,162 kilometers per second.
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.
NGC 6261 is a lenticular galaxy in the constellation of Hercules. It is located 470 million light-years away from the Solar System and has an approximate diameter of 200,000 light-years.
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.
NGC 3746 is a large barred spiral galaxy with a ring structure located in the Leo constellation. It is located 449 million light-years from the Solar System and has an approximate diameter of 165,000 light-years. NGC 3746 was discovered by Ralph Copeland on 9 February 1874 with subsequent observations made by Hermann Kobold, Lawrence Parsons and John Louis Emil Dreyer.
NGC 3750 is a lenticular galaxy with a bar located in the constellation of Leo. It is located 450 million light-years from the Solar System and was discovered by Ralph Copeland on February 9, 1874.
NGC 3754 is a small barred spiral galaxy located in Leo. It is located 447 million light-years away from the Solar System and was discovered on April 5, 1874, by Ralph Copeland.
NGC 3509 known as Arp 335, is a barred spiral galaxy located in the constellation Leo. It is located 340 million light-years from the Solar System. NGC 3509 was discovered by astronomer William Herschel on December 30, 1786.
NGC 3800 is an intermediate spiral galaxy located in the constellation Leo. Its speed relative to the cosmic microwave background is 3,653 ± 24 km/s, which corresponds to a Hubble distance of 53.9 ± 3.8 Mpc. NGC 3800 was discovered by German-British astronomer William Herschel in 1784.
NGC 3799 is a barred spiral galaxy located in the constellation Leo. Its speed relative to the cosmic microwave background is 3,659 ± 24 km/s, which corresponds to a Hubble distance of 54.0 ± 3.8 Mpc. NGC 3799 was discovered by British astronomer John Herschel in 1832.
