Characteristics

Arp 107 is made of two separate galaxies. The larger galaxy to the left is PGC 32620, and the smaller galaxy to the right is PGC 32628, (as depicted in the Hubble image). These galaxies are different in which one is a spiral galaxy while the other one is an elliptical galaxy being connected by a bridge and tidal tail made of dust and gas. [4] [5]

The nucleus of PGC 32620 is active and it is classified as a type 2 Seyfert galaxy. [6] [7] Additionally, the galaxy is depicted having a ring-like appearance. The most likely scenario for this appearance in PGC 32620, is that the elliptical galaxy penetrated through its disk, causing it to become semi-annular with a large single spiral arm protruding out. [4] [7] This spiral arm in turn, then branches out in a form of a tidal arm, where star-forming regions of both old and young star populations are present. [8]

NGC 514 is a low-luminosity, intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83 million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel. The general form of the galaxy is specified by its morphological classification of SAB(rs)c, which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus with an extended region that displays weak emission lines in the optical range, but not in the near infrared. The suspected supermassive black hole at the core has an estimated mass of 3.2×106 M☉.

NGC 1433 is a barred spiral galaxy with a double ring structure located in the constellation of Horologium. It is at a distance of 46 million light-years from Earth. It is a Seyfert galaxy with an active galactic nucleus. The central region of the galaxy displays intense star formation activity, with an irregular star-forming ring of 5″ radius and weak radio wave emission. Star formation is also noticeable in the spiral arms but not the bar of the galaxy. NGC 1433 is being studied as part of a survey of 50 nearby galaxies known as the Legacy ExtraGalactic UV Survey (LEGUS). A jet of material flowing away from the central black hole of the galaxy extending for only 150 light-years has been found. It is the smallest molecular outflow ever observed in a galaxy beyond our own.
