PGC 1228197 known as WINGS J211347.41+022834.9 and JO206, is a large spiral galaxy located 700 million light-years away towards the constellation of Aquarius. [1] [2] The galaxy is estimated to be at least 160,000 light-years in diameter, making it somehow bigger than the Milky Way. With a radial velocity of 15,226 kilometers per second, it is slowly drifting away. [3]

PGC 1228197 is a member of a poor galaxy cluster called II ZW 108. It has a stellar mass of 8.5 × 1010 M○. [4]

PGC 1228197 is classified as a jellyfish galaxy. [5] [6] It has a lengthy tail that is ≥90 kpc wide, with ionized gas stripped from the galaxy. [7] The galaxy is surrounded by its own magnetized intracluster medium drape. [8]

Such process is caused when it interacts with other galaxies causing it to run into intracluster medium. The galaxy then undergoes a process of ram-pressure where its gas is stripped, forming long galactic tendrils of stars. [5] [9] [10] Because matter is accreted into its supermassive black hole, its active galactic nucleus is trigged. [11]

Marc Postman is an American astronomer at the Space Telescope Science Institute in Baltimore, Maryland, United States. His research interests include observational studies of the formation and evolution of galaxies and large scale structure in the universe. His work focuses on determining, observationally, the relationships between galaxy-scale phenomena and the surrounding large-scale environment and matter distribution. His recent research includes characterizing the properties of brightest cluster galaxies and placing new constraints on the cosmic optical background.

<span class="mw-page-title-main">Tidal disruption event</span> Pulling apart of a star by tidal forces when it gets too close to a supermassive black hole

A tidal disruption event (TDE) is a transient astronomical source produced when a star passes so close to a supermassive black hole (SMBH) that it is pulled apart by the black hole's tidal force. The star undergoes spaghettification, producing a tidal stream of material that loops around the black hole. Some portion of the stellar material is captured into orbit, forming an accretion disk around the black hole, which emits electromagnetic radiation. In a small fraction of TDEs, a relativistic jet is also produced. As the material in the disk is gradually consumed by the black hole, the TDE fades over several months or years.

Reticulum II is a dwarf galaxy in the Local Group. Reticulum II was discovered in 2015 by analysing images from the Dark Energy Survey. It is a satellite of the Magellanic Clouds and was probably captured relatively recently. Like other dwarf spheroidal galaxies, its stellar population is old: the galaxy was quenched before 11.5 billion years ago.

NGC 541 is a lenticular galaxy located in the constellation Cetus. It is located at a distance of about 230 million light years from Earth, which, given its apparent dimensions, means that NGC 541 is about 130,000 light years across. It was discovered by Heinrich d'Arrest on October 30, 1864. It is a member of the Abell 194 galaxy cluster and is included in the Atlas of Peculiar Galaxies in the category galaxies with nearby fragments.

PGC 65543, is a spiral galaxy, with extensive star forming regions, located in Indus. It is 650 million light-years away from the Solar System and approximately measuring 90,000 light-years in diameter. The tidal interactions from certain galaxies which PGC 65543 is moving towards to, have caused it to get distorted. Its star-forming gas and dust are dynamically stripped by ram-pressure and formed into tendrils that stretch outwards, thus gives an appearance of a jellyfish galaxy.
