[1] [2] [3] Discovered on March 30, 1887, by American astronomer Lewis Swift, [4] NGC 5920 is 711 million light-years distant from planet Earth. [5] It is a narrow-line radio galaxy [6] and about 300,000 light-years in diameter.

Characteristics

NGC 5920 has an active galactic nucleus. It presents a radio jet. In addition, it hosts a radio source in its core called 3C 318.1, indicating emissions of strong radio waves. [7] NGC 5920 was studied by Chandra-MUSE, in which X-ray and optical filament analysis in clusters were carried out. [8] The main purpose for this was to find the excitation process responsible for increased filament emission. The research was further improved by following the cold gas phase and through study of intensive ratios in emission lines that caused the excitation. Researchers found that, there was a spatial connection between the filaments that are cold and having lower metal abundance levels. [8]

Group Membership

NGC 5920 is the brightest cluster galaxy of a small galaxy cluster which is known as MKW 3. [9] [10] Apart from it, another radio galaxy NGC 5919, is also located there. [4]

<span class="mw-page-title-main">Serpens</span> Constellation split into two non-contiguous parts

Serpens is a constellation in the northern celestial hemisphere. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations designated by the International Astronomical Union. It is unique among the modern constellations in being split into two non-contiguous parts, Serpens Caput to the west and Serpens Cauda to the east. Between these two halves lies the constellation of Ophiuchus, the "Serpent-Bearer". In figurative representations, the body of the serpent is represented as passing behind Ophiuchus between Mu Serpentis in Serpens Caput and Nu Serpentis in Serpens Cauda.

Centaurus A is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, in New South Wales, Australia. There is considerable debate in the literature regarding the galaxy's fundamental properties such as its Hubble type and distance. NGC 5128 is one of the closest radio galaxies to Earth, so its active galactic nucleus has been extensively studied by professional astronomers. The galaxy is also the fifth-brightest in the sky, making it an ideal amateur astronomy target. It is only visible from the southern hemisphere and low northern latitudes.

Messier 86 is an elliptical or lenticular galaxy in the constellation Virgo. It was discovered by Charles Messier in 1781. M86 lies in the heart of the Virgo Cluster of galaxies and forms a most conspicuous group with another large galaxy known as Messier 84. It displays the highest blue shift of all Messier objects, as it is, net of its other vectors of travel, approaching the Milky Way at 244 km/s. This is due to both galaxies falling roughly towards the center of the Virgo cluster from opposing ends.
