NGC 4869 is an elliptical galaxy located in the constellation of Coma Berenices. It is located 343 million light years from Earth. [1] The galaxy was discovered by William Herschel in April 1785 but also observed by both John Herschel and Heinrich d'Arrest, in March 1827 and May 1863 respectively. [2] It is a member of the Coma Cluster [1] [3] with a small companion galaxy at a position angle of 325°. [4]

Characteristics

NGC 4869 is classified as a radio galaxy with a faint radio core with two oppositely directed radio jets and a lengthy low-surface brightness tail. [5] It has an estimated γ-ray luminosity of Lγ ≤ 4 x 1039 erg s-1 like NGC 4874. [6] There is also an elongated absorption feature in the galaxy, possibly representing an edge on disk. [3]

NGC 4869 contains a narrow angle tailed radio source. [7] [8] The source is found lying towards the central region of the Coma Cluster by 111 kpc. [5] It shows a mean fractional polarization of 18% at 4.535 GHz and 21% at 8.465 GHz [7] and a large-scale structure that is almost 200 kpc. [5] A characteristic feature of the source, is a sharp bend towards a north direction at 3’5 from the host galaxy's position. [5]

According to a Chandra X-ray image of NGC 4869, a straight collimated jet is seen flaring when traversing a surface brightness edge. [5]

Supermassive black hole

The supermassive black hole in NGC 4869 is estimated to be 1.32 x 108 Mʘ (108.12 Mʘ) based on a study made by Jong-Hak Woo and Urry in 2002. [9]

NGC 2865 is an isolated elliptical galaxy in the equatorial constellation of Hydra.
