NGC 4809 is a Irregular Galaxy in the Virgo constellation. NGC 4809 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.2, NGC 4809 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

2024年1月29日 · In this paper, we present the clear evidence of metal enrichment by a type Ic SN 2011jm in the galaxy NGC 4809, utilizing high spatial resolution Integral Field Units (IFU) observations obtained from the Very Large Telescope …

2023年8月2日 · We find two different stellar mass surface density-stellar age relations in NGC 4809 and NGC 4810, and the stellar ages of NGC 4810 are systematically younger than in NGC 4809. Our study suggests that the merging stage of two dwarf galaxies can induce starburst activities at the interaction areas, despite the metal-deficient environment.

2024年3月2日 · 最近，天文学家们在研究银河系NGC 4809中的一颗超新星SN 2011jm时，发现了明显的金属污染。 尽管SN 2011jm周围的星际介质相对贫乏（约为太阳金属含量的0.25倍），但是研究人员们在这个区域内清晰地探测到了富含氧元素（约为太阳金属含量的0.35倍）以及一个显著 ...

NGC 4809 (također poznat kao Arp 277, IRAS 12523+0255, MCG 1-33-22, PGC 43969 i UGC 8034) je nepravilna galaksija koja je udaljena oko 42 miliona sg od Zemlje i nalazi se u sazviježđu Djevica. Najveći prečnik je 1,70 (21 hiljada sg) a najmanji 0,7 uglovnih minuta (8 hiljada sg).

NGC 4809 is the larger member of an interacting pair with NGC 4810 just 0.8' S. 18" (3/30/05): very faint, very small, slightly elongated. This galaxy is nearly attached to the north side of NGC 4810.
