LEDA 896325 also known as J1350-1634, is a spiral galaxy, class I seyfert galaxy, and a BL Lac object located in the constellation of Virgo. [1] The galaxy is approximately 1.42 billion light years (436 megaparsecs) away and has an apparent B magnitude of 17.13. [1] [2] It was discovered in 2003 by a HyperLEDA survey of 950,000 galaxies.

Physical Properties

LEDA 896325 is a very large spiral galaxy that is believed to be a field galaxy and is not associated with any known galaxy clusters. [1] [4] The galaxy is 309,000 light years (94,610 parsecs) across based on a distance of 1.42 billion light years away and an angular diameter of 44.3 arcsecs. [2]

In the galactic center of LEDA 896325 is a active galactic nucleus (AGN), and it is also a quasar. [1] In the active galactic nucleus it contains a central black hole with an estimated mass of 240 million M, which ejects large amounts of gas forming its large radio emissions. [4]

In 2025, it was discovered by RACS and GLEAM that LEDA 896325 was the host of ~2 megaparsec radio lobes. [4] The radio lobes are considered as Fanaroff-Riley class II, they are edge-brightened and are far more luminous than their counterpart, it is also classified as a spiral DRAGN. [4] It is also predicted to have episodic jet activity similar to J2345-0449. [4] The exact dimensions of the radio lobes are 2.24 megaparsecs or roughly 7,310,000 light years across based on an angular diameter of 22 arcmin, making it the second largest spiral-hosted radio galaxy discovered only behind NGC 6185.
