SDSS J102709.94+390805.1 known as [BOG2010] 1075981, is a radio galaxy located in the constellation of Leo Minor. The redshift of the galaxy is (z) 0.337[1] and it was first discovered as an astronomical radio source by astronomers from the Bologna Sky Survey in February 1985.[2]
Description
[edit]SDSS J102709.94+390805.1 is an elliptical galaxy with an morphological classification of Type E.[3] It is a red luminous galaxy[4] residing as the brightest cluster galaxy (BCG) of the galaxy cluster, WHL J102709.9+390805, with 23 confirmed galaxy member candidates. The r-band magnitude of the galaxy is found to be 17.47 magnitude.[5][6] Its absolute magnitude is -23.76.[7]
The galaxy hosts an active galactic nucleus. It is classified as a Fanaroff-Riley Class Type I radio galaxy of non bent-tail subtype with its total flux density measured to be 43.60 mJy obtained by NRAO VLA Sky Survey (NVSS) at 1.4 GHz frequencies.[7] It also contains an ultra steep spectrum source with the spectral index of -1.02α between 352 MHz and 1.4 GHz. The total radio luminosity is found to be 24.93 W Hz−1 at 1.4 GHz.[8]
The radio morphology is mainly elongated, described by a single elliptical profile component or as a compact point-like component according to NVSS contour imaging. There is a presence of a radio core with its total core flux density estimated as 40.09 mJy. The total radio flux density is 43.40 mJy. The luminosity distance of the source is 1799.3 megaparsecs.[3] The radio power has been calculated as 16.84 × 1024 WHz−1.[9]
