Radio galaxy in the constellation Draco
3C 356 is a distant radio galaxy [ 1] [ 2] located in the constellation of Draco , hosted by a merging pair of elliptical galaxies located at redshift (z) 1.079[ 3] with two radio cores having a separation gap of 5 arcseconds .[ 4] [ 5] It was first discovered as an astronomical radio source by P. Veron from a 3C revised catalogue in 1966[ 6] and such, shows an alignment effect at both wavelengths .[ 7] The X-ray source luminosity for this galaxy is estimated to be 2.5 x 1044 erg s−1 .[ 2]
Description
3C 356 contains a double compact source with a 170° position angle . The source is found weakly depolarized in south-east direction closer to the central region. There is a presence of a northern object displaying a more ionized emission line spectrum likely the source's origin. In additional, the northern component is more compact but has an extension directly south by 3 arcseconds.[ 8] According to Hubble Space Telescope (HST) imaging of a northwest component, this shows a high surface brightness conelike structure with a much fainter extension.[ 9]
The radio structure of 3C 356 is complex. Its radio core position is unresolved with a diffused region peaking 5 arcseconds away at a position angle of 150° and a radio axis of 162°.[ 10] There are two radio lobes in 3C 356 are located 15 arcseconds and 30 arcseconds in both directions.[ 3] According to Very Large Array radio mapping, both northwestern and southeastern lobes are shown enlarged and overlaid polarized . In the southeastern lobe, there are three compact structures of equal brightness. The northwestern lobe on the other hand, contains a defined hot spot and more extended emission .[ 11]
According to deep near-infrared imaging taken via Subaru Telescope , 3C 356 is found connected with a poor cluster of galaxies .[ 12] A stellar mass of 4 x 1011 Mʘ has also been calculated for the spectral energy distribution of the galaxy as well, with the supermassive black hole mass being 8.74 ± 0.42 Mʘ .[ 13]
