RX J1750.2+3504 BCG (Short for RX J1750.2+3504 Brightest Cluster Galaxy) is a massive elliptical galaxy located in the constellation of Hercules. The redshift of the galaxy is (z) 0.170[1] and it is the brightest cluster galaxy of the X-ray galaxy cluster, RX J1750.2+3504.[2][3][4]
Description
RX J1750.2+3504 BCG is categorized as a central cluster galaxy of RX J1750.2+3504. The optical spectrum of the BCG displays emission lines including singly ionized nitrogen [N II] and singly ionized sulfur [S II] detected in red emission lines. The emission line fluxes for both of these elements are 2.9+0.1−0.1 and 0.7+0.2−0.1 × 1015 erg cm−2 s−1 respectively. The total hydrogen-alpha emission line luminosity is 41.23 erg s−1.[2]
The BCG hosts a strong radio source, classifying it as a radio galaxy. The source appears mainly core-dominated and it has a flat radio spectrum. The radio core is estimated to have a total flux density of 31.9 mJy. The flux contribution of the core at 10 GHz frequencies is 26.3 ± 4.1 mJy with a flat index at 0.47 ± 0.03. The non-core component at 1 GHz frequencies is less than 25.4 mJy.[3] The radio emission of the BCG is mainly core-dominated too, with a total radio flux of 69 mJy at 1.4 GHz.[5] The BCG is offset from the X-ray emission peak by 27.8 kiloparsecs.[6]
The supermassive black hole lying inside the center of the BCG has a mass of 9.91 ± 0.04 M☉ based on calculation of its K-band bulge luminosity. with another study estimating the black hole mass as 11.08 ± 0.15 M☉ according to a fundamental plane measurement.[7][8] The total absolute K-band magnitude of the bulge is estimated to be -27.3 ± 0.05, with the stellar bulge having a stellar mass of 12.17 ± 0.04 M☉.[7][8]
