WISEA J160318.98+031644.8

Description

This galaxy is a giant elliptical of type E morphology and a luminous red galaxy. It resides at the center of the galaxy cluster WHL J160319.0+031645 as the brightest cluster galaxy, with at least 114 confirmed member candidates. Its nucleus is active and classified as a Fanaroff-Riley Class Type II radio galaxy. The NRAO VLA Sky Survey measured a radio flux density of 127.00 mJy at 1.4 GHz. A 2022 study identified it as a bent-tailed radio galaxy, specifically a wide-angle tail type. The total flux density at 1.4 GHz is 132.94 mJy, and at 3 GHz it is 66.86 mJy, yielding a spectral index of 0.9α. A radio jet has a jet opening angle of 132.8° and a curvature radius of 30.8 arcseconds. The resolved radio lobes have a flux density of 0.128 Jy and are separated by 0.002°, while the radio core remains undetected. The largest angular size is 34 arcseconds, corresponding to a linear size of 126.0 kiloparsecs. The source is double, with an approximate bending angle of 41.3° and an excess bending angle of 34.4°.
