Hi gas in the rejuvenated radio galaxy PKS 2014–55
- Abstract:
- We present new high-spectral-resolution MeerKAT observations of absorption against the central region of the restarted, giant, X-shaped radio galaxy PKS2014–55, which exhibits morphological evidence of three distinct cycles of activity. We report a wide component (FWHM 38 7 km ) redshifted to 96 50 km , a deep-narrow detection (FWHM 19 6 km ) which is redshifted to 160 40 km, and a shallow component (FWHM 22 6 km) redshifted to 240 40 km . One of the three components exceeds the typical rotational velocity of 100 km , suggesting complex kinematics of the inflowing gas. These observations support the correlation between the occurrence of absorption and the rejuvenation of radio activity.
