The study examines the galaxy VV 340a, which hosts an active galactic nucleus with a low-power jet emanating from the supermassive black hole at its center[4][5][6]. The stream precesses with a period of (8.2 ± 5.5) × 10^5 years and drives gas outflow at a rate of 19.4 ± 7.9 solar masses per year[4][5][6][8]. The shocks caused by the jet create a highly ionized plasma that extends several kiloparsecs from the galactic core[4][5][6]. Radio data reveal a spiral, S-shaped stream pattern on kiloparsec scales, the first observed precessional radio stream in a disk galaxy[7][9]. The outflow expels enough gas to affect the star formation rate of the galaxy[4][5][6][7]. Observations include optical, infrared, submillimeter and radio wavelengths[4][5][6]. These findings help to better understand the feedback mechanisms of the active galactic nucleus on galaxy evolution[4][5].
