We report on the serendipitous discovery of an unprecedented interaction
between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was
made thanks to LOFAR observations at 144 MHz of the galaxy cluster Abell 160
(z=0.04317) provided by the LOFAR Two-metre Sky Survey. The new low-frequency
observations revealed that one of the radio plumes of the central galaxy GIN
049 overlaps with the spiral galaxy JO36. Previous studies carried out with
MUSE revealed that the warm ionized gas in the disk of JO36, traced by the
Hα emission, is severely truncated with respect to the stellar disk. We
further explore this unique system by including new uGMRT observations at 675
MHz to map the spectral index. The emerging scenario is that JO36 has
interacted with the radio plume in the past 200-500 Myr. The encounter resulted
in a positive feedback event for JO36 in the form of a star formation rate
burst of ∼14M⊙ yr−1. In turn, the galaxy passage left a trace
in the radio-old plasma by re-shaping the old relativistic plasma via magnetic
draping.Comment: 20 pages, 11 figures. Accepted for publication on ApJ on September
