Radio emission from 23 tidal disruption event host galaxies were searched in
the 144 MHz LOFAR-LoTSS2 images. Three host galaxies are detected with diffuse
radio emission, which can be interpreted as either galactic synchrotron radio
emission or diffuse radio halo in dense galactic environments. Non-detection of
(transient) radio emission in majority of galaxies could be due to
self-absorption of radio emission associated with the tidal disruption event.
The detected objects are AT2018iih, RBS 1032, and NGC 5905. Non-detection for
Sw 1644+57 is also reported.
