Tales of radio tails behind Jellyfish galaxies in the Coma cluster

Ram pressure stripping is an important process to study galaxy evolution. The stripped tails have been shown to be multi-phase and forming stars. As energy transfer in multi-phase medium is an outstanding question in astrophysics, important for e.g., galaxy formation and AGN feedback, the stripped tails provide great examples to address the significant questions in multi-phase medium. We present continuum and HI results from new JVLA L-band observations of two fields in the Coma clusters. Our new data, in the B configuration, are much deeper than the previous ones. Over 2000 radio continuum sources are detected and the source density in the central 6.4' radius is 4.6 - 8.0 times the previous one from Miller et al. (2009). For the first time, radio continuum emission is detected in stripped tails, unambiguously revealing the existence of magnetic field in the tails. The radio spectra generally steepen away from the galaxy. We also present HI detections in two Jellyfish galaxies. The implications of our new radio results on stripped tails will also be discussed.
