AB  - Context. All galaxies without a radio-loud AGN follow a tight correlation between their global far-infrared (FIR) and radio synchrotron luminosities, which is believed to be ultimately the result of the formation of massive stars. Two colliding pairs...
AB  - Aims. We are aiming to clarify the origin of the radio continuum emission from the bridge.
AB  - Methods. The radio synchrotron emission expected from the bridge regions is calculated, assuming that the kinetic energy liberated in the predominantly gas dynamic interaction of the respective interstellar media (ISM) has produced shock waves that...
AB  - Results. We found that the nonthermal energy produced in the collision is high enough to explain the radio emission from the bridge between the two galaxies. The calculated spectral index at the present time also agrees with the observed value. The...
AB  - Conclusions. The deviation of these two interacting galaxy systems from the standard FIR-radio correlation is consistent with the acceleration of an additional population of electrons in large-scale shock waves resulting from the gas dynamic...
