Novae may also have significant non-thermal emission from gamma-ray to radio wavelengths, produced by shocks. In the classical nova V959 Mon, the internal shocks, formed by a slow flow in the orbital plane and a fast flow in the polar direction, have been directly revealed by our multi-resolution and multi-band radio observations. To test if the two-flow model can explain the non-spherical geometry and non-thermal emission from all novae, we have already submitted a ToO proposal (proposal code: RSY06) to search for compact knots in the gamma-ray detected Nova V392 Per. On condition that some non-thermal compact knots are clearly detected in the EVN ToO and VLBA observations, we request to add another 16-hour e-EVN experiment at 1.6 GHz to provide the most complete view of these fading compact knots at a later stage. With the much larger beam area, the 1.6-GHz EVN image on 2018 Sep 19-20 will allow us to reveal both long-lived and newly-emerged compact knots and directly compare them with the thermal emission structure observed by the e-MERLIN on a scale of ~100 mas.
