Dual AGN are important for understanding galaxy-merger-triggered fueling of black holes and hierarchical growth structures. The least explored type dual those associated with mergers two dwarf galaxies. According to observations cosmological simulations, galaxies the most abundant in early Universe galaxy merger rate is dominated by dwarfs. However, these generally too distant be directly obser...
