The population of intermediate-mass black holes (IMBHs) in nearby dwarfgalaxies plays an important "ground truth" role in exploring black holeformation and growth in the early Universe. In the dwarf elliptical galaxy SDSSJ090613.77+561015.2 (z=0.0465), an accreting IMBH has been revealed by opticaland X-ray observations. Aiming to search for possible radio core and jetassociated with the IMBH, we carried out very long baseline interferometry(VLBI) observations with the European VLBI Network (EVN) at 1.66 GHz. Ourimaging results show that there are two 1-mJy components with a separation ofabout 52 mas (projected distance 47 pc) and the more compact component islocated within the 1-sigma error circle of the optical centroid from availableGaia astrometry. Based on their positions, elongated structures and relativelyhigh brightness temperatures, as well as the absence of star-forming activityin the host galaxy, we argue that the radio morphology originates from the jetactivity powered by the central IMBH. The existence of the large-scale jetimplies that violent jet activity might occur in the early epochs of black holegrowth and thus help to regulate the co-evolution of black holes and galaxies.
