WISE color–color plot. Photometric ratios in magnitude (mag) between three IR bands (W1_3.4 μm, W2_4.6 μm, W3_12 μm, with W1–W2, W2–W3). Black markers correspond to dwarf galaxies matched to a compact radio source with luminosity exceeding 3σ in the L–SFR relation. Gray-filled markers indicate dwarf galaxies matched to a radio source. We demarcate the two sources falling within the AGN region (Jarrett et al. 2011) marked by dashed lines within our sample as being classified.
