IC 3639

IC 3639 has a NIR bar aligned at P.A.=1508#8 (Mulchaey et al 1997). In the digital sky survey IC 3639 has two companions: a ring galaxy 1.8 arcmin (22 kpc) to the North-East, and an edge-on galaxy 2.6 arcmin (33 kpc) to the North-West. The radio map at 20 cm shows a strong core embedded in diffuse emission, but at 6 cm only the core is detected (Ulvestad & Wilson 1989). The excitation ratio [OIII]/H10#10 is equal to 7.8 (Whittle 1992b), and conspicuous [NeV] and HeII is also present.
