Fig. 4


Observed spectral energy distributions (SED) of galaxies with W1 − W2  >  2 mag, which include SDSS optical spectra (black solid lines) and WISE MIR photometric data in all four bands (red symbols and solid lines). For comparison in all panels are shown MIR SEDs for the “active” BCD SBS 0335–052E (red dotted lines) and for the “passive” BCD I Zw 18 (blue dashed lines).
