... The absence of galaxies with metallicities close to the one determined for I Zw 18 (1/50 Z ) is still a puzzling matter in BCGs research and the different explanations for the lack of these galaxies in the local Universe constitute a matter of debate. ...
... Especially for BCGs of extremely low chemical abundances which seems to be very rare objects in the local universe after all we learned so far, a coverage of several 10 3 square degrees down to the technical limits of the surveys is essential. ...
