Abstract
We present and discuss the second list of the Montreal Blue Galaxy sur vey. Following the inspection of 71 plates, we found 237 new candidate s with B<15.5. 73 percent of them are also detected by IRAS. Spectroph otometry was carried out, at medium resolution, for a subset of 40 obj ects leading to the identification of three new AGNs and producing 13 new radial velocities. Spectral. classification of our candidates conf irms our previous finding that the majority of our candidates are star burst nucleus galaxies similar to the objects studied by Balzano [ApJ, 268, 602 (1983)]. Our survey is biased against the high excitation st arburst H II galaxies and the LINER galaxies. Metallicities of our gal axies are found to be from log (O/H)=8.4 to 9.0, which suggests galaxi es in advanced stages of chemical evolution.
