Scientific paper

We examine the faint-end slope of the V-band luminosity function, to M < -14, of strongly star-forming galaxies of galaxy spectral type Scd and bluer with redshift z < 0.5, using a sample of 20,620 galaxies in the Cosmic Evolution Survey (COSMOS) field. The steepness of the faint-end slope for the redshift range 0.02 < z < 0.1 for these galaxies is α -1.05; it is sharply steeper, however (α -1.46), for galaxies of only the bluest starburst types. For the redshift range 0.1 < z < 0.5, the faint-end slope is consistent with, or slightly shallower than, these values. These results are consistent with previous studies of the luminosity function of strongly star-forming galaxies.
