Emission line flux limits in four QSO metal line absorbers.

Abstract (from CDS):

In an effort to detect the early phases of star formation in massive galaxies, we have searched for Lyα and [OII]λ3727 emission from four QSO metal absorption line systems and possible associated galaxies, using narrow-band filters. None of the objects was detected. We discuss the possible effects of dust on the visibility of the objects and show that we can derive interesting upper limits on the star formation rates.
