Abstract (from CDS):

We present 74-MHz data of 365 B3VLA sources, which were obtained as a by-product of the observations of Tschager et al. (2003A&A...402..171T) who observed a large area of sky with the VLA in A-array. Apart from the lowest-frequency observations of B3VLA sources performed so far contributing to our on-going multi-frequency study of this survey, these A-array data also provide the first morphological information at this low frequency. The most intriguing result is the discovery of two new Giant Radio Galaxy candidates, B31232+397B at a redshift of 3.22 and B31419+419 at a redshift of 0.367. This means that B31232+397B would be the most distant GRG known to date. At the same time, these two objects are two new examples of sources with recurrent activity. Our results give a foretaste of the impact which extremely low-frequency radio continuum observations will have for the study of source evolution.
