2005A&A...435..863M Multi-frequency study of the B3 VLA sample IV. 74-MHz flux densities from VLA A-array data K.-H. Mack, M. Vigotti, L. Gregorini, U. Klein, W. Tschager, R. T. Schilizzi and I. A. G. Snellen Received 28 December 2004 / Accepted 15 February 2005 We present 74-MHz data of 365 B3 VLA sources, which were obtained as a by-product of the observations of Tschager et al. (2003, A&A, 402, 171) who observed a large area of sky with the VLA in A-array. Apart from the lowest-frequency observations of B3 VLA 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, B3 1232+397B at a redshift of 3.22 and B3 1419+419 at a redshift of 0.367. This means that B3 1232+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.
