1.4-GHz Observations of Extended Giant Radio Galaxies.

WEZGOWIEC M., JAMROZY M. and MACK K.-H.

Abstract (from CDS):

This paper presents 1.4-GHz radio continuum observations of fifteen very extended radio galaxies. These sources are so large that most interferometers lose partly their structure and total flux density. Therefore, single-dish detections are required to fill in the central (u,v) gap of interferometric data and obtain reliable spectral index patterns across the structures, and thus also an integrated radio continuum spectrum. We have obtained such 1.4-GHz maps with the 100-m Effelsberg telescope and combined them with the corresponding maps available from the NVSS. The aggregated data allow us to produce high-quality images, which can be used to obtain physical parameters of the mapped sources. The combined images reveal in many cases extended low surface-brightness cocoons.
