Structure of the Radio Sources 3C 46, 66, 129 and 465

3C 129: The GMRT observations

“…Head-tail radio sources, which are almost always associated with clusters of galaxies, are characterised by a highly elongated radio structure with the associated optical (usually giant elliptical) galaxy at one end. A classical example of this class is 3C 129 which, along with its companion 3C 129.1 (a wide-angle-tail), is a member of the X-ray cluster 4U 0446+44 (z = 0.021) that happens to lie in the galactic plane (b = 0 • .5, l = 160 • ) (Macdonald et al 1966, Hill & Longair 1971. 3C 129 is classified as a prototype narrow-angle-tail (Lane et al 2002) and has a total flux density of ∼6.27 Jy at 1400 MHz (Bologna et al 1969).…”

Lines of Galaxies from Radio Sources

“…308 (Arp 1966a); and a photograph if NGC 541, which is the adjoining galaxy southwest along this line, is found in Atlas 133. The center of this line of galaxies is shown well in Maltby, Matthews, and Moffet (1963), where it is seen that the next galaxy immediately southwest of NGC 541 along the line is a lenticular galaxy oriented almost exactly along the line. Zwicky has reported the presence of a luminous bridge running along this line of galaxies (Maltby, Matthews, and Moffet 1963), but limiting exposures by Arp (unpublished) do not reveal, at least by visual inspection, any obvious luminous material along this line.…”

“…The structure of the radio source involved with 3C 270 is well known (Maltby, Matthews, and Moffet 1963). The angular separation of the two radio lobes is 4'7 in roughly an east-west direction.…”

“…Minkowski (private communication) indicates, however, that there is a third radio component involved with 3C 40, so the situation with respect to the alignment of radio components is unclear at this time. The value for the redshift of NGC 545-7 quoted in Maltby, Matthews, and Moffet (1963) is 5320 km/sec. Zwicky (unpublished) has further redshifts in this group.…”
