Scientific paper

We have made a radio and optical study of the radio source PKS 0241+011 associated with a quasar at z = 1.40. In earlier radio maps this source appears as a large triple radio source with an angular extent of 400 arcsec (2.4h(-1) Mpc; H_0 = 100h km s(-1) Mpc(-1) , q_0 = 0.0). If the triple radio structure seen in radio maps represents a single object, PKS 0241+011 would be the largest radio quasar observed so far. We present new radio and optical data, which reveal that this source actually consists of three separate sources. The radio source associated with the z = 1.40 quasar has a linear extent of 65h(-1) kpc.
