4C 14.27 is notable for its very steep spectrum and lack of
a compact radio core: in our image
a red cross marks the position of the optical
galaxy. The brightness enhancement ("warm spot") at the end of the
shorter east lobe is too low-contrast to qualify as a
hotspot, so that lobe is
classified as "relaxed". All these symptoms suggest that the central
engine has temporarily switched off jet production, although strong
emission lines are still being produced by the AGN
(Jackson & Rawlings 1997)
4C 14.27 was added to the 3CRR sample by
Laing, Riley & Longair (1983) as its
flux in the more accurate 4CT survey was high enough that it should
have been included in 3CR. Mostly likely it was omitted simple due
to random errors in 3CR as it is very close to the minimum flux density
for inclusion.
