Abstract
THE central region of M87 has a complex radio structure. There are at least three components1,2, with diameters ≈0″.0013, ≈0″.01 and ≈0″.3, coincident with the optical nucleus of the galaxy and on either side there are two elongated components, ≈25″ in extent, the radio counterparts of the jet and counterjet3,4. When observed with a resolution of ≈5″, the structure of these outer components is similar and depends little on observing frequency, but at higher resolutions the jet component is seen to possess fine structure which the other lacks5,6. Here I report results of interferometer observations at 408 and 1,666 MHz, with resolving powers ≈0.5″ along the jet, which reveal the position and extent of this fine structure in more detail.
