Identified with the large elliptical galaxy
M 84 in the core of the
Virgo cluster,
3C 272.1 is the lowest-power DRAGN in our sample. Because of the
malmquist bias it is much
more representative of the "typical" DRAGNs than the other members of the
sample. It is quite small, comperable in size with the observed optical and
X-ray diameters of M 84, consistent with the general correlation between
size and power in FR I DRAGNs
(Fanti et al. 1987).
Laing & Bridle mapped the
Faraday Rotation across this object and
showed that the rotation is due to gas in front of, but not mixed with,
the radio lobes. This gas is visible in soft X-rays
(Forman, Jones & Tucker 1984). The
Chandra X-ray Observatory has shown that the radio lobes occupy
low-density regions surrounded by higher-density X-ray emitting filaments
(Finoguenov & Jones 2001).
The Other Images pages has higher resolution images of the central jets.
See Alan
Bridle's image gallery for more versions of the radio images, with
overlays on sky survey and HST images.
