There are several compact background sources projected in and around this large DRAGN; the true core is the point source near the centre of the image, between the two filaments that cross the central gap.
Apart from the core, there are no high-brightness compact features in the DRAGN, hence the classification as a relaxed double (RD). We have added the suffix "pec" for peculiar, because of the filaments. These cannot be jets, as they do not emanate from the core; at present we do not understand how such filaments are formed.
This main Atlas image is a smoothed version of the original VTESS image,
which is available on the "other images" page. The original shows
more details but also some weak
artifacts in the form of low-level
stripes.
