ARG0001q8q: overlapping #wat and #triple

• by JeanTate

  The host of the #wat to the E of center is hidden in the glare of a bright star; the host of the triple - whose N lobe overlaps with the WAT - is SDSS J161828.98+295859.6, which itself is overlap/merger, of stars and galaxies (?):

  S sources in ARG0000a92 also have an #overlap: main is a #triple, and SW lobe overlaps with a #compact.

  I wonder how common overlaps are?

  Hi @JeanTate, specifically for RGZ, it's very difficult to quantify how common overlaps are because of our initial sample selection. Perhaps papers like Kimball et al may try to estimate the prevalence of overlaps in the FIRST survey but it's typically a more difficult estimation with radio observations than optical studies due to the unknown number of radio components per host per redshift bin.

  Having said the above, this subject is gives us a view of a somewhat overdense region (ie. appears to be a cluster environment) so the probability of overlaps will be increased.
