Radio/IR

• by VoyagerST

  I noticed that the blob in the center (pardon 'blob.' I just started doing this and am a little confused) is only visible in radio and the blob above and to the right a little is only visible in IR. Is this normal? If it is, what causes it? Thanks!

  Never mind. Like I said, I'm new to this and I realized that that happened to all the blobs.

  Hi VoyagerST,
  This can happen to very distant/ high redshift objects whereby the host galaxy is too faint to be observed in the infrared. Hope this helps.
  cheers,
  Ivy
