Lens or arc. Is that correct ?

• by LiradeTerpsichore

  Hello everybody, I'm new here, and finding out how it works.
  I would like to know if in this case it is correct to choose no tidal debris, but yes: lens, arc.

  The curves are disturbed spirals arms or debris trails.

  Lensed galaxies are a different colour to the lensing galaxy, are curved, and are almost always around ellipticals which are bigger and make a bigger hole for the light to fall into. See the Spotter's guide in SpaceWarps http://spacewarps.org/#/guide
