Is dark matter massive enough to cause lensing?

  • lamperti by lamperti

    This question arose in my mind since I've seen at least two images with a curvature of blue streaks resembling lenses but no central galaxy. I was wondering if I should mark them as such. I should have marked them as favorites so I would have a record, but will do so if I run across similar ones in the future.

    Sorry, I didn't understand your question earlier and that you were referring to -- whether dm alone is sufficient for causing lensing. In that case, please see a similar discussion here with some explanation - http://talk.spacewarps.org/#/boards/BSW0000002/discussions/DSW00005xd
