    I posted this in objects that need more research floortap, from tools: Absolute Size (kpc):27.65108....what does this mean?

    I will add it too the #lens collection so I can have a closer look when I have more time. It does look a bit arc like, but I have concerns.

    @ramberts - kpc (kilo parsec) is a unit of measurement, in this case it is the size / diameter of the galaxy.

    Thanks Capella, is a larger KPC an indicator that that a galaxy may be a lens candidate or is there a different size indicator you look for?

    1/2 No, not really. It is more the mass of the galaxy and not necessarily the size that determines lensing. Looking at the shape / colour...

    2/2 is more important when visually indentifying a lens candidate. Followed up by modelling and spectragraph.

    how can you tell mass...curious if there is an easy way 😃

    In a short answer, no. That is why lenses are so important - a lot of a galaxies mass is not visible, so we can only make estimates.
