    #merger? z values indicate relatively close?

    Are you looking at SkyServer for the redshift?

  • lboynton by lboynton

    Yes, Photo Z. Correct?

    Where about on Skyserver? There are several 'z' values that are not actually redshift values 😕

    top right?

    Aahh, I see where you are looking! Very rough estimate, with no spectra to back it up, very unreliable. I do think it is a merger...

    ... from visual observation. I guess I don't need to say this, but Skyserver can sometimes be incorrect 😃

    Or overlay? Sorry, haven't been around since Zoo #1, lots of spectra data then. 😉

    No worries! There is still loads of spectra available on SkyServer, but sadly not for these galaxies! 😃 I will keep digging...

    Thanks, good to know about the z values. Are big z values still used to identify quasars?

    Not really 😃 more about the emissions themselves. I am not a spectra expert - prefer GL modelling. For spectra @budgieye 😃
