SDSS J172513.00+392305.1 Giant candidate?

  • sisifolibre by sisifolibre

    Looking in the ARG0001723 NVSS field I have found this:

    enter image description here

    I think that there are a triple to the NW. I have make a overlay to search the host and seems to be SDSS J172513.00+392305.1. But I couldn't found an ARG field which content it, here in the forum or in the ARG list of fields. (this has caused me a little headache)... 😦. May be this is because in FIRST the radio emission looks very weak.

    SDSS J172513.00+392305.1

    Sorry, I haven't been able to do a better overlay 😦. Red lines are NVSS contours, blue lines are FIRST contours

    enter image description here

    If I am right, and SDSS J172513.00+392305.1 is host of a triple with 4.946' and photometric redshif 0.256 is a giant candidate of 1.18Mp

    But may be I,m wrong in all! XD

    Yes, a giant candidate

    IMHO Size ~4.75' ; ph_z = 0.256 , z_sp per NED is 0.289800; ~1.1Mpc ; ~1.22 for z_sp

    Yes, host is SDSS J172513.00+392305.1 aka B3 1723+394

    But I couldn't found an ARG field which content it,

    Looks like there is none, ARG00016zs is as close as you can get

    see 2001A&A...371..445M and 2006A&A...454...85M

    Good catch, anyway , keep up the good work!
