Gravitational lensing: candidates outside the CFHTLS Wide Field

  • c_cld by c_cld

    In GalaxyZooforum reply 7105 on: February 07, 2014, I've reported a spectroscopic candidate SDSS J141531.22+111207.7 1237661950266966223 z lens 0.315 zsource=1.145.

    1237661950266966223 1237661950266966223

    Now, I report a newly discovered lensed QSO SDSS J164045.57+193255.2 1237662225166959350 z_spec=0.778 as an arc around the elliptical SDSS J164045.66+193257.1 1237662225166959349 z_spec=0.195

    12376622251669593497 1237662225166959349

    A possible counter image of the curved QSO is 1237662225166959351 with Image Separation of 4.785 Arcseconds 😃

    Elliptical lens spectrum:

    next QSO reddish spectrum!

    Both were imaged by DECaLS

    Maybe useless, but residuals look interesting

    SDSS J141531.22+111207.7 probaly imaged in single band for now

    Thanks Edd for posting MegaPipe image cutouts.

    My selection is based on some of my data mining of luminous red galaxies (LRG) and eyeballing the output:

    first testing on a selection of known lenses by SDSS spectra

    and then applying the queries to "boss" spectra in cas jobs

    further reducing ~130K objects to ~20K for looking at in "chart" 😃
