Gravitational lensing: candidates outside the CFHTLS Wide Field
-
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.
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
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
Image from DECaLS (left) / residuals (right)
SDSS J141531.22+111207.7 probaly imaged in single band for now
SDSS J164045.66+193257.1
Both were imaged by CFHT, but data behind the password 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" 😃

I will try to compile a list for beginning
