Reference Brinchmann 2024). Thus, degeneracies between redshift, galaxy type, and S/N constraints add uncertainty to the determination of ...
JWST’s Newfound Galaxies Are the Oldest Ever Seen
WebAbstract. Abstract Double source lensing, with two sources lensed by the same foreground galaxy, involves the distance between each source and the lens and hence is a probe of the universe away from the observer. The double source distance ratio also reduces sensitivity to the lens model and has good complementarity with standard distance probes. WebMay 14, 2024 · Perhaps the highest-redshift galaxy detected by Spitzer so far is a lensed galaxy. In ref. 35, the authors reported the detection of MACS0647-JD, a z ≈ 11 galaxy candidate strongly lensed...
