AGEL Survey Data Release 2: Expanding the Gravitational Lens Frontier

Sample HST image DESJ2125-6504

The AGEL Survey team has just announced their second major data release—AGEL DR2—unveiling 138 confirmed strong gravitational lenses, up from 77 in their 2022 release. This diverse sample spans galaxy-scale to group and cluster lenses, including striking Einstein rings and rare systems like double-source plane lenses, which are especially valuable for cosmology.

These lenses were first flagged by machine learning in DES and DECaLS imaging, with an impressive 96% confirmation rate from follow-up spectroscopy. Notably, AGEL lenses are pushing the envelope with higher-redshift deflectors and sources, opening new windows into galaxy evolution and dark matter studies.

This release also includes high-resolution Hubble imaging for 71 lenses—offering stunning detail
