The Strong Lensing Discovery Engine - Q1 missed targets

AstroVink-Q1: Strong gravitational lens candidates missed in Euclid Q1

This record contains newly identified strong gravitational lens candidates discovered with the AstroVink-Q1 vision-transformer network in Euclid Quick Data Release 1 (Q1). 

These systems were not included in the initial Strong Lensing Discovery Engine (SLDE) catalogues (see SLDE A and SLDE F) and were verified through Space Warps and expert inspection. The full method is described in

“Euclid Quick Data Release (Q1): AstroVink: A vision transformer approach to find strong gravitational lens systems.”
