Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky

Rémy Elie Joseph, Cameron Alexander Campbell Lemon, Johan Richard, Johannes Richard Cornelis Geerit Kruis

Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a stellar explosion in a distant galaxy and observing it through a nearly perfe ...
