Euclid: Searching for pair-instability supernovae with the Deep Survey

Frédéric Courbin, Georges Meylan, Giovanni Longo, Yi Wang, Richard Massey

Pair-instability supernovae are theorized supernovae that have not yet been observationally confirmed. They are predicted to exist in low-metallicity environments. Because overall metallicity becomes lower at higher redshifts, deep near-infrared transient ...
