Galaxies are the most obvious tracers of large-scale structure in the Universe, and understanding how they emerge and evolve throughout cosmic history has been a longstanding goal of cosmology and astrophysics. The CDM paradigm approaches this via the gravitational collapse of dark matter haloes from an initial quasi-homogeneous Universe.

Evolved very massive and low-metallicity stars (with zero-age-main-sequence mass ⁠, and metallicity ⁠) are predicted to end their lives in a pair-instability supernova (PISN), where the star is disrupted completely, leaving no remnant (e.g. Fowler & Hoyle 1964; Barkat, Rakavy & Sack 1967). These events eject a large amount of material and energy into the environment, enriching galaxies with more massive elements (Langer 2012).
