Type Ia supernovae (SNe Ia) are believed to result from the explosion of a carbon-oxygen white dwarf, induced by interaction with a binary companion. Spectroscopy of SNe Ia offers clues to the explosion properties from the composition and velocities of the SN ejecta...

While telescopes have been capable of capturing a single “picture” of the sky for quite some time, the high demand for the use of world-class facilities and historically limited fields of view on offer meant that repeat observations of the same areas of sky were...
