Astro2020 Science White Paper: Are Supernovae the Dust Producer in the Early Universe?

Whether supernovaeare a significant source of dust has been a long-standing debate. The large quantities of dust observed in high- redshiftgalaxies raise a fundamental question as to the origin of dust in the Universe since stars cannot have evolved to the AGB dust-producing phase in high- redshiftgalaxies. In contrast, supernovaeoccur within several millions of years after the onset of star formation. This white paperfocuses on dust formation in supernova ejectawith US-Extremely Large Telescope (ELT) perspective during the era of JWST and LSST.
