Cosmic dust can have crucial effects on the light from distant objects such as gamma-ray bursts and supernovae. Using astrophysical data, models of dust production, and laboratory dust measurements the properties of cosmic dust will be inferred and used to interpret the light from cosmic lighthouses.
DARK studies early dust production and modification by massive stars, supernovae, and quasars, theoretically and observationally addressing the nature and effects of the first dust grains and their epoch of formation. We will determine the properties of dust in differing environments and study the role and nature of dust obscuration for the cosmic star‐formation rate. Our goal is to carry out a well‐constructed theoretical effort, examining the formation and destruction of dust in the early universe to be expected from different stellar sources at different metallicities.
