Young supernova remnants (YSNRs) are the most viable astrophysical laboratories for dust formation, and studies of these sources may explain the presence of huge quantities of dust observed in the early Universe. We propose to use IRAC, MIPS and IRS to observe a sample of six YSNRs: our sample includes sources located in a range of different interstellar environments and produced by both Type Ia and II supernovae. The goals of the proposed research include (i) searching for dust formed in the ejecta of YSNRs and measuring dust injection rates for different types of SNe, (ii) revealing dust structure through imaging at high angular resolution to help probe the onset and physical conditions of dust formation in YSNRs, (iii) using spectroscopy to probe dust composition and search for the missing Fe mass (as predicted to exist by nucleosynthesis models), and (iv) to study relativistic particle acceleration by YSNRs.
