Abstract

Knowledge of the THz–IR optical properties of astrophysical ices is important for modeling the dust continuum emission and radiative transfer in dense and cold interstellar environments. The absence of such knowledge humpers analysis of modern astrophysical observations. To mitigate this difficultly, the experimental setup was developed to grow astrophysical ice analogues at cryogenic temperatures and then measure their broadband response using the THz pulsed spectroscopy and Fourier-transform IR spectroscopy. This setup was applied to study different ices: CO, CO2, N2, and H2O in the Ih, Ic, and amorphous phases.
