Scientific paper

We will use the PR110L prism on the SBC of ACS to map the FUV evolution of Type IIn supernovae SNe. The main goal of this proposal is to measure the FUV continuum, Ly-a emission line flux, and their evolution to 1 quantify and interpret Type IIn SN transient event detections at high redshift and 2 dramatically improve current high redshift Type IIn selection criteria. We show that the inherent properties of Type IIn SNe facilitate high redshift detection. We will observe the rest-frame FUV of a sample of eight 0.02 < z < 0.33 Type IIn SNe to directly measure the survival of Ly-alpha photons in low to intermediate redshift Type IIn SNe environments and extrapolate the results to high redshift. We will calibrate relationships such as FUV luminosity vs. emission line flux and measure emission line evolution vs. FUV light evolution. The intent is to categorize and improve the utility of Type IIn SNe.;
