Abstract
The Sub-Lyman α Explorer (SubLymE) will be proposed to NASA as a Small Explorer mission in response to the anticipated Announcement of Opportunity in fall 2014. It will provide multi-color imaging in the 102 – 120 nm spectral window with 2 arc second resolution and a field of view 12 arc minutes in diameter. No astronomical imaging has been done in this bandpass previously. SubLymE will enable a host of previously impossible astronomical observations but its optical design and operational planning have been optimized around two key projects. 1: The mission will perform a survey of local galaxies, identifying and characterizing the youngest and most massive stellar clusters in local star-forming and star-bursting galaxies. These stellar clusters drive the physical and chemical evolution of galaxies like the Milky Way. 2: SubLymE will directly measure the amount and spatial distribution of ionizing photon escape from star-forming galaxies in the local universe (0.22 < z < 0.5), a critical measurement for understanding how the intergalactic medium was ionized during the epoch of reionization. We present the current optical design and predicted performance for SubLymE, and summarize its primary science objectives.
