Scientific Returns

The TTF Field Galaxy Survey aims to cover 0.56 on the sky ( Mpc), the returns from which we expect to be numerous. First, the survey promises unprecedented detection of H emission in the separate star-forming galaxy population at -- thereby providing a quantifiable and independent confirmation of its extent compared to the [OII] detections of recent spectroscopic surveys. Second, we expect to extend the current limits for detection of distant emission-line galaxies due to our low background advantage and high line/continuum ratio compared to broadband surveys. Finally, at we are probing for H emission from local counterparts to the FBGs; the results of which will provide much stronger constraints on the star-formation rates found at than has previously been possible.
