| 内容記述 | A complete observational understanding of the first stars and galaxies will require four facilities: JWST, 30m ground-based telescopes, ALMA, and the SKA. Each provides complementary capabilities. JWST is our best hope for looking to very high redshift. 30m-class ground-based telescopes provide sensitivity to the rest-frame ultraviolet with high-resolution imaging and high-resolution NIR spectroscopy, possibly reaching as far as z approx.15. They will also allow us to study stellar populations in nearby galaxies and examine the fossil record of the first stars. ALMA will image the redshifted dust continuum emission from evolving galaxies out to z approx.10. The SKA will do cosmic tomography, mapping the process of reionization. |
