多波段观测低及高红移尘埃星形成
摘要
本文探讨了如何从高红移星系可达波段光度的少数部分中了解高红移星形成情况。我们审查并量化了局部宇宙中星际灰烬产生的全光度与星系在紫外、中红外、亚毫米和射电波段光度之间的经验关联。这些关联表明，对高红移星系在任一波段的观测都应将其星形成率限制在 0.2--0.3 dex 范围内。我们汇集了高红移星系遵循这些局部标定关联的有限证据。本文综述了在 z ~ 0、z ~ 1 和 z ~ 3 时星系的特征光度及尘埃遮蔽情况。After discussing the relationship between the high-redshift populations selected in surveys at different wavelengths, we calculate the contribution to the 850um background from each. The available data show that a correlation between star-formation rate and dust obscuration L_dust/L_UV exists at low and high redshift. This correlation plays a central role in the major conclusion of this paper: most star formation at high redshift occurred in galaxies with 1 < L_dust/L_UV < 100 similar to those that host the majority of star formation in the local universe and to those that are detected in UV-selected surveys.

Existence of extremely obscured galaxies more clearly acknowledged. Original conclusions reinforced by the observed correlation between bolometric luminosity and dust obscuration at 0<z<3
