(亚)毫米波干涉测量的令人兴奋的未来:ALMA

The exciting future of (sub-)millimeter interferometry: ALMA

V. Casasola, J. Brand

摘要:

目前正在建造的阿塔卡马大型毫米/亚毫米阵列(ALMA)是一种革命性的天文干涉仪,将在(亚)毫米波长下工作。凭借前所未有的灵敏度,分辨率和成像能力,ALMA将探索(亚)毫米宇宙,天文学的最后前沿之一。ALMA有望提供早期宇宙中恒星和星系形成的洞察力,并对当地恒星和行星形成进行详细成像。ALMA调试和科学验证阶段目前正在进行中,为早期科学做准备。ALMA早期科学计划的呼吁预计将在2010年底前发布。在这篇文章中,我们将描述ALMA项目,阵列和它的接收器,它的科学目标,以及它的科学和技术潜力。我们将概述ALMA区域中心的组织结构,这些中心将在向用户提供支持方面发挥重要作用,特别关注意大利博洛尼亚ALMA区域中心。最后,我们将说明ALMA可以为AGN燃料的具体科学案例做出贡献。

英文摘要:

The Atacama Large Millimeter/submillimeter Array (ALMA), presently under construction, is a revolutionary astronomical interferometer, that will operate at (sub)millimeter wavelengths. With unprecedented sensitivity, resolution, and imaging capability, ALMA will explore the (sub-)mm Universe, one of astronomy's last frontiers. ALMA is expected to provide insight in star- and galaxy formation in the early Universe and to image local star- and planet formation in great detail. The ALMA Commissioning and Science Verification phase is currently in course, preparing the path for Early Science. The Call for ALMA Early Science proposals is expected to be released before the end of 2010. In this contribution we will describe the ALMA project, the array and its receivers, its science goals, and its scientific and technological potential. We will outline the organizational structure of the ALMA Regional Centres, that will play an important role in providing support to the users, with particular attention to the Italian ALMA Regional Centre in Bologna. Finally, we will illustrate what ALMA can contribute to the specific science case of AGN fueling.
