Abstract

We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal. Its key specifications are: a large field of view (FoV) of 4.2 square degrees and a high multiplex capability, with 1624 fibres feeding two low-resolution spectrographs ($R = \lambda/\Delta\lambda \sim 6500$), and 812 fibres transferring light to the high-resolution spectrograph ($R \sim 20\,000$). After a description of the instrument and its expected performance, a short overview is given of its operational scheme and planned 4MOST Consortium science; these aspects are covered in more detail in other articles in this edition of The Messenger. Finally, the processes, schedules, and policies concerning the selection of ESO Community Surveys are presented, commencing with a singular opportunity to submit Letters of Intent for Public Surveys during the first five years of 4MOST operations.

most:项目概述和第一次征集方案的信息

我们介绍了4米多目标光谱望远镜(4MOST)，这是一种新型的高复用、宽视场光谱测量设备，正在为帕拉纳尔的4米可见光和红外天文测量望远镜(VISTA)开发。它的关键规格是:4.2平方度的大视场(FoV)和高复用能力，1624根光纤馈送两个低分辨率光谱仪($R = \lambda/\Delta\lambda \sim 6500$)， 812根光纤将光传输到高分辨率光谱仪($R \sim 20\,000$)。在描述了仪器及其预期性能之后，简要概述了其操作方案和计划的4MOST联盟科学;这些方面在本期The Messenger的其他文章中有更详细的介绍。最后，介绍了有关ESO社区调查选择的流程、时间表和政策，首先是在4MOST运营的前五年提交公众调查意向书的唯一机会。
