Samenvatting
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.
