论文摘要
尖端多对象光谱仪与世界最大的望远镜ELT的强大组合将使我们能够对宇宙更深入地探查宇宙。马赛克是为宇宙中众多微弱来源提供光谱的极其有效的工具，包括宇宙电离的第一个星系和源。除了NIR中的多综合场单元（多IFU）外，Mosaic在NIR和VIS中具有高的多路复用。因此，非常适合在银河光环中的Z = 3-4中进行暗物质（从旋转曲线）和Baryons的库存。马赛克将在z = 3时启用二层次培养基的详细图，这是哈勃时期矮星系的进化史，化学反应直接从恒星直接测量到几个MPC。最后，它将测量在集群重力镜片中看到的所有微弱特征，或者在附近银河系光环周围的溪流中看到，使马赛克成为一种强大的仪器，并具有很大的发现空间。马赛克的初步设计预计将于明年开始，鉴于团队的乐器研究，其准备水平已经很高。
The powerful combination of the cutting-edge multi-object spectrograph MOSAIC with the world largest telescope, the ELT, will allow us to probe deeper into the Universe than was possible. MOSAIC is an extremely efficient instrument in providing spectra for the numerous faint sources in the Universe, including the very first galaxies and sources of cosmic reionization. MOSAIC has a high multiplex in the NIR and in the VIS, in addition to multi-Integral Field Units (Multi-IFUs) in NIR. As such it is perfectly suited to carry out an inventory of dark matter (from rotation curves) and baryons in the cool-warm gas phases in galactic haloes at z=3-4. MOSAIC will enable detailed maps of the intergalactic medium at z=3, the evolutionary history of dwarf galaxies during a Hubble time, the chemistry directly measured from stars up to several Mpc. Finally, it will measure all faint features seen in cluster gravitational lenses or in streams surrounding nearby galactic halos, providing MOSAIC to be a powerful instrument with an extremely large space of discoveries. The preliminary design of MOSAIC is expected to begin next year, and its level of readiness is already high, given the instrumental studies made by the team.
