摘要
背景:光学干涉测量正处于关键发展阶段。ESO 的 VLTI 已为长基线干涉测量建立了稳定、健壮的基础设施,供普通天文观测者使用。当前的第二代仪器提供了宽波长覆盖和改进的性能。其灵敏度和测量精度带来了高可靠性的数据与图像。目标:我们研制了 MATISSE(多孔径中红外光谱实验),以在宽光谱域获取高分辨率成像,并探索如下课题:恒星活动与质量损失;年轻恒星周围气体与尘埃盘中的行星形成与演化;活动星系核(AGN)中超大质量黑洞周围的吸积过程。方法:该仪器是一台光谱干涉成像仪,覆盖 L、M、N 三个大气波段(2.8 至 13.0 mu),组合来自 VLTI 望远镜的四束光。其概念、相关观测流程、数据缩减与定标方法源自 30 年的仪器研究。仪器采用多轴光束组合以产生光谱色散条纹。信号在多种光谱分辨率下提供以下量:测光流量、相干流量、可见度、闭合相位、波长差分可见度与相位,以及孔径合成成像。结果:我们概述了仪器的物理原理及其功能、输出信号的特征、观测模式及其性能极限的描述。一组数据和重建图像展示了首批获取的关键观测。结论:该仪器自 2018 年起在智利 ESO 帕瑞纳山运行,并自 2019 年 4 月起对国际学界开放科学使用。首批科学结果目前正在发表。
