近紫外线Spectroscopy与VLT

Near-UV Spectroscopy with the VLT

Rodolfo Smiljanic

摘要:

39米的欧洲极大望远镜(E-ELT)预计在可见光谱的蓝色部分具有非常低的吞吐量。正因为如此,8米超大望远镜上的蓝色优化摄谱仪可能在波长小于400 nm的情况下与E-ELT竞争。2012年完成了关于这一文书的概念研究。这将是一个高通量、中等分辨率(R $\sim$ 20\,000)的光谱仪,在300和400 nm之间工作。目前预计,该仪器的建设将在今后几年内开始。在这方面的贡献,我提出了一个总结的仪器概念和一些可能的银河系和河外科学的情况下,激励这样的摄谱仪。

英文摘要:

The 39-meter European Extremely Large Telescope (E-ELT) is expected to have very low throughput in the blue part of the visible spectrum. Because of that, a blue-optimised spectrograph at the 8-meter Very Large Telescope could potentially be competitive against the E-ELT at wavelengths shorter than 400 nm. A concept study for such an instrument was concluded in 2012. This would be a high-throughput, medium resolution (R $\sim$ 20\,000) spectrograph, operating between 300 and 400 nm. It is currently expected that construction of this instrument will start in the next few years. In this contribution, I present a summary of the instrument concept and of some of the possible Galactic and extragalactic science cases that motivate such a spectrograph.
