摘要
XMM-Newton 和 Chandra 的 R~300-1000 衍射光谱 represent a radical advance, allowing spectroscopic physics techniques to be applied to X-ray astronomy, revolutionizing a wide range of research. Ten years on these spectra will be routine, and higher resolution will be needed. I propose ``Thermal Limit Spectroscopy'' as the next natural goal for X-ray spectroscopy. This will open up new physics: plasma physics, velocity widths, Doppler shifts, line profiles, and absorption lines in photoionized plasmas. A resolution of R=3000-10,000 is required, and the technology is within reach.
