19 Mar 2003 | | Subject: | astro-ph | | Affiliation: | Harvard-Smithsonian Center for Astrophysics; Osservatorio di Roma, Monteporzio | | Abstract: | We present a mission concept for high resolution X-ray spectroscopy with a resolving power, R~6000, (c.f. R=<1000 for Chandra, XMM-Newton). This resolution is physics-driven, since it allows the thermal widths of coronal X-ray lines to be measured, and astrophysics-driven, since 50 km/s resolves internal galaxy motions, and galaxy motions within larger structures. Such a mission could be small and have a rapid response allowing us to `X-ray the Universe’ using the afterglows of Gamma-ray Bursts (GRBs) as strong background sources of X-rays, and so illuminate the `Cosmic Web’. The Cosmic Web is predicted to contain most of the normal matter (baryons) in the nearby Universe. | | Source: | arXiv, astro-ph/0303444 | | Services: | Forum | Review | PDF | Favorites | |
