Astro-H/SXS Science Objectives
|Science Area||SXS Questions||Sources||SXS Observations||Powerpoint info|
|Galaxy Formation and Evolution||How do structures such as galaxies and clusters of galaxies form and evolve? How do they create and disperse metals?||Galaxies and clusters of Galaxies, Diffuse Galactic Emission, Supernova Remnants and the ISM||Measurement of line strengths and velocities to derive chemical abundances, thermal state, turbulence and wind properties||Cluster Abundances, Elliptical Galaxies, Starburst Galaxies, ISM, Supernova Remnants, Feedback|
|Matter in Extreme Environments||How do supermassive black holes feed back energy into galaxies and clusters? How do neutron stars and white dwarfs accrete and eject material?||Active Galactic Nuclei and other Supermassive Black Holes, X-ray Binaries, Cataclysmic Variables||Black hole and accretion disk dynamics using Fe emission and absorption features.||Active Galactic Nuclei, X-ray Binaries, Cataclysmic Variables|
|Cosmology||What is the nature of dark matter and dark energy?||Clusters of Galaxies, Type Ia precursors and remnants||Use line diagnostics and velocity maps to calibrate cluster masses for cosmological models. Find mass of Type Ia progenitors via redshift of Fe K lines.||Cluster Survey, Type Ia Progenitors and Remnants|
