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 |
