Science with IXO

Science with IXO

Overview

NOTE: In March 2011 ESA announced a new way forward for the L-class candidate missions: IXO, EJSM-Laplace and LISA.
At this time the IXO concept ceased to be a candidate and ESA, along with the scientific community, is now investigating to what extent a European-led mission could preserve the original science case of IXO. The new study is called ATHENA (Advanced Telescope for High ENergy Astrophysics).

The ATHENA assessment study report (Yellow Book) is now available.

The International X-ray Observatory (IXO) is a next-generation facility designed to address some of the most fundamental questions in contemporary astrophysics and cosmology. Building on the accumulated knowledge acquired by the current (and previous) X-ray facilities IXO will address these primary goals:

  • Black holes and matter under extreme conditions
  • Formation and evolution of galaxies, clusters and large scale structure
  • Life cycles of matter and energy

IXO will provide the advances in X-ray imaging, timing and spectroscopy needed to address these goals.

The IXO optics will have 20 times more collecting area at 1 keV than any previous X-ray telescope. The focal plane instruments will deliver up to 100-fold increase in effective area for high resolution spectroscopy from 0.3-10 keV, deep spectral imaging from 0.2-40 keV over a wide field of view, unprecedented polarimetric sensitivity, and microsecond spectroscopic timing with high count rate capability.
