Multiwavelength Astronomy and CTA: X-rays

Abstract We discuss how future X-ray instruments which are under development can contribute to our understanding of the non-thermal Universe. Much progress has been made in the field of X-ray Astronomy recently, thanks to the operation of modern X-ray telescopes such as Chandra , XMM- Newton , Suzaku , and SWIFT , but more in-depth investigation awaits future missions. These future missions include ASTROSAT , NuSTAR , e-ROSITA , ASTRO-H and GEMS , which will be realized in the next decade, and also much larger projects such as Athena and LOFT , which have been proposed for the 2020’s. All of those are expected to bring a variety of novel observational results regarding astrophysical sources of high-energy particles and radiation, i.e. supernova remnants, neutron stars, stellar-mass black holes, active galaxies, and clusters of galaxies among others. The operation of the future X-ray instruments will proceed in parallel with the operation of Fermi -LAT and the Cherenkov Telescope Array. We emphasize that the synergy between the X-ray and γ -ray observations is particularly important, and that the planned X-ray missions, when in conjunction with the modern γ -ray observatories, will indeed provide a qualitatively better insight into the high-energy Universe.
