The Chandra X-Ray Observatory: progress report and highlights

摘要

Over the past 13 years, the Chandra X-ray Observatory’s ability to provide high resolution X-ray images and spectrahave established it as one of the most versatile and powerful tools for astrophysical research in the 21supst/sup century. Chandra explores the hot, x-ray-emitting regions of the universe, observing sources with fluxes spanning more than 10 orders of magnitude, from the X-ray brightest, Sco X-1, to the faintest sources in the Chandra Deep Field South survey. Thanks to its continuing operational life, the Chandra mission now also provides a long observing baseline which, in and of itself, is opening new research opportunities. In addition, observations in the past few years have deepened our understanding of the co-evolution of supermassive black holes and galaxies, the details of black hole accretion, the nature of dark energy and dark matter, the details of supernovae and their progenitors, the interiors of neutron stars, the evolution of massive stars, and the high-energy environment of protoplanetary nebulae and even the interaction of an exo-planet with its star. Here we update the technical status, highlight some of the scientific results, and very briefly discuss future prospects. We fully expect that the Observatory will continue to provide outstanding scientific results for many years to come.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
