Abstract

ABSTRACT The x-ray band of the spectrum is the natural place to perform super-high resolution imaging of astronomical objects. Because x-ray sources can have very intense surface brightness and interferometers can be made with very short baselines, x-ray interferometry has great potential. We will discuss MAXIM, the Micro-Arcsecond X-ray Imaging Mission and MAXIM Pathfinder, a coordinated pair of x-ray astronomy missions designed to exploit the potential of x-ray interferometry. We will show how it is possible to achieve huge gains in resolution using today's technology. The Pathfinder mission will achieve resolution of 100 micro-arcseconds and will image the coronae of the nearby stars. MAXIM, with a design specification of 0.1 micro-arcseconds, has the goal of imaging the event horizons of massive black holes. We will explain the architecture of the missions and describe the activities NASA is supporting in the area of x-ray interferometry. Keywords: X-rays, Interferometry, X-ray Astronomy, X-ray Optics, Grazing Incidence Optics
