TL;DR
The Advanced X-ray Imaging Satellite (AXIS) is a next-generation mission that significantly improves upon Chandra's capabilities, enabling groundbreaking studies of cosmic phenomena with higher resolution, sensitivity, and faster response times.
Contribution
AXIS introduces advanced lightweight silicon optics and improved detectors, offering a major leap in X-ray imaging resolution, sensitivity, and rapid response for astrophysical research.
Findings
AXIS's PSF is nearly twice as sharp on-axis as Chandra's.
Field of view for subarcsecond imaging is 70 times larger.
Sensitivity for extended sources is 50 times greater than Chandra.
Abstract
Much of the baryonic matter in the Universe, including the most active and luminous sources, are best studied in the X-ray band. Key advances in X-ray optics and detectors have paved the way for the Advanced X-ray Imaging Satellite (AXIS), a Probe-class mission that is a major improvement over Chandra, which has generated a steady stream of important discoveries for the past 2 decades. AXIS can be launched in the late 2020s and will transform our understanding in several major areas of astrophysics, including the growth and fueling of supermassive black holes, galaxy formation and evolution, the microphysics of cosmic plasmas, the time-variable universe, and a wide variety of cutting-edge studies. Relative to Chandra, the AXIS PSF is nearly twice as sharp on-axis; its field of view for subarcsecond imaging 70 times larger by area; its effective area at 1 keV is 10 times larger. The…
