X-Ray Astronomy
• X-Rays – Light at high energies– Takes lots of energy to produce them
• Atmosphere absorbs X-Rays
• Most of the matter that we “see” is known to us from its X-Ray emission
X-Ray Astronomy
• Solar Studies in late 40’s
• Discovery of first extra solar source in 1962– Also discovery of faint glow (the “diffuse
background)
Galactic Center
•First high-resolution X-ray panorama of the Galactic center
•Detection of about 1,000 discrete X-ray sources
•Detection of large amounts of hot gas
The Deep Surveys
• 1Million seconds on Chandra Deep Field-South and 2 Million on CDF-N– Probe is 80 times deeper at low energies– 800 times deeper at hard energies– All data publicly available
• CDF-N detects about 500 discrete sources and 6 extended sources
Summary
• Operations are running smoothly
• Mission success – Design of the Observatory – Excellent and committed staff– Team effort involving all the players– Exciting and fundamental scientific results– Papers at a rate of ~10 per week
