Images & Data
The unprecedented spatial resolution and sensitivity of the Chandra X-ray Observatory provides a rich archive of serendipitous sources. The Chandra Multiwavelength Project (ChaMP) seeks to understand the nature and evolution of quasars, galaxies, and clusters of galaxies in a large, carefully constructed multi-wavelength survey. A team of scientists, led by staff members at the Chandra X-ray Center (CXC) with collaborators from NOAO, MIT, MMTO, SDSS, UofA, MSU, OSU, Ohio, UT, Rome, Italy and Bristol, UK, is carrying out a multi-wavelength identification program for these X-ray sources.

In addition to our extragalactic study, a Chandra Galactic Plane survey, ChaMPlane, is being led by Josh Grindlay

The ChaMP has effectively retired, and is resting on her laurels.
