(DOE/Lawrence Berkeley National Laboratory) An international team led by a cosmologist at Lawrence Berkeley National Laboratory has extended the relationship between the x-ray luminosity and the mass of galaxy clusters as measured by gravitational lensing, improving the reliability of mass measurements of much older, more distant, and smaller galactic structures.

These refined measurements will benefit both the understanding of dark matter and the nature of dark energy as well.
