| Description | The nature and location of the missing baryons in the universe remains a major mystery. We propose joint Chandra and MUSTANG-2/GBT observations of two close pairs of galaxy clusters recently detected in SZ by ACT with possible intergalactic gas filaments between them. The MUSTANG-2 and ACT SZ data will be combined to model the SZ on both large and small scales. Both the Chandra X-ray image and SZ allow the separation of the cluster and the filament gas. Recently, X-ray and SZ observations have been used to study the filament between the clusters Abell 399 and 401. The combination of X-ray and SZ observations allows the density, temperature, pressure, and 3D shape of the filaments to be determined. These observations will help constrain the nature of the missing baryons in the universe. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
