| Abstract | The nature and location of the missing baryons in the universe remains a majormystery. We propose joint Chandra and MUSTANG-2/GBT observations of two closepairs of galaxy clusters recently detected in SZ by ACT with possibleintergalactic gas filaments between them. The MUSTANG-2 and ACT SZ data will becombined to model the SZ on both large and small scales. Both the Chandra X-rayimage 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 theclusters Abell 399 and 401. The combination of X-ray and SZ observations allowsthe density, temperature, pressure, and 3D shape of the filaments to bedetermined. These observations will help constrain the nature of the missing baryons in the universe. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
