Description | We propose to observe a flux- and volume-limited complete sample of GPS radio galaxies. The goal of the proposals is to determine: a. the presence of hot confining gas around the active nucleus, and its properties, through its optically thin soft X-ray emission; b. the presence of cold environment gas through the measurement of X-ray absorption - in the most extreme case, Compton-thick. These measurements will provide tests for the current scenarios to explain the origin of these objects. We request 4 targets to be observed within the XMM-Newton AO2, for a total allocation time of 80 ks. This list includes 1404+286, the first GPS radio galaxy where a poor quality ASCA observation suggests the above components may have been simultaneously detected. |

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. |
