Title MRK 1239: THE NATURE OF THE DISTANT X-RAY EMISSION IN A SEYFERT 1
DOI https://doi.org/10.57780/esa-fnd1glj
Abstract In the highly polarised NLS1 Mrk1239, the primary X-ray emission from the innerblack hole region appears to be completely absorbed revealing the underlyinghost galaxy emission. This low energy emission-line spectrum was fitted with acombination of a collisionally ionised plasma and cold, optically thickreflected emission from the distant torus. With the highest sensitivity NuSTARspectra, we will peer through the absorbing column to accurately determine thecontinuum model, the level of absorption, and the distant torus parameters. Constraining the torus parameters will allow us to utilize simultaneous XMM RGSdata to determine the origin of the photoionised emission at low energies.

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.
