Abstract | One of the first Swift-BAT AGN observed by {it NuSTAR} was the heavily-obscuredSy2 galaxy IC 751. Additional NuSTAR observations have shown that the objectsabsorption varies dramatically (~0.7-3.3e24 cm-2), such that IC 751 may be amore obscured version of the changing-look NGC 1365. IC 751s variablenature could portend the existence of a significant population of such objects.Notably, however, the IC 751 field has no useful 0.5-10 keV spectralconstraints, so we request a modest {it XMM- Newton} observation to characterizeIC 751, as well as two serendipitous NuSTAR-detected objects identified in thesame FOV. This 0.5-79 keV dataset will allow us to constrain the degree ofreflection and contamination present in IC 751, as well as secure NH constraints for the two serendipitous objects. |

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. |
