Hot dust-obscured galaxies (Hot DOGs) are a very rare population of high-z hyperluminous (virgul10e14 Lsun) sources recently discovered in the WISE all-sky survey.Our exploratory AO12 observation provided the first X-ray spectrum of a Hot DOGand revealed a buried and intrinsically luminous QSO nucleus. We propose tocontinue this program aimed at probing the X-ray properties of these exceptionalAGN by observing three additional targets at zvirgul2.5. Given their spectacularluminosities and redshifts they may represent a rapid, dust-enshrouded phaseleading to the formation of the most massive elliptical galaxies. The proposedobservations are designed to get insight into the properties of the nuclearregion and the X-ray emitting source, responsible of their huge luminosity.

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.
