Description We propose XMM-Newton EPIC observations of 4 AGN candidates hosted by dwarf
galaxies with a close dwarf galaxy companion to determine whether dwarf-dwarf
interactions can trigger the growth of an active massive black hole.
Intermediate mass black holes in today.s dwarf galaxies offer a unique window
into not only the typical masses of early black holes and the properties of the
galaxies that host them, but also how these seeds may have formed. Mergers among
massive galaxies are observed to fuel central AGN but whether or not this
process happens at lower masses in dwarf-dwarf interactions is unknown. Our
systematic study of dwarf pairs and the XMM-Newton X-ray observations proposed
here are uniquely suited for determining whether interacting dwarfs can harbor and fuel their own active massive black holes.

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.
