We have discovered a new class of 11 transient radio sources characterized byrepeated, dispersed radio bursts. While periodicities detected from some ofthese objects suggest they are rotating neutron stars, they are not detected aspulsars through standard radio searches or through their time-averaged radioemission. We propose X-ray observations of two of these sources for which wehave a well-determined position and period. Analysis of a Chandra observationwith one of these sources serendipitously in the field already revealsanomalously bright X-ray emission. Further observations will enable tighterspectral constraints and help determine how these sources relate to otherneutron star populations such as X-ray isolated neutron stars, radio pulsars and magnetars.

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.
