Title Catching A Giant X-ray Flare In An Extragalactic Compact Star Cluster

Author Prof Jimmy Irwin
Description We have discovered a new type of brief but very energetic flaring phenomenon in two X-ray sources associated with old, compact star clusters around nearby galaxies. These sources flare by factors of >100 to X-ray luminosities 1-2 orders of magnitude larger than the Eddington limit of a neutron star on time scales of <1 minute, yet the process does not destroy the object. These flares represent the most energetic sources ever discovered in globular clusters. We propose XMM-Newton observations of one of these sources that flares repeatedly to catch the flare with the pn to provide better timing and spectra during a flare to constrain the mass and emission mechanism of these intriguing objects.

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.
