|Title||The temporal evolution of the puzzling central source in RCW103|
|Author||Dr Andrea De Luca|
|Description||1E 161348-5055 is a point-like, radio-quiet X-ray source at the center of the 2000-years-old supernova remnant RCW103. Recent observations unveiled a unique phenomenology: (i) the source has a dramatic (factor 100) long-term flux variability with outbursts possibly recurrent on the few year time scale; (ii) its emission is strongly modulated with a puzzling 6.67 hour periodicity; (iii) no counterpart in the optical-infrared has been found yet. In view of the source variability, XRT onboard Swift is currently performing a monthly monitoring campaign. Here we ask for a new 75 ks XMM triggered observation to be performed if a new outburst will be detected. Studying the 6.67 hours periodicity in the high state regime will shed light on the nature of this puzzling source.|

|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.
