Description | PSR J1741-2054 was discovered as a gamma-ray pulsar in a blind search of Fermi sources. We detected radio pulses and found a very low dispersion measure, implying it is very nearby, and thus one of the closest middle-aged pulsars. Our Chandra observations imaged the pulsar, a pulsar-wind nebula (PWN), and a long trail. Detection of an Halpha bow shock gave a space velocity of 150 km/s. We propose a 70 ksec XMM observation to detect the X-ray pulsations, and accurately measure the spectra of the pulsar and PWN/trail. Time-resolved spectra will constrain the X-ray emission mechanism. We will determine the thermal and non-thermal spectra of the pulsar. The former will help to constrain the NS equation of state. |

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. |
