Description | Of the hundreds of rotation-powered pulsars with detected PWNe, three stand out by their extremely under-luminous nebulae relative to their spin-down power. PSR J1617-5055, PSR J2022+3842, and PSR J1838-0655 display remarkably similar properties, (1) a PWN to PSR flux ratio of <0.1 in the 2-10 keV band, (2) anomalously flat (Gamma < 1) Chandra spectra, (3) highly modulated pulsations (60-100%), and (4) lack of a Fermi pulsed signal. We propose a NuSTAR and XMM broadband X-ray observation of PSR J1838-0655, the brightest in the NuSTAR band. By studying this rare class of pulsars we hope to address their exceptionalism, key to more fully understanding the emission mechanism of pulsars. |

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. |
