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.
