| Abstract | Of the hundreds of rotation-powered pulsars with detected PWNe, threestand out by their extremely under-luminous nebulae relative to theirspin-down power. PSR J1617-5055, PSR J2022+3842, and PSR J1838-0655 displayremarkably similar properties, (1) a PWN to PSR flux ratio of <0.1 in the2-10 keV band, (2) anomalously flat (Gamma < 1) Chandra spectra, (3) highlymodulated pulsations (60-100%), and (4) lack of a Fermi pulsed signal. Wepropose a NuSTAR and XMM broadband X-ray observation of PSR J1838-0655, thebrightest in the NuSTAR band. By studying this rare class of pulsars wehope to address their exceptionalism, key to more fully understanding theemission mechanism of pulsars. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
