PSR J1023+0038 is a binary system that hosts a neutron star and a low-mass,main-sequence companion star. It has been observed to switch on timescales ofyears between a radio millisecond pulsar and a disc-dominated state, ofuncertain origin. After its last switch to a disc-dominated state in 2013, thesource has been the object of extensive multi-wavelength monitoring campaigns,during which the continuous switch between three X-ray modes (high, low andflare) on timescales of 10 s has been observed. Here we propose the ultimate ,strictly simultaneous, multi-wavelength campaign to study in detail this uniquephenomenon. We will involve NuSTAR, XMM-EPIC, Swift-UVOT, XMM-OM, VLT/HAWK-I,VLA observations to probe models using correlations and lags, as well as to study the pulsed signal.

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.
