cds-question@unistra.frpulsarsgamma-ray-astronomyastronomical-models{gamma}-ray radiation from pulsars is usually thought to be mostly produced by the synchro-curvature (SC) losses of accelerated particles. Here, we present a systematic study of all currently reported, good-quality Fermi-LAT pulsar spectral data. We do so by applying a model which follows the particle dynamics and consistently computes the emission of SC radiation. By fitting observational data on a case by case basis, we are able to obtain constraints about the parallel electric field, the typical length-scale over which particles emit the bulk of the detected radiation, and the number of involved particles. The model copes well with data of several dozens of millisecond (MSPs) and young pulsars (YPs). By correlating the inferred model parameters with the observed timing properties, some trends are discovered. First, a non-negligible part of the radiation comes from the loss of perpendicular momentum soon after pair creation. Second, the electric field strongly correlates with both the inverse of the emission length-scale and the magnetic field at light cylinder, thus ruling out models with high-energy photon production close to the surface. These correlations unify young and millisecond pulsars under the same physical scenario, and predict that magnetars are intrinsically {gamma}-ray quiet via synchro-curvature processes, since magnetospheric particles are not accelerated enough to emit a detectable {gamma}-ray flux.2015MNRAS.453.2599Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/453/2599CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/492/923 : Pulsar Timing for Fermi Gamma-ray Space TelescopeJ/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012)J/MNRAS/424/2832 : Pulsars in {gamma}-ray sources (Lee+, 2012)J/ApJ/769/108 : Optical photometry of 4 millisecond pulsars (Breton+, 2013)J/ApJS/208/17 : 2nd Fermi LAT cat. of gamma-ray pulsars (2PC) (Abdo+, 2013)J/ApJ/814/128 : Timing noise + astrometry of Fermi-LAT pulsars (Kerr+, 2015)J/ApJS/218/23 : Fermi LAT third source catalog (3FGL) (Acero+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/453/2599https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/453/2599http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/453/2599https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/453/2599https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/453/2599http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/453/2599GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/453/2599/catalog (Timing parameters, timing-inferred properties, 0.1-100 GeV luminosity, and best-fitting parameters to the phase-averaged spectra for the 59 YPs (table 2) and the 22 MSPs (table 3) of our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/2599/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/2599/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/2599/catalog?GETtext/xml+votable180.050000true1.642573.18516670.0055555555555555566/1199 1684 2411 2855 3302 3681 3819 4750 12871 13106 13465 13750 14051 14270 14413 14424 14454 14608 14619 14621 14690 14692 14712 14840 15310 15376 15644 17955 18153 20552 21511 22154 22255 23646 23830 23952 24185 25065 28805 28814 28825 28894 28918 29261 29471 29505 29523 29575 30193 30244 30593 32160 33457 34034 37341 37343 37361 37848 37912 37923-37924 37937 38020 38022 38081 38361 39235 41598 41685 41743 41758 41857 41937 42173 42384 42438 44356 46237 47306 48193https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/453/2599?format=asciiGamma-rayRadiodefaultJ/MNRAS/453/2599/catalogTiming parameters, timing-inferred properties, 0.1-100 GeV luminosity, and best-fitting parameters to the phase-averaged spectra for the 59 YPs (table 2) and the 22 MSPs (table 3) of our sampleE_logx0[0.01/2.6]?
