cds-question@unistra.frpulsarsgamma-ray-astronomyWe present a detailed view of the pulsar wind nebula (PWN) HESS J1825--137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting for its anomalously large size and spectral characteristics. The nebula is studied using a deep exposure from over 12 years of H.E.S.S. I operation, together with data from H.E.S.S. II improving the low energy sensitivity. Enhanced energy- dependent morphological and spatially-resolved spectral analyses probe the Very High Energy (VHE, E>0.1TeV) gamma-ray properties of the nebula. The nebula emission is revealed to extend out to 1.5 degrees from the pulsar, ~1.5 times further than previously seen, making HESS J1825-137, with an intrinsic diameter of ~100pc, potentially the largest gamma-ray PWN currently known. Characterisation of the nebula's strongly energy-dependent morphology enables the particle transport mechanisms to be constrained. A dependence of the nebula extent with energy of R{prop.to} E^alpha^ with alpha=-0.29+/-0.04(stat)+/-0.05(sys) disfavours a pure diffusion scenario for particle transport within the nebula. The total gamma-ray flux of the nebula above 1~TeV is found to be (1.12+/-0.03(stat)+/-0.25(sys))x10^-11^cm^-2^s^-1^, corresponding to ~64% of the flux of the Crab Nebula. HESS J1825-137 is a PWN with clear energy-dependent morphology at VHE gamma-ray energies. This source is used as a laboratory to investigate particle transport within middle-aged PWNe. Deep observations of this highly spatially-extended PWN enable a spectral map of the region to be produced, providing insights into the spectral variation within the nebula.2019A&A...621A.116Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/621/A116CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/621/A116https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/621/A116http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/621/A116https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/621/A116https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/621/A116http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/621/A116GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/621/A116/boxfits (Spectral fit information for all boxes (analysis A, tab. 5 in paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/621/A116/boxfits?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/621/A116/boxfits?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/621/A116/boxfits?GETtext/xml+votable180.050000true276.03441-14.100040.005555555555555556Cone search capability for table J/A+A/621/A116/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/621/A116/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/621/A116/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/621/A116/list?GETtext/xml+votable180.050000true276.42082-13.839170.0055555555555555566/29119 29162-29163 29461 29504-29505https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/621/A116?format=asciiRadioGamma-raydefaultJ/A+A/621/A116/anaafullSpectral points from 0.8deg radius region (analysis A, fig. 2 in paper)recnoRecord number assigned by the VizieR team.
