cds-question@unistra.frsupernovaeSupernova remnants are among the most spectacular examples of astrophysical pistons in our cosmic neighborhood. The gas expelled by the supernova explosion is launched with velocities ~1000 kilometers per second into the ambient, tenuous interstellar medium, producing shocks that excite hydrogen lines. We have used an optical integral-field spectrograph to obtain high-resolution spatial-spectral maps that allow us to study in detail the shocks in the northwestern rim of supernova 1006. The two-component H{alpha} line is detected at 133 sky locations. Variations in the broad line widths and the broad-to-narrow line intensity ratios across tens of atomic mean free paths suggest the presence of suprathermal protons, the potential seed particles for generating high-energy cosmic rays.2013Sci...340...45Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Sci/340.45CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Sci/340.45https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Sci/340.45http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Sci/340.45https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Sci/340.45https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Sci/340.45http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Sci/340.45GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/other/Sci/340.45/tables1Properties of the shock front in the remnant of SN 1006 for 133 spatially binned locationsrecnoRecord number assigned by the VizieR team.
