cds-question@unistra.frsupernova-remnantsh-ii-regionsradio-sourcesgalaxy-classification-systemsThe results of an extremely deep, 8-d long observation of the central kpc of the nearby starburst galaxy M82 using Multi-Element Radio Linked Interferometer Network (MERLIN) at 5GHz are presented. The 17{mu}Jy/beam rms noise level in the naturally weighted image makes it the most sensitive high-resolution radio image of M82 made to date. Over 50 discrete sources are detected, the majority of which are supernova remnants, but with 13 identified as H ii regions. Sizes, flux densities and radio brightnesses are given for all of the detected sources, which are all well resolved with a majority showing shell or partial shell structures. Those sources within the sample which are supernova remnants have diameters ranging from 0.3 to 6.7pc, with a mean size of 2.9pc.2008MNRAS.391.1384Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/391/1384CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/391/1384https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/391/1384http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/391/1384https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/391/1384https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/391/1384http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/391/1384GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/391/1384/table2 (Flux densities and deconvolved sizes of the sources detected in the 2002 5-GHz MERLIN data set)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/391/1384/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/391/1384/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/391/1384/table2?GETtext/xml+votable180.050000true148.942916769.67764440.0055555555555555566/7606https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/391/1384?format=asciiOpticalRadiodefaultJ/MNRAS/391/1384/table2Flux densities and deconvolved sizes of the sources detected in the 2002 5-GHz MERLIN data setrecnoRecord number assigned by the VizieR team.
