cds-question@unistra.frradio-continuum-emissioninterferometrypulsarsWe present a wide-field, subarcminute-resolution VLA image of the Galactic center region at 330MHz. With a resolution of ~7"x12" and an rms noise of 1.6mJy/beam, this image represents a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity has more than tripled the census of small-diameter sources in the region, has resulted in the detection of two new nonthermal filaments (NTFs), 18 NTF candidates, and 30 pulsar candidates, reveals previously known extended sources in greater detail, and has resulted in the first detection of Sagittarius A* in this frequency range.2004AJ....128.1646Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/1646CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/74/181 : Small-diameter radiosources catalogue (Zoonematkermani+, 1990)J/ApJS/91/347 : A 5-GHz VLA Survey of the Galactic Plane (Becker+ 1994)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/A+A/368/835 : Soft X-ray sources in the Galactic Center regionJ/A+A/433/117 : L- + M-band imaging of the Galactic Center (Viehmann+, 2005)J/A+AS/52/63 : H I Survey of the Galactic Center Region (Burton+ 1983)J/ApJ/589/225 : Chandra X-ray sources toward Galactic CenterJ/ApJS/118/201 : Galactic Center 6 and 20cm survey (Lazio+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/1646https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/1646http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/1646https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/1646https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/1646http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/1646GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/1646/table2 (Galactic Center P-band Survey of Small-Diameter Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/1646/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/1646/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/1646/table2?GETtext/xml+votable180.050000true265.8509167-31.22766670.005555555555555556Cone search capability for table J/AJ/128/1646/table5 (Pulsar nondetections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/1646/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/1646/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/1646/table5?GETtext/xml+votable180.050000true264.717667-29.9308330.0055555555555555565/7205 7206 7207 7212 7213 6/28813 28815 28818 28819 28872 28874 28896https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/1646?format=asciiRadiodefaultJ/AJ/128/1646/table2Galactic Center P-band Survey of Small-Diameter SourcesrecnoRecord number assigned by the VizieR team.
