cds-question@unistra.frradio-galaxiesradio-continuum-emissionWe present the first part of the observations made for the Continuum Halos in Nearby Galaxies, an EVLA Survey (CHANG-ES) project. The aim of the CHANG-ES project is to study and characterize the nature of radio halos, their prevalence as well as their magnetic fields, and the cosmic rays illuminating these fields. This paper reports observations with the compact D configuration of the Karl G. Jansky Very Large Array (VLA) for the sample of 35 nearby edge-on galaxies of CHANG-ES. With the new wide bandwidth capabilities of the VLA, an unprecedented sensitivity was achieved for all polarization products. The beam resolution is an average of 9.6" and 36" with noise levels reaching approximately 6 and 30{mu}Jy/beam for C- and L-bands, respectively (robust weighting). We present intensity maps in these two frequency bands (C and L), with different weightings, as well as spectral index maps, polarization maps, and new measurements of star formation rates (SFRs). The data products described herein are available to the public in the CHANG-ES data release available at http://www.queensu.ca/changes. We also present evidence of a trend among galaxies with larger halos having higher SFR surface density, and we show, for the first time, a radio continuum image of the median galaxy, taking advantage of the collective signal-to-noise ratio of 30 of our galaxies. This image shows clearly that a "typical" spiral galaxy is surrounded by a halo of magnetic fields and cosmic rays.2015AJ....150...81Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.queensu.ca/changes : CHANG-EShttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/81https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/81/galaxies (Star formation rates , and flux densities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/81/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/81/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/81/galaxies?GETtext/xml+votable180.050000true25.7613.64505560.005555555555555556Cone search capability for table J/AJ/150/81/table1 (Observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/81/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/81/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/81/table1?GETtext/xml+votable180.050000true25.7613.64505560.0055555555555555566/2409 5067 5469 5504 5587 5639 5995 6037 7424 7550 7584 8225 10674 10761 10888 10979 10986 11000 11375 18387 25083 26175 26223 27246 27767 27861 27862 28141 28184 31321 40410 40514 44026 450541.0436059889190735e-24 9.029279001593864e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/81?format=asciiRadiodefaultJ/AJ/150/81/imagingImaging results for the C band , and for the L bandrecnoRecord number assigned by the VizieR team.
