Jansky Very Large Array (VLA). Spanning 1 to 85.5GHz and 7 epochs from 1.5 to 82.3d, our observations of GRB140311A are the most detailed joint radio and millimeter observations of a GRB afterglow at z>~5 to date. In conjunction with optical/near-IR and X-ray data, the observations can be understood in the framework of radiation from a single blast wave shock with energy E_K,iso_~8.5x10^53^erg expanding into a constant density environment with density, n_0_~8cm^-3^. The X-ray and radio observations require a jet break at t_jet_~0.6d, yielding an opening angle of {theta}_jet_~4{deg} and a beaming-corrected blast wave kinetic energy of E_K_~2.2x10^50^erg. The results from our radio follow-up and multiwavelength modeling lend credence to the hypothesis that detected high-redshift GRBs may be more tightly beamed than events at lower redshift. We do not find compelling evidence for reverse shock emission, which may be related to fast cooling driven by the moderately high circumburst density.2018ApJ...858...65Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/858/65CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/833/88 : GRB 160509A VLA monitoring campain results (Laskar+, 2016)J/ApJ/829/7 : The third Swift/BAT GRB catalog (BAT3) (Lien+, 2016)J/ApJ/814/1 : GRB 120326A, 100418A + 100901A multi-wavelength obs.J/ApJ/781/37 : Multi-band photometry of GRB 130427A (Perley+, 2014)J/A+A/557/A12 : Optical light curves of {gamma}-ray bursts (Zaninoni+, 2013)J/MNRAS/428/729 : GRB Swift X-ray light curves analysis (Margutti+, 2013)J/ApJ/746/156 : Radio afterglow observations of GRBs (Chandra+, 2012)J/MNRAS/397/1177 : Swift-XRT observations of GRBs (Evans+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/858/65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/858/65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/858/65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/858/65https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/858/65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/858/65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapGamma-rayOpticalMillimeterRadiodefaultJ/ApJ/858/65/table2Swift UVOT observations of GRB 140311ArecnoRecord number assigned by the VizieR team.
