cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsredshiftedvisible-astronomyWe here propose a new model-independent technique to overcome the circularity problem affecting the use of gamma-ray bursts (GRBs) as distance indicators through the use of E_p_-E_iso_ correlation. We calibrate the E_p_-E_iso_ correlation and find the GRB distance moduli that can be used to constrain dark energy models. We use observational Hubble data to approximate the cosmic evolution through Bezier parametric curve obtained through the linear combination of Bernstein basis polynomials. In doing so, we build up a new data set consisting of 193 GRB distance moduli. We combine this sample with the supernova JLA data set to test the standard {Lambda}CDM model and its wCDM extension. We place observational constraints on the cosmological parameters through Markov Chain Monte Carlo numerical technique. Moreover, we compare the theoretical scenarios by performing the Akaike and Deviance Information statistical criteria.the 2{sigma} level, while for the wCDM model we obtain {Omega}_m_=0.34^+0.13^_-0.15_ and w=-0.86^+0.36^_-0.38_ at the 2{sigma} level. Our analysis suggests that {Lambda}CDM model is statistically favoured over the wCDM scenario. No evidence for extension of the {Lambda}CDM model is found.2019MNRAS.486L..46Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/486/L46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/486/L46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/486/L46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/486/L46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/486/L46https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/486/L46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/486/L46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/486/L46/tablea1 (List of the full GRBs used in this work and their redshift z and calibrated muGRB)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/486/L46/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/486/L46/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/486/L46/tablea1?GETtext/xml+votable180.050000true75.444583311.78136110.0055555555555555566/207 314 393 500 557 646 962 2044 3059 3089 3111 3536 3586 3935 4449-4450 5051 5073 5625 5840 6141 6258 6261 6521 6523 7182 7227 7518 7532 7589 7650 7750 8074 8103 8569 8798 9370 9437 9643 9662 9897 9910 9989 9998 10080 10424 10447 10519 10589 11058 11220 11308 11657 11822 12006 12230 12438 13312 13694 13720 13779 13924 14259 15233 15295 15340 15530 16057 16282 16661 16919 16991 17038 17316 17411 17703 17733 17749 17758 17814 17911 17982 18030 18728 19097 19164 19519 19731 19864 20053 20191 20372 20460 21284 21595 21962 22008 23413 24072 24779 24993 25146 25148 25192 25452 26365 26441 26503 27287 27320 27541 27810 27933 27961-27962 28032 28058 28063 28344 28546 28555 28930 29231 29731 30557 31185 31281 31385 31494 31521 32239 32646 32713 33004 33050 33146 33278 33525 33735 33813 33832 33860 34147 34440 34788 34832 35227 35285 35569 35633 35844 36074 36460 37123 37391 37459 37505 38926 39076 39427 39594 39993 40433 40778 40784 41095 42545 43853 44212 44857 45347 45401 45510 45828 45835 45938 46022 46212 46218 46488 46510 46594 46899 46989 47148 47162 47245 48054 48447 48458 48804 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/486/L46?format=asciiGamma-rayOpticaldefaultJ/MNRAS/486/L46/tablea1List of the full GRBs used in this work and their redshift z and calibrated muGRBSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
