cds-question@unistra.frquasarsradio-sourcesstellar-distanceWe use the anticorrelation between the equivalent width (EW) of the CIV 1549{AA} emission line and the continuum luminosity in the quasars rest frame (Baldwin effect) to measure their luminosity distance as well as estimate cosmological parameters. We obtain a sample of 471 Type I quasars with the UV-optical spectra and EW (CIV) measurements in the redshift range of 2.3<z<7.1 including 25 objects at 5<z<7.1, which can be used to investigate the CIV Baldwin effect and determine cosmological luminosity distance. The relation EW(CIV)~({lambda}L{lambda}){gamma} can be applied to check the inverse correlation between the CIV EW and L{lambda} of quasars and give their distance, and the data suggest that the EW of CIV is inversely correlated with continuum monochromatic luminosities. On the other hand, we also consider dividing the Type I quasar sample into various redshift bins, which can be used to check if the CIV EW-luminosity relation depends on the redshift. Finally, we apply a combination of Type I quasars and Type Ia supernovae (SNIa) of the Pantheon sample to test the property of dark energy concerning whether or not its density deviates from the constant, and give the statistical results2023A&A...674A.163Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/674/A163CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/674/A163https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/674/A163http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/674/A163https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/674/A163https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/674/A163http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/674/A163GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/674/A163/table1 (The properties of the Type I quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/674/A163/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/674/A163/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/674/A163/table1?GETtext/xml+votable180.050000true26.596088132.20808720.0055555555555555566/8 680 763 2050 2094 2101 2121 2137 2168 2185 2204 2564 4100 4114 4118 4130 4149 4151 4192 4203 4216 4299 4344 4346-4347 4373 4378 4411 4439 4468 4499 4521 4542 4568 4578-4580 4591 4603 4606 4617 4621 4645-4646 4701 4708 4720 4751 4826-4827 4848 4861 4880 4892 4900 4906 4939 4946 4968 4970 4979 4992 5029 5033 5066 5083 5139 5143 5255 5277 5281 5290 5298 5307 5387 5404 5408 5453 5502 5537 5555 5586 5591 5595 5626 5681 5706 5757 5766 5780 5802 5847 5853 5882 5903 5922 5958 5979-5980 6000 6015 6024 6036 6041 6051 6094 6130 6169 6211 6213 6223 6234 6264 6266 6337 6384-6385 6401 6422-6423 6427 6436 6448 6476 6494 6546 6586 7183 7193 7235-7236 7241 7275 7374-7375 7379 7387 7416 7425 7447 7509 7560 7585 8213 8310 8346 8348 8350 8354 8358 8363 8405 8410 8428 8538 8544 8584 8623 8670 8683-8684 8725 8740 8755-8756 8871 8954 8987 9013 9021 9044 9092 9106-9107 9122 9164 9240 9248 9338 9340 9363 9394 9410 9433 9444 9459 9606 9615 9650 9659 9748 9777 9800 9811 9830 9836 9855 9863 9878 9883 9902 9907 9943 9945 9976 9984 10035 10115 10127 10138 10277 10317-10318 10387 10412 10486 10489 10512 10516 10555 10564 10578 10640 10643 10687 10727 10734 10747 10783 10819-10820 10912 10928 10939 10956 11003 11050 11075-11076 11106 11112 11121 11131 11180 11205 11241 11246 11248 11299 11312 11340 11367 11423 11443 11790 11839 11875 11930 12376 12660 13331 13423 17251 17266 17380 17382 17407 17496 17622 17642 17646 17703 17709 17723 17729 17740 17744 17753 17777 17789 17811 17891 17899 17906-17907 17969 17981-17982 17994 17997 18003 18019 18065 18078 18083 18088 18098 18175 18204 18215 18279 18301 18316 18319 18340 18344 18358 18387 18416 18422 18685-18686 18768 18772 18774 18798 18829 18837 18841 18850 19049 19057 19062 19087 19092-19093 19109 19120 19151 19159 19174 19189 19212 19345 19409 19434 19529 19564 19617 19634 19658 19682 19691 19759 19782 19822 19841 19875 19882 19884 19915 19921 19925 19952 20004 20014-20015 20047-20048 20167 20181 20229 20313 20320 20349 20424 21853 21991 22006 22355 25848 25979 25995 26015 26023 26096 26107 26109 26256 26293-26294 26356 26360 26381 26385 26414 26417 26454 26462 26494 26561 26596 26863 26867 26981 27091 27121 27124 27131 27224 27241 27284-27285 27289 27309 27314 27361 27414 27427 27439 27466 27494 27508 27549 27565 27601 27644 27659 27671 27683 27703 27732 27777 27804 27835 27868 27923 27962 27974 28021 28036 28042 28059 28124 28178 28210 28276 28327 28340 28347 28418 28454 28515 28593 28639 28660 31373 31390 31398 31411 31422 31449 31454 31473 31478 31665 31695 31699 32429 32438 32458 36773 36809 36839 450392.85864675833786e-19 3.5010283109654867e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/674/A163?format=asciiRadiodefaultJ/A+A/674/A163/table1The properties of the Type I quasarsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
