RevisedV/Vmax test with incompleteness-compensated factors and its application to X-ray quasar sample

Abstract Both density- and luminosity-evolution of quasars proceed sumultaneously. If only one of them is considered, the value of 〈V/Vmax〉 would be too high. Here we present an idea that the quasar luminosity-redshift relationship curve can be obtained by statistics, from which the incompleteness-c...

Here we present an idea that the quasar luminosity-redshift relationship curve can be obtained by statistics, from which the incompleteness-compensated factorK(Z\|lmin) for each source will be given, and then theV/Vmax test for density law can be carried out. We use this revisedV/Vmax test in investigating 3CR and 4C samples including the 3CR sources detected in X-ray. The result is that the space density distribution of quasars is relative toqo.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Density Distribution</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Space Density</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Relationship Curve</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Quasar Sample</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Space Density Distribution</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zu-Wei, Liu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Astrophysics and space science</subfield><subfield code="d">Kluwer Academic Publishers, 1968</subfield><subfield code="g">109(1985), 2 vom: Feb., Seite 333-344</subfield><subfield code="w">(DE-627)129062723</subfield><subfield code="w">(DE-600)629-4</subfield><subfield code="w">(DE-576)014393522</subfield><subfield code="x">0004-640X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:109</subfield><subfield code="g">year:1985</subfield><subfield code="g">number:2</subfield><subfield code="g">month:02</subfield><subfield code="g">pages:333-344</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">https://doi.org/10.1007/BF00651279</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHY</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-AST</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-AST</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_11</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_22</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_24</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_31</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_40</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_47</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2002</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2279</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2286</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4012</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4046</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4082</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4103</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4305</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4306</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4700</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">109</subfield><subfield code="j">1985</subfield><subfield code="e">2</subfield><subfield code="c">02</subfield><subfield code="h">333-344</subfield></datafield></record></collection>

abstract	Abstract Both density- and luminosity-evolution of quasars proceed sumultaneously. If only one of them is considered, the value of 〈V/Vmax〉 would be too high. Here we present an idea that the quasar luminosity-redshift relationship curve can be obtained by statistics, from which the incompleteness-compensated factorK(Z\|lmin) for each source will be given, and then theV/Vmax test for density law can be carried out. We use this revisedV/Vmax test in investigating 3CR and 4C samples including the 3CR sources detected in X-ray. The result is that the space density distribution of quasars is relative toqo. © D. Reidel Publishing Company 1985
