cds-question@unistra.frradio-sourcesredshiftedBased on the first CHIME/FRB catalog, three volume-limited samples of fast radio bursts (FRBs) are built, with Sample 1, 2 and 3 corresponding to a fluence cut of 5, 3 and 1, respectively. The Lynden-Bell's c^-^ method is applied to study their energy function and event rate evolution with redshift (z). Using the non-parametric Kendell's {tau} statistics, it is found that the FRB energy (E) strongly evolves with redshift as E(z){prop.to}(1+z)^1.24^ for Sample 1, E(z){prop.to}(1+z)^0.98^ for Sample 2 and E(z){prop.to}(1+z)^1.99^ for Sample 3. After removing the redshift dependence, the local energy distributions of the three samples can be well described by a broken power-law form with a broken energy of ~10^40^ erg. Meanwhile, the redshift distributions of Samples 1 and 2 are identical but different from that of Sample 3. Interestingly, we find that the event rates of Samples 1 and 2 of are independent of redshift, and Sample 3 decreases as a single power-law form with an index of -2.41. The local event rates of the three samples of CHIME FRBs are found to be consistently close to ~10^4^Gpc^-3^yr^-1^, which is comparable with some previous estimates. In addition, we notice the event rate of Sample 3 FRBs with lower energies not only exceeds the star formation rate at the lower redshifts but also always declines with the increase of redshift. We suggest that the excess of FRB rates as compared with the star formation rate at low redshift is mainly resulted from the low energy FRBs that could originate from the older stellar populations.2025A&A...698A..18Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/698/A18CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/253/10 : 12yrs of R-band photometry of quasar 3C 454.3 (Fan+, 2021)J/ApJS/257/59 : First CHIME/FRB Fast Radio Burst CatalogJ/MNRAS/509/1227 : Hidden repeating fast radio bursts (Chen+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/698/A18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/698/A18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/698/A18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/698/A18https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/698/A18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/698/A18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/698/A18/table1 (The selected CHIME FRB sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/698/A18/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/698/A18/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/698/A18/table1?GETtext/xml+votable180.050000true286.5881.220.0055555555555555566/455 494 692 719 771 787 971 982 1199 1238 1267 1277 1454 1832 1858 2034 2056 2065 2085 2088 2099 2123 2182 2356 2773 2876 2914 2916 2971 3029 3084 3147 3178 3199 3318 3328 3350 3386 3401 3444 3528 3623 3648 3678 3785 3816 3855 3892 3902 3929 3933-3934 3952 3961 3964 4017 4039 4051 4053 4057 4071 4085-4087 4092 4095 4097 4179 4246 4394 4546 4789 4800 4817 5266 5363 5398 5503 5525 5553 5608 5611 5639 5643 5646 5678 5798 5801 5883 5899 5975 6102 6121 6134 6142 6351 6404 6565 6770 6773 6833 6983 7008 7021-7022 7051 7112 7215 7243 7283 7343 7390 7490 7495 7632 7661 7682 7698 7713 7717 7750 7773 7815 7821 7843 7868 7872 7923 7929 7950 7975 7981 7983 8015 8019 8035 8063 8072 8111 8123 8142 8145 8152-8154 8184 8186 8553 8805 8957 9016 9024 9082 9093 9121 9259 9337 9457 9533 9544 9619 9632 9693 9725 9731 9813 9824 9872 9956 10004 10015 10073 10085 10115 10170 10194 10220 10230 10259 10353 10551 10708 10729 10834 10952 11063 11166 11177 11186-11187 11202 11231 11244 11405 11494 11536 11566 11570 11616 11629 11647 11668 11681 11727 11748 11766 11770 11831 11838 11851 11914 11940 11967 11977 11995 12104 12132 12134 12146 12148 12157 12195 12210-12211 12220 12271 12275 12286-12287 12620 12978 13135 13158 13222 13354 13369 13617 13688 13690 13770 13931 13943 14114 14220 14427 14476 14765 14975 15288 15329 15466 15518 15524 15539 15814 15843 15873 15899 15905 15912 15969 15989 16081 16115 16137 16159 16169 16174 16215 16235 16244 16287 16298 16310 16330-16331 16340 16347 16363 16366 16373 16375 16383 17611 17881 17898 18167 18410 19153 19227 19469 19522 19547 19581 19635 19862 19869 19876 19890 19960 20021 20102 20457 22084 22297 22321 22447 22757 23030 23036 23411 23470 23788 23974 24019 24095 24112 24123 24255 24285 24316 24379 24507 25887 26233 26391 26605 26619 27131 27485 27856 28150 28189 28273 28278 28326 28370 28433 28552 28555 28576 28647 28663 30079 31359 31603 31626 31870 31979 31995 32062 32235 32280 32439 32541 40940https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/698/A18?format=asciiRadiodefaultJ/A+A/698/A18/table1The selected CHIME FRB sampleFluenceFluenceJy.msphot.fluence;em.gamma.hardfloate_FluenceFluence errorJy.msstat.error;phot.fluencefloatv2Second central frequency for observationstat.fit.paramfloatv1First central frequency for observationstat.fit.paramfloatEnergyEnergy estimate1e-07Wphys.energydoublee_EnergyEnergy estimate error1e-07Wstat.error;phys.energydoubleFlag[0/1] Quality flagmeta.code.errorintRepeat[YES NO] Repeatmeta.codecharSimbadSimbad column added by the CDSmeta.ref.urlchar_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
