cds-question@unistra.frradio-sourcesWe present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800MHz from 2018 July 25 to 2019 July 1, including 62 bursts from 18 previously reported repeating sources. The catalog represents the first large sample, including bursts from repeaters and nonrepeaters, observed in a single survey with uniform selection effects. This facilitates comparative and absolute studies of the FRB population. We show that repeaters and apparent nonrepeaters have sky locations and dispersion measures (DMs) that are consistent with being drawn from the same distribution. However, bursts from repeating sources differ from apparent nonrepeaters in intrinsic temporal width and spectral bandwidth. Through injection of simulated events into our detection pipeline, we perform an absolute calibration of selection effects to account for systematic biases. We find evidence for a population of FRBs-composing a large fraction of the overall population-with a scattering time at 600MHz in excess of 10ms, of which only a small fraction are observed by CHIME/FRB. We infer a power-law index for the cumulative fluence distribution of {alpha}=-1.40+/-0.11(stat.)_-0.09_^+0.06^(sys.), consistent with the -3/2 expectation for a nonevolving population in Euclidean space. We find that {alpha} is steeper for high-DM events and shallower for low-DM events, which is what would be expected when DM is correlated with distance. We infer a sky rate of [820+/-60(stat.)_-200_^+220^(sys.)]/sky/day above a fluence of 5Jy.ms at 600MHz, with a scattering time at 600MHz under 10ms and DM above 100pc/cm^3^.2021ApJS..257...59Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/257/59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/PASA/33.45 : FRBCAT: The Fast Radio Burst (FRB) Cat.
