cds-question@unistra.frpulsarsradio-sourcessurveysinterferometryWe present the detection of 661 known pulsars observed with the Australian SKA Pathfinder (ASKAP) telescope at 888MHz as part of the Rapid ASKAP Continuum Survey (RACS). Detections were made through astrometric coincidence and we estimate the false alarm rate of our sample to be ~0.5%. Using archival data at 400 and 1400MHz, we estimate the power-law spectral indices for the pulsars in our sample and find that the mean spectral index is -1.78+/-0.6. However, we also find that a single power law is inadequate for modeling all the observed spectra. With the addition of flux densities between 150MHz and 3GHz from various imaging surveys, we find that up to 40% of our sample show deviations from a simple power-law model. Using Stokes V measurements from the RACS data, we measured the circular polarization fraction for 9% of our sample and find that the mean polarization fraction is ~10% (consistent between detections and upper limits). Using the dispersion-measure-derived distance, we estimate the pseudo-luminosity of the pulsars and do not find any strong evidence for a correlation with the pulsars' intrinsic properties.2023ApJ...956...28Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/956/28CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/psr : ATNF Pulsar Catalogue (Manchester+, 2005)J/MNRAS/273/411 : Multifrequency fluxes of 280 pulsars (Lorimer+ 1995)J/MNRAS/301/235 : Multifrequency polarimetry of 300 pulsars (Gould+, 1998)J/A+AS/136/571 : Pulsars identified from the NRAO VLA Sky Survey (Han+ 1999)J/A+AS/147/195 : Pulsar spectra of radio emission (Maron+, 2000)J/MNRAS/372/777 : Parkes Multibeam Pulsar Survey.
