cds-question@unistra.frradio-sourcesredshiftedLate-time astrophysical probes offer a powerful way to investigate the expansion history of the Universe. Among these probes, fast radio bursts (FRBs) are millisecond-duration astrophysical transients whose extragalactic origin makes them a promising addition to studies of large-scale structure. Their dispersion measures encode information about the intervening cosmic plasma, which can be linked to cosmological distances. We used late-time probes, such as well-localized FRBs, baryon acoustic oscillations (BAO), supernovae (SNe), and cosmic chronometers (CC) to constrain cosmological parameters through a model-independent cosmographic approach. We integrated FRB data with BAOs from Dark Energy Spectroscopic Instrument (DESI) DR2, SNe, and CCs to derive constraints on the Hubble constant (H0), the deceleration parameter (q0), and the jerk parameter (j0), using Markov Chain Monte Carlo (MCMC) analysis for parameter estimation. The cosmographic approach with FRBs alone provides H0=66.35^+4.13^_-5.04_km/s/Mpc, q0=-0.33_-0.15_^+0.21^, and j0=0.83_-0.67_^0.57^, corresponding to a precision of ~6% for the Hubble constant and showing consistency with the {LAMBDA}CDM expectation. The DESI+CMB dataset yields H0=65.59^+1.25^_-1.24_km/s/Mpc, q0=-0.29_-0.08_^+0.07^, and j0=0.58_-0.04_^+0.03^, providing a ~2% precision on H0 and may suggest a possible tension in the late-time kinematic sector relative to the {LAMBDA}CDM expectation when BAO measurements are calibrated with a Planck-inferred sound horizon. Combining the FRB, SNe, DESI+CMB, and CC datasets further tightens the constraints to H0=68.03^+0.53^_-0.52_km/s/Mpc, q0=-0.41+/-0.02, and j0=0.55+/-0.02, with the jerk parameter remaining lower than j0=1 at the 1{sigma} confidence level. These findings hint at a possible late-time kinematic tension, as indicated by the inferred value of the jerk parameter, which is primarily driven by the DESI+CMB dataset under standard early-Universe assumptions for the sound horizon. At the current level of observational precision, FRBs play a complementary role in the cosmographic analysis, with their impact expected to increase as larger and more precise samples of well-localized events become available.2026A&A...712A.236Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A236CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/675/A99 : FRBs search with Fermi-LAT (Principe+, 2023)J/A+A/698/A18 : Selected CHIME FRB sample (Zhang+, 2025)J/ApJS/257/59 : First CHIME/FRB Fast Radio Burst CatalogJ/MNRAS/500/655 : Galactic DM contribution to the extragalactic FRBsJ/MNRAS/511/1961 : New CHIME/FRB I catalogue updates releasedhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/712/A236https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/712/A236http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/712/A236https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/712/A236https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/712/A236http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/712/A236GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/712/A236/tablea1 (Fast Radio Burst dataset)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/712/A236/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/712/A236/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/712/A236/tablea1?GETtext/xml+votable180.050000true149.4862568.82555560.0055555555555555566/504 1547 2260 2648 3527 3532 3555 3563 3683 3801 4372 5653 7025 7086 7551 7604 7629 7636 7642 7654 7662 7961 7964 7972 7978 7984 8313 8886 9388 9444 9557 9813 10729 10845 10983 11647 11709 11736 11746 11989 12051-12052 12064 12067 13518 13613 14101 14144 15355 15819-15820 15822 15827 15833 15851 16057 16096 16112 16144 16155 16165 16167 16365 16522 16648 18448 18590 19176 19806 19912 20312 22451 22969 22996 23544 23574 24301 24507 24924 25416 25618 27395 27406 27437 28470 30104 30859 32415 32682 33331 34347 34930 35397 36109 36332 39271 42193 42250 43874 45152 45155 45160 45914 45917 45987 46559 46784 46939 48473 48810https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/712/A236?format=asciiRadiodefaultJ/A+A/712/A236/tablea1Fast Radio Burst datasetrecnoRecord number assigned by the VizieR team.
