Since structures form hierarchically, the presence of collapsed objects at high-redshifts can set strong lower limits on mx. We place robust constraints on mx using recent results from the {\\it Swift} database of high-redshift gamma-ray bursts (GRBs). We parameterize the redshift evolution of the ratio between the cosmic GRB rate and star formation rate (SFR) as ∝(1+z)α, thereby allowing astrophysical uncertainties to partially mimic the cosmological suppression of structures in WDM models. Using a maximum likelihood estimator on two different z>4 GRB subsamples (including two bursts at z>8), we constrain mx≳1.6-1.8 keV at 95% C.L., when marginalized over a flat prior in α. We further estimate that 5 years of a SVOM-like mission would tighten these constraints to mx≳2.3 keV. Our results show that GRBs are a powerful probe of high-redshift structures, providing robust and competitive constraints on mx."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","quality_controlled":"1","oa":1,"date_created":"2024-09-06T07:25:13Z","publication":"Monthly Notices of the Royal Astronomical Society","publisher":"Oxford University Press","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stt674","open_access":"1"}],"article_processing_charge":"No","extern":"1","_id":"17646","page":"3218-3227","article_type":"original","author":[{"last_name":"de Souza","first_name":"R.
