Are James Webb Space Telescope Observations Consistent with Warm Dark Matter?

Hoeneisen, Bruce

We compare observed with predicted distributions of galaxy stellar masses $M_*$ and galaxy rest-frame ultra-violet luminosities per unit bandwidth $L_{UV}$, in the redshift range $z = 2$ to 13. The comparison is presented as a function of the comoving warm dark matter free-streaming cut-off wavenumber $k_{fs}$. For this comparison the theory is a …
