New $H(z)$ measurement at Redshift = 0.12 with DESI Data Release 1

Lei Lei, Yi-Zhong Fan, Ze-fan Wang

New measurement of the Hubble parameter at redshift 0.12 from stellar ages of DESI galaxies gives 71.33 km/s/Mpc.

Claims

C1strongest claim

we derive a new measurement of H(z=0.12)=71.33 ± 4.20 km s^{-1} Mpc^{-1}, which is well consistent with those derived in other ways.

C2weakest assumption

The full-spectrum fitting with BAGPIPES yields accurate, cosmology-independent stellar ages for the selected massive passively evolving galaxies that can be directly converted into an H(z) measurement.

C3one line summary

New measurement of the Hubble parameter H(z=0.12) = 71.33 ± 4.20 km s^{-1} Mpc^{-1} obtained from cosmology-independent stellar ages of passive galaxies in DESI Data Release 1.
