Cosmology with Tully-Fisher HI Galaxy Surveys
Joël Mayor, Anthony Carr, Khaled Said +7
The SKA Observatory will enable measurements of the Tully-Fisher relation for statistical samples of HI selected galaxies out to unprecedented depths and redshifts thanks to its un…

The DESI DR1 Peculiar Velocity Survey: growth rate measurements from the maximum likelihood fields method
Y. Lai, C. Howlett, J. Aguilar +60
We present the constraint on the growth rate of structure from the combination of DESI DR1 BGS sample, Fundamental Plane, and Tully-Fisher peculiar velocity catalogues using the ma…

Generalized framework for likelihood-based field-level inference of growth rate from velocity and density fields
Corentin Ravoux, Bastien Carreres, Damiano Rosselli +8
Measuring the growth rate of large-scale structures (f) as a function of redshift has the potential to break degeneracies between modified gravity and dark energy models, when comb…
