A low value of in tension with the distance ladder from Megamasers using peculiar velocity reconstruction
Richard Watkins, Hume A. Feldman
Megamaser distances can be measured without using the traditional distance ladder. As such, they provide an independent probe of the local expansion rate, quantified by the Hubble…
Consistency of DES and DESI distances and the Standard Cosmological Model
Richard Watkins, Cordelia Trueax, Hume A. Feldman
We test the consistency of the cosmic distance-redshift relation inferred from the cosmic microwave background (CMB), the Dark Energy Spectroscopic Instrument (DESI) baryon acousti…
The peculiar velocity correlation function of the Cosmicflows-4 catalog
Yuyu Wang, Hume A. Feldman, Richard Watkins +1
We present an analysis of the parallel peculiar velocity correlation function using data from the Cosmicflows-4 (CF4) survey. CF4 significantly extends the depth of the peculiar ve…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
