Physically-motivated priors in the local distance ladder significantly reduce the Hubble tension
Marcus Högås, Edvard Mörtsell
Determinations of the Hubble constant based on the local distance ladder remain in significant tension with early-Universe inferences from the cosmic microwave background. While th…
Constraining Fifth Forces using the Local Distance Ladder: Implications for the Hubble Tension
Marcus Högås, Edvard Mörtsell, Harry Desmond +1
We revisit the local distance ladder measurement of the Hubble constant in models where gravity is modified by a fifth force, an additional long-range interaction. In many such the…
Analytic Marginalization over Binary Variables in Physics Data
Marcus Högås, Edvard Mörtsell
In many data analyses, each measurement may come with a simple yes/no correction; for example, belonging to one of two populations or being contaminated or not. Ignoring such binar…
Reassessing the Cepheid-based distance ladder: implications for the Hubble constant
Marcus Högås, Edvard Mörtsell
The Hubble constant () is a key parameter in cosmology, yet its precise value remains contentious due to discrepancies between early- and late-universe measurement methods, a…
2D BAO vs 3D BAO: solving the Hubble tension with an alternative cosmological model
Sowmaydeep Dwivedi, Marcus Högås
Ordinary 3D Baryon Acoustic Oscillations (BAO) data are model-dependent, requiring the assumption of a cosmological model to calculate comoving distances during data reduction. Thr…
