We use the largest sample to date of spectroscopic SN Ia distances and redshifts to look for evidence in the Hubble diagram of large scale outflows caused by local voids suggested to exist at z 20%, where the density contrast delta = Delta rho /rho) proposed in some galaxy count studies, and find no evidence of a change in the Hubble constant corresponding to a void with a sharp edge in the redshift range 0.023<z<0.15. With empirical precision of sigma_H_0 = 0.60%, we conclude that the distance… Expand

Local resolution of the Hubble tension: The impact of screened fifth forces on the cosmic distance ladder
The discrepancy between the values of the Hubble constant H0 derived from the local distance ladder and the cosmic microwave background provides a tantalizing hint of new physics. We explore aExpand
Local Hole revisited: evidence for bulk motions and self-consistent outflow
We revisit our mapping of the ‘Local Hole’, a large underdensity in the local galaxy redshift distribution that extends out to redshift z ≈ 0.05 and a potential source of outflows that may perturbExpand
Galaxy-lens determination of H0: constraining density slope in the context of the mass sheet degeneracy
Gravitational lensing offers a a competitive method to measure $H_0$ with the goal of 1\% precision. A major obstacle comes in the form of lensing degeneracies, such as the mass sheet degeneracyExpand
Alleviating tension in ΛCDM and the local distance ladder from first principles with no free parameters
At increasing levels of confidence, Λ cold dark matter (ΛCDM) is challenged by tension in the Hubble parameter H0 with respect to the local distance ladder. We introduce a new approach toExpand
Observational evidence for a local underdensity in the Universe and its effect on the measurement of the Hubble constant

A Cosmological Underdensity Does Not Solve the Hubble Tension
A potential solution to the Hubble tension is the hypothesis that the Milky Way is located near the center of a matter underdensity. We model this scenario through the Lemâıtre–Tolman–Bondi formalismExpand

We have carefully studied how local measurements of the Hubble constant, $H_0$, can be influenced by a variety of different parameters related to survey geometry, depth, and size, as well as observerExpand

How does the cosmic large-scale structure bias the Hubble diagram?
The Hubble diagram is one of the cornerstones of observational cosmology. It is usually analysed assuming that, on average, the underlying relation between magnitude and redshift matches theExpand
