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
Observational evidence for a local underdensity in the Universe and its effect on the measurement of the Hubble Constant
For precision cosmological studies it is important to know the local properties of our reference point from which we observe the Universe. In particular for the determination of the Hubble constantExpand
Consistency of the local Hubble constant with the cosmic microwave background
Abstract A significant tension has become manifest between the current expansion rate of our Universe measured from the cosmic microwave background by the Planck satellite and from local distanceExpand
On the Hubble Constant Tension in the SNe Ia Pantheon Sample
The Hubble constant (H 0) tension between Type Ia supernovae (SNe Ia) and Planck measurements ranges from 4 to 6σ. To investigate this tension, we estimate H 0 in the ΛCDM and w0wa CDM (cold darkExpand
New physics in light of the H0 tension: An alternative view
The strong discrepancy between local and early-time (inverse distance ladder) estimates of the Hubble constant H0 could be pointing towards new physics beyond the concordance ΛCDM model. SeveralExpand
CMB Tensions with Low-Redshift H0 and S8 Measurements: Impact of a Redshift-Dependent Type-Ia Supernovae Intrinsic Luminosity
TLDR
The Dark Energy equation of state as a function of redshift is reconstructed, while the impact of type-Ia supernovae (SNIa) redshift-dependent astrophysical systematic effects on these tensions are studied. Expand
Rock 'n' Roll Solutions to the Hubble Tension
Local measurements of the Hubble parameter are increasingly in tension with the value inferred from a $\Lambda$CDM fit to the cosmic microwave background (CMB) data. In this paper, we constructExpand
How does an incomplete sky coverage affect the Hubble Constant variance
We address the $\simeq 4.4\sigma$ tension between local and the CMB measurements of the Hubble Constant using simulated Type Ia Supernova (SN) data-sets. We probe its directional dependence by meansExpand
