Despite the remarkable success of the Λ Cold Dark Matter (ΛCDM) cosmological model, a growing discrepancy has emerged (currently measured at the level of ∼ 4 − 6σ) between the value of the Hubble constant H0 measured using the local distance ladder and the value inferred using the cosmic microwave background and galaxy surveys. While a vast array of ΛCDM extensions have been proposed to explain these discordant observations, understanding the (relative) success of these models in resolving the… Expand
Dark Energy at early times and ACT: a larger Hubble constant without late-time priors
Recent observations using the Atacama Cosmology Telescope (ACT) have provided ground-based cosmic microwave background (CMB) maps with higher angular resolution than the Planck satellite. These haveExpand

Cosmology of an Axion-Like Majoron
We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν sector. The majoron φ has a mass mφ ≈ 0.5 eV and a coupling to the τ lepton similar to the one to neutrinos. InExpand
Hints of dark matter-neutrino interactions in Lyman-$\alpha$ data
In this letter we investigate the possibility that dark matter and (massive) neutrinos can interact via a simple, constant cross section. Building on previous numerical efforts, we constrain thisExpand

Alleviating the H0 and σ8 anomalies with a decaying dark matter model
The Hubble tension between the $\Lambda$CDM-model-dependent prediction of the current expansion rate $H_0$ using Planck data and direct, model-independent measurements in the local universe from theExpand
Reconciling H0 tension in a six parameter space?
Consistent observations indicate that some of the important cosmological parameters measured through the local observations are in huge tension with their measurements from the global observationsExpand
Hubble constant hunter’s guide
Measurements of the Hubble constant and, more generally, measurements of the expansion rate and distances over the interval $0lzl1$ appear to be inconsistent with the predictions of the standardExpand
A Simple Phenomenological Emergent Dark Energy Model can Resolve the Hubble Tension
Motivated by the current status of the cosmological observations and significant tensions in the estimated values of some key parameters assuming the standard $\Lambda$CDM model, we propose a simpleExpand
A Dark Sector to Restore Cosmological Concordance
We develop a new phenomenological model that addresses current tensions between observations of the early and late Universe. Our scenario features: (i) a decaying dark energy fluid, which undergoes aExpand
Linear cosmological constraints on 2-body decaying dark matter scenarios and robustness of the resolution to the $S_8$ tension
The ‘S8 tension’ is a longstanding discrepancy between the cosmological and local determination of the amplitude of matter fluctuations, parameterized as S8 ≡ σ8(Ωm/0.3), where σ8 is the root meanExpand
Measurements of the Hubble Constant: Tensions in Perspective
Measurement of the distances to nearby galaxies has improved rapidly in recent decades. The ever-present challenge is to reduce systematic effects, especially as greater distances are probed and theExpand
The Hubble Tension Bites the Dust: Sensitivity of the Hubble Constant Determination to Cepheid Color Calibration
Motivated by the large observed diversity in the properties of extra-galactic extinction by dust, we re-analyse the Cepheid calibration used to infer the local value of the Hubble constant, $H_0$,Expand
Can conformally coupled modified gravity solve the Hubble tension?
The discrepancy between early-Universe inferences and direct measurements of the Hubble constant, known as the Hubble tension, recently became a pressing subject in high precision cosmology. As aExpand
The Local Perspective on the Hubble Tension: Local Structure Does Not Impact Measurement of the Hubble Constant
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%,Expand
