چکیده

By focusing on the simple $w\neq-1$ extension to $\Lambda$CDM, we assess which epoch(s) possibly source $H_0$-tension. We consider Cosmic Microwave Background (CMB) data in three possible ways: $i)$ complete CMB data; $ii)$ excluding $l<30$ temperature and polarization likelihoods; $iii)$ imposing early universe priors, that disentangle late time physics. Through a joint analysis with low-redshift supernovae type-Ia gravitationally lensed delay datasets, {and neglecting galaxy clustering Baryonic Acoustic Oscillation (BAO) data}, find inclusion of priors is consistent local estimate $H_0$ while low-$l$+lowE likelihoods mildly relaxes tension. This contrast analyses data. Our implementation contrasting effect different shows information from when decoupled late-times physics could be agreement higher value $H_0$. {We also no evidence for dark energy model using only within Finally BAO redshift ranges perform inverse distance ladder analysis, modifications, being perfectly capable alleviating $H_0$-tension including data, would at odds Ly-$\alpha$ due difference $r_{\rm d}\, vs.\, H_0$ correlation between two datasets.} therefore infer speculate estimates originate modeling late-time analysis. turn recasts as an CMB, instead current early-time vs. perspective.

Phenomenology of Hybrid Scenarios of Neutrino Dark Energy

We study the phenomenology of hybrid scenarios of neutrino dark energy, where in addition to a so-called Mass Varying Neutrino (MaVaN) sector a cosmological constant (from a false vacuum) is driving the accelerated expansion of the universe today. For general power law potentials we calculate the effective equation of state parameter weff (z) in terms of the neutrino mass scale. Due to the inte...
