Recent Cosmic Microwave Background (CMB) temperature and polarization anisotropy measurements from the Planck mission have significantly improved previous constraints on the neutrino masses as well as the bounds on extended models with massless or massive sterile neutrino states. However, due to parameter degeneracies, additional low redshift priors are mandatory in order to sharpen the CMB neutrino bounds. We explore here the role of different priors on low redshift quantities, such as the… 
Neutrino masses and beyond- ΛCDM cosmology with LSST and future CMB experiments
Cosmological measurements over the next decade will enable us to shed light on the content and evolution of the Universe. Complementary measurements of the Cosmic Microwave Background (CMB) and
Updated bounds on sum of neutrino masses in various cosmological scenarios
We present strong bounds on the sum of three active neutrino masses (∑mν) using selected cosmological datasets and priors in various cosmological models. We use the following baseline datasets:
Constraints on the sum of neutrino masses using cosmological data including the latest extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample
We investigate the constraints on the sum of neutrino masses ( Σ m ν ) using the most recent cosmological data, which combines the distance measurement from baryonic acoustic oscillation in the
Neutrino mass without cosmic variance
Measuring the absolute scale of the neutrino masses is one of the most exciting opportunities available with near-term cosmological data sets. Two quantities that are sensitive to neutrino mass,
A tale of two modes: neutrino free-streaming in the early universe
We present updated constraints on the free-streaming nature of cosmological neutrinos from cosmic microwave background (CMB) temperature and polarization power spectra, baryonic acoustic oscillation
Neutrino masses and their ordering: global data, priors and models
We present a full Bayesian analysis of the combination of current neutrino oscillation, neutrinoless double beta decay and Cosmic Microwave Background observations. Our major goal is to carefully

We investigate two dark energy cosmological models (i.e., the ΛCDM and ϕCDM models) with massive neutrinos assuming two different neutrino mass hierarchies in both the spatially flat and non-flat
Neutrino mass priors for cosmology from random matrices
Cosmological measurements of structure are placing increasingly strong constraints on the sum of the neutrino masses, $\Sigma m_\nu$, through Bayesian inference. Because these constraints depend on
Neutrino Mass Ordering from Oscillations and Beyond: 2018 Status and Future Prospects
The ordering of the neutrino masses is a crucial input for a deep understanding of flavor physics, and its determination may provide the key to establish the relationship among the lepton masses and
