Evidence for Cosmological Massive Neutrinos
Deng Wang
A key question in cosmology is whether massive neutrinos exist on cosmic scales. Current cosmological observations have severely compressed the viable range for neutrino masses and…
Scale and redshift dependent limits on cosmic neutrino properties
Deng Wang, Olga Mena, Eleonora Di Valentino +1
Cosmological neutrino mass and abundance measurements are reaching unprecedented precision. Testing their stability versus redshift and scale is a crucial issue, as it can serve as…
Primordial Gravitational Waves 2024
Deng Wang
Primordial gravitational waves have crucial implications for the origin of the universe and fundamental physics. Using currently available cosmic microwave background data from Pla…
Updating neutrino mass constraints with Background measurements
Deng Wang, Olga Mena, Eleonora Di Valentino +1
Low-redshift probes, such as Baryon Acoustic Oscillations (BAO) and Supernovae Ia luminosity distances, have been shown to be crucial for improving the bounds on the total neutrino…
The Self-Consistency of DESI Analysis and Comment on "Does DESI 2024 Confirm CDM?"
Deng Wang
We demonstrate that the constraints on the evolution of dark energy implemented by the DESI collaboration may be insufficient or incomplete using their own BAO data. Using large en…
Constraining Cosmological Physics with DESI BAO Observations
Deng Wang
The DESI year one observations can help probe new physics on cosmological scales. In light of the latest DESI BAO measurements, we constrain five popular cosmological scenarios inc…
Lighting Dark Ages with Tomographic ISW Effect
Deng Wang, Olga Mena
The integrated Sachs-Wolfe effect (ISW) describes how CMB photons pick up a net blue or redshift when traversing the time-varying gravitational potentials between the last scatteri…
Constraining Cosmological Phase Transitions with Chinese Pulsar Timing Array Data Release 1
Deng Wang
The Chinese Pulsar Timing Array (CPTA) collaboration has recently reported the observational evidence of a stochastic gravitational wave background. In light of the latest CPTA obs…
Dynamical dark energy can explain the anomalous matter density fluctuation at
Deng Wang
Recently, under the standard cosmological model, a new growth tension between the Planck-2018 observation and the combined observation of cosmic microwave background lensing and ga…
Testing the Hubble law with Pantheon+
Deng Wang
The Hubble law (HL) governs the low-redshift (low-z) evolution of the distance of an object. However, there is a lack of an investigation of its validity and effective radius for a…
Pantheon+ tomography and Hubble tension
Deng Wang
The recently released Type Ia supernovae (SNe Ia) sample, Pantheon+, is an updated version of Pantheon and has very important cosmological implications. To explore the origin of th…
Pantheon+ constraints on dark energy and modified gravity: An evidence of dynamical dark energy
Deng Wang
We use the latest Type Ia supernovae sample Pantheon+ to explore new physics on cosmic scales. Specifically, in light of this new sample, we constrain the interacting dark energy a…
Can gravity relieve and tensions?
Deng Wang
To investigate whether gravity can relieve current and tensions, we constrain the Hu-Sawicki gravity with Planck-2018 cosmic microwave background and reds…
Dark Energy Constraints in light of Pantheon SNe Ia, BAO, Cosmic Chronometers and CMB Polarization and Lensing Data
Deng Wang
To explore whether there is new physics going beyond the standard cosmological model or not, we constrain seven cosmological models by combining the latest and largest Pantheon Typ…
