JWST high redshift galaxy observations have a strong tension with Planck CMB measurements
Deng Wang, Yizhou Liu
JWST high redshift galaxy observations predict a higher star formation efficiency than the standard cosmology does, which poses a new tension to CDM. We find that the situation…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Novel Physics with International Pulsar Timing Array: Axionlike Particles, Domain Walls and Cosmic Strings
Deng Wang
After NANOGrav, the IPTA collaboration also reports a strong evidence of a stochastic gravitation wave background. This hint has very important implications for fundamental physics…
Squeezing Cosmological Phase Transitions with International Pulsar Timing Array
Deng Wang
A first-order MeV-scale cosmological phase transition (PT) can generate a peak in the power spectrum of stochastic gravitational wave background around nanohertz frequencies. With…
Testing modified gravity with 21 cm intensity mapping, HI galaxy, cosmic microwave background, optical galaxy, weak lensing, galaxy clustering, type Ia supernovae and gravitational wave surveys
Deng Wang
In modern cosmology, an important task is investigating whether there exists a signal of modified gravity in the universe. Due to the limited resolutions and sensitivities of facil…
4D Gauss-Bonnet gravity: cosmological constraints, tension and large scale structure
Deng Wang, David Mota
We perform correct and reasonable cosmological constraints on the newly proposed 4D Gauss-Bonnet gravity. Using the joint constraint from cosmic microwave background, baryon acoust…
