Primordial Black Hole Mass Function with Mass Gap
Xiao-Ming Bi, Lu Chen, Ke Wang
Primordial black holes (PBHs) are mainly characterized by their mass function, in which there may be some huge suppression for certain mass spans. If this is the case, the absence…
Consistency test of the fine-structure constant from the whole ionization history
Ke Wang, Lu Chen
In cosmology, the fine-structure constant can affect the whole ionization history. However, the previous works confine themselves to the recombination epoch and give various strong…
Does the Reionization Model Influence the Constraints on Dark Matter Decay or Annihilation?
Lu Chen, Ke Wang
If dark matter decay or annihilate, a large amount of energy and particles would be released into the cosmic plasma. Therefore, they could modify the thermal and ionization history…
Constraints on Multicomponent Dark Energy from Cosmological Observations
Ke Wang, Lu Chen
Dark energy (DE) plays an important role in the expansion history of our universe. But we only got limited knowledge about its nature and properties after decades of study.In most…
Constraints on Newton's Constant from Cosmological Observations
Ke Wang, Lu Chen
Newton's constant has observational effects on both the CMB power spectra and the light curves of SNIa. We use Planck data, BAO data and the SNIa measurement to constrain the varyi…
Distance Priors from Planck Final Release
Lu Chen, Qing-Guo Huang, Ke Wang
We present the distance priors from the finally released data in 2018. The uncertainties are around smaller than those from $Planck…
