Radial velocity statistics of cosmic voids as a probe of interacting dark energy

Kin Ho Luo, Ming-chung Chu, Kwan Chuen Chan +1

Due to their vast sizes and extremely low densities, the dynamics of cosmic voids are largely decoupled from complex, small-scale baryonic physics and are highly sensitive to the b…

Measuring neutrino mass and asymmetry through galaxy pairwise peculiar velocity

Wangzheng Zhang, Ming-chung Chu, Shihong Liao

Cosmic neutrinos are among the most abundant fermions in the Universe, yet the values of their masses and chemical potentials remain uncertain. In this Letter, we present the first…

PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy

Himanish Ganjoo, Yann Rasera, Emilio Bellini +18

Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…

Halo abundance and clustering in cosmologies with massive and asymmetric neutrinos

Yizhou Liu, Wangzheng Zhang, Shihong Liao +1

Neutrinos are the most abundant fermions in the Universe and influence the formation of large-scale structure through both their non-zero masses and a possible chemical potential w…

Probing the Type 3 interacting dark-energy model using matter pairwise velocity

Kin Ho Luo, Ming-chung Chu, Wangzheng Zhang

Dark sector interactions can be explored via the so-called Type 3 model where dark matter and dark energy exchange momentum only, so as to minimize deviations from the CDM backg…

Impact of light sterile neutrinos on cosmological large scale structure

Rui Hu, Ming-chung Chu, Shek Yeung +1

Sterile neutrinos with masses on the scale are promising candidates to account for the origin of neutrino mass and the reactor neutrino anomalies. The mixing between…

Measuring the Hubble constant through the galaxy pairwise peculiar velocity

Wangzheng Zhang, Ming-chung Chu, Shihong Liao +2

The Hubble constant , the current expansion rate of the universe, is one of the most important parameters in cosmology. The cosmic expansion regulates the mutually approaching…

Refitting cosmological data with neutrino mass and degeneracy

Shek Yeung, Wangzheng Zhang, Ming-chung Chu

A simple and natural extension of the standard Lambda cold dark matter (CDM) model is to allow relic neutrinos to have finite chemical potentials. We confront this CDM mod…

Measuring neutrino mass and asymmetry with matter pairwise velocities

Wangzheng Zhang, Ming-chung Chu, Rui Hu +2

Neutrinos are believed to be the most abundant fermions in the Universe, but their masses are unknown, except for being non-zero but much smaller than other fermions. Cosmological…
