Radial velocity statistics of cosmic voids as a probe of interacting dark energy
Kin Ho Luo, Ming-chung Chu, Kwan Chuen Chan +1
The paper uses N-body simulations to show that the radial velocity and velocity‑dispersion profiles of cosmic voids change noticeably in a Type‑3 interacting dark‑energy model, mak…
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…
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 back…
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…
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…
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…
