The dark matter halo mass function in the cosmology at all times and over all scales -- from planetary to galaxy cluster masses
Haonan Zheng, Sownak Bose, Carlos S. Frenk +7
The dark matter halo mass function is one of the most fundamental predictions of structure formation theory and cosmological simulations. We present the full halo mass function in…
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…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…
Particle loads for cosmological simulations with equal-mass dark matter and baryonic particles
Shihong Liao, Yizhou Liu, Haonan Zheng +5
Traditional cosmological hydrodynamical simulations usually assume equal-numbered but unequal-mass dark matter and baryonic particles, which can lead to spurious collisional heatin…
Prospects for detecting cosmic filaments in Lyman-alpha emission across redshifts
Yizhou Liu, Liang Gao, Shihong Liao +1
The standard CDM cosmological model predicts that a large amount of diffuse neutral hydrogen distributes in cosmic filaments, which could be mapped through Lyman-alpha (Ly$…
The mass accretion history of dark matter haloes down to Earth mass
Yizhou Liu, Liang Gao, Sownak Bose +6
We take advantage of the unprecedented dynamical range provided by the "Cosmic-Zoom" project to study the mass accretion history (MAH) of present-day dark matter haloes over the en…
