An efficient and robust method to estimate halo concentration
Kai Wang, H. J. Mo, Yangyao Chen +1
We propose an efficient and robust method to estimate the halo concentration based on the first moment of the density distribution, which is $R_1\equiv \int_0^{r_{\rm vir}}4πr^3ρ(r…
Dynamical hotness, star formation quenching and growth of supermassive black holes
Hui Hong, Huiyuan Wang, H. J. Mo +8
A stellar system is dynamically hot when its kinetic energy is dominated by random motion represented by the velocity dispersion . We use MaNGA data to obtain in…
Massive Dark Matter Halos at High Redshift: Implications for Observations in the JWST Era
Yangyao Chen, H. J. Mo, Kai Wang
The presence of massive galaxies at high as recently observed by JWST appears to contradict the current CDM cosmology. Here we aim to alleviate this tension by incorporating…
A Conditional Abundance Matching Method of Extending Simulated Halo Merger Trees to Resolve Low-Mass Progenitors and Sub-halos
Yangyao Chen, H. J. Mo, Cheng Li +3
We present an algorithm to extend subhalo merger trees in a low-resolution dark-matter-only simulation by conditionally matching them to those in a high-resolution simulation. The…
