A Universal Relation Between Primordial Density-Potential Cross-correlation Coefficient and Spin Factor Distribution
Jun-Sung Moon, Jounghun Lee, Juhan Kim
The authors derive an analytic expression that relates the mean and variance of the primordial spin factor of dark matter halos to the initial density‑potential cross‑correlation c…
Void spin distribution as a powerful probe of
Geonwoo Kang, Jounghun Lee
We present a numerical proof of the concept that the void spin distributions can provide a tight constraint on the amplitude of matter density fluctuation on the scale of $8\,h^{-1…
Dependence of Galaxy Stellar Properties on the Primordial Spin Factor
Jun-Sung Moon, Jounghun Lee
We present a numerical discovery that the observable stellar properties of present galaxies retain significant dependences on the primordial density and tidal fields. Analyzing the…
The dependence of halo bias on the protohalo shape alignment with the initial tidal field
Jounghun Lee, Jun-Sung Moon
We present a numerical evidence supporting the primordial origin of secondary halo bias even on the galactic mass scale. Analyzing the data from the IllustrisTNG 300-1 simulations,…
