A Universal Relation Between Primordial Density-Potential Cross-correlation Coefficient and Spin Factor Distribution
Jun-Sung Moon, Jounghun Lee, Juhan Kim
Recent studies have revealed that the key properties of visible galaxies like their optical sizes, stellar ages, star formation rates and morphologies are closely linked with the a…
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,…
Galaxy Spin Transition Driven by the Misalignments between the Protogalaxy Inertia and Initial Tidal Tensors
Jun-Sung Moon, Jounghun Lee
A numerical detection of the -driven transition of galaxy spins is presented, where is the degree of misalignment between the initial tidal field and protogalaxy inertia ten…
Mutual information between galaxy properties and the initial predisposition
Jun-Sung Moon, Jounghun Lee
The immense diversity of the galaxy population in the universe is believed to stem from their disparate merging and star formation histories, and multi-scale influences of diverse…
An Observed Transition of Galaxy Spins on the Void Surfaces
Jounghun Lee, Jun-Sung Moon
In the linear theory, the galaxy angular momentum vectors which originate from the initial tidal interactions with surrounding matter distribution intrinsically develop perpendicul…
Reoriented Memory of Galaxy Spins for the Early Universe
Jun-Sung Moon, Jounghun Lee
Galaxy spins are believed to retain the initially acquired tendency of being aligned with the intermediate principal axes of the linear tidal field, which disseminates a prospect o…
The Density Parity Model for the Evolution of the Subhalo Inner Spin Alignments with the Cosmic Web
Jun-Sung Moon, Jounghun Lee
We develop a new model within which the radius-dependent transition of the subhalo inner spins with respect to the cosmic web and the variation of the transition threshold radius (…
Radius-Dependent Spin Transition of Dark Matter Halos
Jun-Sung Moon, Jounghun Lee
A numerical detection of the radius-dependent spin transition of dark matter halos is reported. Analyzing the data from the IllustrisTNG simulations, we measure the halo spin vecto…
Detection of the Mass-Dependent Dual-Type Transition of Galaxy Spins in IllustrisTNG Simulations
Jounghun Lee, Jun-Sung Moon, Suho Ryu +1
A numerical detection of the mass-dependent spin transition of the galaxies is presented. Analyzing a sample of the galaxies with stellar masses in the range of $10^{9}< (M_{\star}…
Demographics of Sloan Digital Sky Survey galaxies along the Hubble sequence
Kyuseok Oh, Hyunseop Choi, Hong-Geun Kim +2
We present the statistical properties of a volume-limited sample of 7,429 nearby (z = 0.033 - 0.044) galaxies from the Sloan Digital Sky Survey Data Release 7. Our database include…
