A New Rarity Assessment of the `Disk of Satellites': the Milky Way System Is the Exception Rather than the Rule in the CDM Cosmology
Chanoul Seo, Suk-Jin Yoon, Sanjaya Paudel +2
The majority of satellite galaxies around the Milky Way (MW) show disk-like distributions (the disk of satellites; DoS), which is a small-scale problem of the CDM cosmology. The…
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,…
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…
