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…
SN Ia Population Machine. I. A Unified Cosmological Simulation-Binary Synthesis Framework Establishing Non-universal Delay-time Distributions and Cosmic Progenitor-channel Dominance Crossover
Suk-Jin Yoon, Inhyuk Park, Woong-Bae G. Zee +6
We present a forward-modeling framework for synthesizing Type Ia supernova (SN Ia) populations by coupling cosmological hydrodynamic simulations to binary population synthesis (BPS…
Galaxy Spin Alignment with Tidal Fields in the SDSS-IV MaNGA Survey
Jun-Sung Moon, Teppei Okumura
The tidal torque theory (TTT) predicts that galaxy spins are correlated with the surrounding tidal field, reflecting how angular momentum is acquired during structure formation. We…
Living with Neighbors. V. Better-aligned Spiral+Spiral Galaxy Pairs Show Stronger Star Formation
Woong-Bae G. Zee, Jun-Sung Moon, Sanjaya Paudel +1
Enhanced star formation (SF) with star-forming neighboring galaxies bolsters hydrodynamical contributions during paired interactions. Although the relative spin orientation between…
An Observed Evidence for the Primordial Origin of Galaxy Sizes
Jun-Sung Moon, Jounghun Lee
We present an observational evidence supporting the scenario that the protogalactic angular momenta play an important role in molding the optical sizes of present galaxies. Analyzi…
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…
