How the Galaxy Stellar Spins Acquire a Peculiar Tidal Connection?
Jounghun Lee, Jun-Sung Moon, Suk-Jin Yoon
We explore how the galaxy stellar spins acquire a peculiar tendency of being aligned with the major principal axes of the local tidal fields, in contrast to their DM counterparts w…
Living with Neighbors. IV. Dissecting the SpinOrbit Alignment of Dark Matter Halos: Interacting Neighbors and the Local Large-scale Structure
Sung-Ho An, Juhan Kim, Jun-Sung Moon +1
Spinorbit alignment (SOA; i.e., the vector alignment between the halo spin and the orbital angular momentum of neighboring halos) provides an important clue to how galactic angu…
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}…
Living with Neighbors. III. The Origin of the SpinOrbit Alignment of Galaxy Pairs: A Neighbor versus the Large-scale Structure
Jun-Sung Moon, Sung-Ho An, Suk-Jin Yoon
Recent observations revealed a coherence between the spin vector of a galaxy and the orbital motion of its neighbors. We refer to the phenomenon as "the spinorbit alignment (SOA…
