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…
Warped Disk Galaxies. I. Linking U type Warps in Groups/Clusters to Jellyfish Galaxies
Woong-Bae G. Zee, Suk-Jin Yoon, Jun-Sung Moon +3
arped disk galaxies are classified into two morphologies: S- and U-types. Conventional theories routinely attribute both types to galactic tidal interaction and/or gas accretion, b…
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…
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…
Living with Neighbors. III. Scrutinizing the SpinOrbit Alignment of Interacting Dark Matter Halo Pairs
Sung-Ho An, Juhan Kim, Jun-Sung Moon +1
We present that the spinorbit alignment (SOA; i.e., the angular alignment between the spin vector of a halo and the orbital angular momentum vector of its neighbor) provides an…
Living with Neighbors. II. Statistical Analysis of Flybys and Mergers of Dark Matter Halos in Cosmological Simulations
Sung-Ho An, Juhan Kim, Jun-Sung Moon +1
We present a statistical analysis of flybys of dark matter halos compared to mergers using cosmological -body simulations. We mainly focus on gravitationally interacting target…
Living with Neighbors. I. Observational Clues to Hydrodynamic Impact of Neighboring Galaxies on Star Formation
Jun-Sung Moon, Sung-Ho An, Suk-Jin Yoon
Galaxies in pairs show enhanced star formation (SF) compared to their counterparts in isolation, which is often explained by the tidal effect of neighboring galaxies. Recent observ…
Formation of Warped Disks by Galactic Fly-by Encounters. I. Stellar Disks
Jeonghwan H. Kim, Sebastien Peirani, Sungsoo Kim +3
Warped disks are almost ubiquitous among spiral galaxies. Here we revisit and test the `fly-by scenario' of warp formation, in which impulsive encounters between galaxies are respo…
