Early-type Dwarf Galaxies in the Local Universe. Evidence of Ex-situ Growth
Sanjaya Paudel, Suk-Jin Yoon, Jun-Sung Moon +1
We report the discovery of a rare early-type dwarf galaxy (dE), SDSS J125651.47+163024.2 (hereafter dE1256), possessing a tidal feature that was likely built up by accretion of an…
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…
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…
Merger Effects on the Spin and Shape Alignments of Galaxy Stellar, Cold and Hot Gas, and Dark Matter Components
Jounghun Lee, Jun-Sung Moon
We present a numerical evidence supporting the scenario that the peculiar alignments of the galaxy stellar spins with the major principal axes of the local tidal tensors are produc…
