Small-Scale Dynamical Coherence Accompanied with Galaxy Conformity
Joon Hyeop Lee, Mina Pak, Hye-Ran Lee
The discovery of the coherence between galaxy rotation and neighbor motion in 1-Mpc scales has been reported recently. Following up the discovery, we investigate whether the neighb…
Mysterious Coherence in Several-Megaparsec Scales Between Galaxy Rotation and Neighbor Motion
Joon Hyeop Lee, Mina Pak, Hyunmi Song +3
In our recent report, observational evidence supports that the rotational direction of a galaxy tends to be coherent with the average motion of its nearby neighbors within 1 Mpc. W…
Stellar populations of nine passive spiral galaxies from the CALIFA survey: are they progenitors of S0s?
Mina Pak, Joon Hyeop Lee, Hyunjin Jeong +3
We investigate the stellar population properties of passive spiral galaxies in the CALIFA survey. Nine spiral galaxies that have NUV-r > 5 and no/weak nebular emission lines in the…
Galaxy Rotation Coherent with the Motions of Neighbors: Discovery of Observational Evidence
Joon Hyeop Lee, Mina Pak, Hye-Ran Lee +1
We present our discovery of observational evidence for the coherence between galaxy rotation and the average line-of-sight motion of neighbors. We use the Calar Alto Legacy Integra…
Color Dispersion as an Indicator of Stellar Population Complexity: Insights from the Pixel Color-Magnitude Diagrams of 32 Bright Galaxies in Abell 1139 and Abell 2589
Joon Hyeop Lee, Mina Pak, Hye-Ran Lee +1
We investigate the properties of bright galaxies with various morphological types in Abell 1139 and Abell 2589, using the pixel color-magnitude diagram (pCMD) analysis technique. T…
Small-Scale Conformity of the Virgo Cluster Galaxies
Hye-Ran Lee, Joon Hyeop Lee, Hyunjin Jeong +1
We investigate the small-scale conformity in color between bright galaxies and their faint companions in the Virgo cluster. Cluster member galaxies are spectroscopically determined…
Measurable Relationship Between Bright Galaxies and Their Faint Companions in WHL J085910.0+294957, a Galaxy Cluster at z = 0.30: Vestiges of Infallen Groups?
Joon Hyeop Lee, Hye-Ran Lee, Minjin Kim +8
The properties of satellite galaxies are closely related to their host galaxies in galaxy groups. In cluster environments, on the other hand, the interaction between close neighbor…
