Is Abell 2261 a fossil galaxy cluster in a transitional dynamical state?
Hyowon Kim, Jongwan Ko, Rory Smith +5
Abell 2261 (A2661) is a well-studied fossil cluster, but previous studies give contradictory results on its dynamical states, such as its X-ray central entropy and magnitude gap. T…
Searching for MgII absorbers in and around galaxy clusters
Jong Chul Lee, Ho Seong Hwang, Hyunmi Song
To study environmental effects on the circumgalactic medium (CGM), we use the samples of redMaPPer galaxy clusters, background quasars and cluster galaxies from the SDSS. With ~82…
Lyman-alpha radiative transfer: Modeling spectrum and surface brightness profile of Lyman-alpha emitting galaxies at z=3-6
Hyunmi Song, Kwang-Il Seon, Ho Seong Hwang
We perform Lyman-alpha radiative transfer calculations for reproducing Lyman-alpha properties of star-forming galaxies at high redshifts. We model a galaxy as a halo in which the d…
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…
Evolution of star formation rate-density relation over cosmic time in a simulated universe: the observed reversal reproduced
Ho Seong Hwang, Jihye Shin, Hyunmi Song
We use the IllustrisTNG cosmological hydrodynamical simulation to study the evolution of star formation rate (SFR)-density relation over cosmic time. We construct several samples o…
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…
