Emergence of the Galaxy Morphology-Star Formation Activity-Clustercentric Radius Relations in Galaxy Clusters
Sungwook E. Hong, Changbom Park, Preetish K. Mishra +7
We investigate when and how the relations of galaxy morphology and star forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy cluste…
Star-formation Properties of z ~ 1 Galaxy Clusters and Groups from Horizon Run 5
Seong-Kook Lee, Changbom Park, Juhan Kim +4
Quiescent galaxies are predominantly observed in local galaxy clusters. However, the fraction of quiescent galaxies in high-redshift clusters significantly varies among different c…
Testing Lyman Alpha Emitters and Lyman-Break Galaxies as Tracers of Large-Scale Structures at High Redshifts
Sang Hyeok Im, Ho Seong Hwang, Jaehong Park +21
We test whether Lyman alpha emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamica…
Identification of Galaxy Protoclusters Based on the Spherical Top-hat Collapse Theory
Jaehyun Lee, Changbom Park, Juhan Kim +7
We propose a new method for finding galaxy protoclusters that is motivated by structure formation theory and also directly applicable to observations. We adopt the conventional def…
Low-Surface-Brightness Galaxies are missing in the observed Stellar Mass Function
Juhan Kim, Jaehyun Lee, Clotilde Laigle +8
We investigate the impact of the surface brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using mock surveys generated from the Horizon Run 5 (HR5) simulation. We…
Formation and Morphology of the First Galaxies in the Cosmic Morning
Changbom Park, Jaehyun Lee, Juhan Kim +8
We investigate the formation and morphological evolution of the first galaxies in the cosmic morning () using the Horizon Run 5 (HR5) simulation. For galaxi…
The Horizon Run 5 Cosmological Hydrodynamic Simulation: Probing Galaxy Formation from Kilo- to Giga-parsec Scales
Jaehyun Lee, Jihye Shin, Owain N. Snaith +12
Horizon Run 5 (HR5) is a cosmological hydrodynamical simulation which captures the properties of the Universe on a Gpc scale while achieving a resolution of 1kpc. Inside the simula…
High-resolution three-dimensional simulations of gas removal from ultrafaint dwarf galaxies. I. Stellar feedback
Donatella Romano, Francesco Calura, Annibale D'Ercole +1
The faintest Local Group galaxies found lurking in and around the Milky Way halo provide a unique test bed for theories of structure formation and evolution on small scales. Deep S…
The time evolution of the Milky Way's oxygen abundance gradient
M. Mollá, Á. I. Díaz, O. Cavichia +5
We study the evolution of oxygen abundance radial gradients as a function of time for the Milky Way Galaxy obtained with our {\sc Mulchem} chemical evolution model. We review the r…
Evolution of Starburst Galaxies in the Illustris Simulation
C. L. Wilkinson, K. A. Pimbblet, J. P. Stott +2
There is a consensus in the literature that starburst galaxies are triggered by inter- action events. However, it remains an open question as to what extent both merging and non-me…
The Role of Stellar Radial Motions in Shaping Galaxy Surface Brightness Profiles
T. Ruiz-Lara, C. G. Few, E. Florido +3
Aims: The physics driving features such as breaks observed in galaxy surface brightness (SB) profiles remains contentious. Here, we assess the importance of stellar radial motions…
The Gaia-ESO Survey: Matching Chemo-Dynamical Simulations to Observations of the Milky Way
B. B. Thompson, C. G. Few, M. Bergemann +39
The typical methodology for comparing simulated galaxies with observational surveys is usually to apply a spatial selection to the simulation to mimic the region of interest covere…
Origin of the Metallicity Distribution in the Thick Disc
Maider S. Miranda, Kate Pilkington, Brad K. Gibson +9
Aims. Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gra…
The imprint of satellite accretion on the chemical and dynamical properties of disc galaxies
T. Ruiz-Lara, C. G. Few, B. K. Gibson +4
Aims: We study the effects of the cosmological assembly history on the chemical and dynamical properties of the discs of spiral galaxies as a function of radius. Methods: We make u…
Feedback from massive stars and gas expulsion from proto-Globular Clusters
F. Calura, C. G. Few, D. Romano +1
Globular clusters are considerably more complex structures than previously thought, harbouring at least two stellar generations which present clearly distinct chemical abundances.…
