UV absorption lines and their potential for tracing the Lyman continuum escape fraction
V. Mauerhofer, A. Verhamme, J. Blaizot +4
The neutral intergalactic medium above redshift 6 is opaque to ionizing radiation, therefore one needs indirect measurements of the escape fraction of ionizing photons from galaxie…
Star-Gas Misalignment in Galaxies: II. Origins Found from the Horizon-AGN Simulation
Donghyeon J. Khim, Sukyoung K. Yi, Christophe Pichon +5
There have been many studies aiming to reveal the origins of the star-gas misalignment found in galaxies, but there still is a lack of understanding of the contribution from each f…
Difference in chemical composition between the bright and faint red clump stars in the Milky Way bulge
Dongwook Lim, Young-Wook Lee, Andreas Koch +7
The double red clump (RC) observed in color-magnitude diagrams of the Milky Way bulge is at the heart of the current debate on the structure and formation origin of the bulge. This…
Nonlinear Color-Metallicity Relations of Globular Clusters. IX. Different Radial Number Density Profiles between Blue and Red Clusters
Sang-Yoon Lee, Chul Chung, Suk-Jin Yoon
The optical colors of globular clusters (GCs) in most large early-type galaxies are bimodal. Blue and red GCs show a sharp difference in the radial profile of their surface number…
Multiple stellar populations along the red Horizontal Branch and Red Clump of Globular Clusters
Emanuele Dondoglio, Antonino P. Milone, Edoardo P. Lagioia +5
We exploit multi-band Hubble Space Telescope photometry to investigate multiple populations (MPs) along the red horizontal branches (HBs) and red clumps of fourteen metal-rich Glob…
The MAGPI Survey -- science goals, design, observing strategy, early results and theoretical framework
C. Foster, J. T. Mendel, C. D. P. Lagos +40
We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on ESO/VLT. MAGPI is designed to study the physical dri…
Dual Effects of Ram Pressure on Star Formation in Multi-phase Disk Galaxies with Strong Stellar Feedback
Jaehyun Lee, Taysun Kimm, Harley Katz +3
We investigate the impact of ram pressure stripping due to the intracluster medium (ICM) on star-forming disk galaxies with a multi-phase interstellar medium (ISM) maintained by st…
WISDOM project -- VI. Exploring the relation between supermassive black hole mass and galaxy rotation with molecular gas
Mark D. Smith, Martin Bureau, Timothy A. Davis +6
Empirical correlations between the masses of supermassive black holes (SMBHs) and properties of their host galaxies are well-established. Among these is the correlation with the fl…
YZiCS: On the Mass Segregation of Galaxies in Clusters
Seonwoo Kim, Emanuele Contini, Hoseung Choi +5
Mass segregation, a tendency of more massive galaxies being distributed closer to the cluster center, is naturally expected from dynamical friction, but its presence is still contr…
Exemplary Merging Clusters: Weak-lensing and X-ray Analysis of the Double Radio Relic Merging Galaxy Clusters MACS 1752.0+4440 and ZWCL 1856.8+6616
Kyle Finner, Kim HyeongHan, M. James Jee +8
The investigation of merging galaxy clusters that exhibit radio relics is strengthening our understanding of the formation and evolution of galaxy clusters, the nature of dark matt…
Dark-matter-deficient dwarf galaxies form via tidal stripping of dark matter in interactions with massive companions
R. A. Jackson, S. Kaviraj, G. Martin +11
In the standard Lambda-CDM paradigm, dwarf galaxies are expected to be dark-matter-rich, as baryonic feedback is thought to quickly drive gas out of their shallow potential wells a…
Further evidence for significant luminosity evolution in supernova cosmology
Young-Wook Lee, Chul Chung, Yijung Kang +1
Supernova (SN) cosmology is based on the assumption that the corrected luminosity of SN Ia would not evolve with redshift. Recently, our age dating of stellar populations in early-…
Exploring the origin of thick disks using the NewHorizon and Galactica simulations
Minjung J. Park, Sukyoung K. Yi, Sebastien Peirani +8
Ever since a thick disk was proposed to explain the vertical distribution of the Milky Way disk stars, its origin has been a recurrent question. We aim to answer this question by i…
Introducing the NewHorizon simulation: Galaxy properties with resolved internal dynamics across cosmic time
Yohan Dubois, Ricarda Beckmann, Frédéric Bournaud +13
Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics. However, us…
Yonsei Evolutionary Population Synthesis (YEPS) Model. III. Surface Brightness Fluctuation of Normal and Helium-enhanced Simple Stellar Populations
Chul Chung, Suk-Jin Yoon, Hyejeon Cho +2
We present an evolutionary population synthesis model of the surface brightness fluctuation (SBF) for normal and He-enriched simple stellar populations (SSPs). While our SBF model…
Beyond halo mass: quenching galaxy mass assembly at the edge of filaments
Hyunmi Song, Clotilde Laigle, Ho Seong Hwang +6
We examine how the mass assembly of central galaxies depends on their location in the cosmic web. The HORIZON-AGN simulation is analysed at z~2 using the DISPERSE code to extract m…
Compact elliptical galaxies in different local environments: a mixture of galaxies with different origins?
Suk Kim, Hyunjin Jeong, Soo-Chang Rey +4
We present the stellar populations of 138 compact elliptical galaxies (cEs) in the redshift range of using the Sloan Digital Sky Survey (SDSS) DR12. Our cEs are divided…
The Blue Compact Dwarf Galaxy VCC 848 Formed by Dwarf-Dwarf Merging: HI Gas, Star Formation and Numerical Simulations
Hong-Xin Zhang, Rory Smith, Se-Heon Oh +12
A clear link between a dwarf-dwarf merger event and enhanced star formation (SF) in the recent past was recently identified in the gas-dominated merger remnant VCC 848, offering by…
Evidence of runaway gas cooling in the absence of supermassive black hole feedback at the epoch of cluster formation
J. Hlavacek-Larrondo, C. L. Rhea, T. Webb +17
Cosmological simulations, as well as mounting evidence from observations, have shown that supermassive black holes play a fundamental role in regulating the formation of stars thro…
Delayed Photons from Binary Evolution Help Reionize the Universe
Amy Secunda, Renyue Cen, Taysun Kimm +2
High-resolution numerical simulations including feedback and aimed at calculating the escape fraction (fesc) of hydrogen-ionizing photons often assume stellar radiation based on si…
Starbursting Nuclei in Old Dwarf Galaxies
Sanjaya Paudel, Suk-Jin Yoon
Nuclei of early-type dwarf galaxies (dEs) are usually younger than the galaxy main body, and such discrepancy in age has been a puzzle. To explore the origin of young nuclei in dEs…
