On the Effects of Local Environment on Active Galactic Nucleus (AGN) in the Horizon Run 5 Simulation
Ankit Singh, Changbom Park, Ena Choi +6
We use the Horizon Run 5 cosmological simulation to study the effect of galaxy intrinsic properties and the local environment on AGNs characterized by their threshold of the accret…
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…
Nonreciprocal Infrared Absorption via Resonant Magneto-optical Coupling to InAs
Komron Shayegan, Bo Zhao, Yonghwi Kim +2
Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity bec…
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 Dust-to-Gas Ratio and the Role of Radiation Pressure in Luminous, Obscured Quasars
Hyunsung D. Jun, Roberto J. Assef, Christopher M. Carroll +5
The absence of high Eddington ratio, obscured Active Galactic Nuclei (AGN) in local () samples of moderate luminosity AGN has generally been explained to result from…
Nanoscale axial position and orientation measurement of hexagonal boron nitride quantum emitters using a tunable nanophotonic environment
Pankaj K. Jha, Hamidreza Akbari, Yonghwi Kim +2
Color centers in hexagonal boron nitride (hBN) have emerged as promising candidates for single-photon emitters (SPEs) due to their bright emission characteristics at room temperatu…
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…
Wiggle Instability of Galactic Spiral Shocks: Effects of Magnetic Fields
Yonghwi Kim, Woong-Tae Kim, Bruce G. Elmegreen
It has been suggested that the wiggle instability (WI) of spiral shocks in a galactic disk is responsible for the formation of gaseous feathers observed in grand-design spiral gala…
Nature of the Wiggle Instability of Galactic Spiral Shocks
Woong-Tae Kim, Yonghwi Kim, Jeong-Gyu Kim
Gas in disk galaxies interacts nonlinearly with an underlying stellar spiral potential to form galactic spiral shocks. While numerical simulations typically show that spiral shocks…
Gaseous Spiral Structure and Mass Drift in Spiral Galaxies
Yonghwi Kim, Woong-Tae Kim
We use hydrodynamic simulations to investigate nonlinear gas responses to an imposed stellar spiral potential in disk galaxies. The gaseous medium is assumed to be infinitesimally…
Gaseous Structures in Barred Galaxies: Effects of the Bar Strength
Woong-Tae Kim, Woo-Young Seo, Yonghwi Kim
Using hydrodynamic simulations, we investigate the physical properties of gaseous substructures in barred galaxies and their relationships with the bar strength. The gaseous medium…
