Multiple Beads-on-a-string: Dark Matter-Deficient Galaxy Formation in a Mini-bullet Satellite-satellite Galaxy Collision
Joohyun Lee, Eun-jin Shin, Ji-hoon Kim +2
Dark matter-deficient galaxies (DMDGs) discovered in the survey of ultra-diffuse galaxies (UDGs), in apparent conflict with standard CDM, may be produced by high-velocity galaxy-ga…
Merger Tree-based Galaxy Matching: A Comparative Study Across Different Resolutions
Minyong Jung, Ji-hoon Kim, Boon Kiat Oh +3
We introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their su…
Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars
Dohyeong Kim, Myungshin Im, Minjin Kim +4
We present bolometric luminosity () and black hole (BH) mass () estimators based on mid-infrared (MIR) continuum luminosity (hereafter, ) that…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Discovers an Overdensity around a Metal Absorption-selected Galaxy at
Yunjing Wu, Feige Wang, Zheng Cai +27
The launch of opens a new window for studying the connection between metal-line absorbers and galaxies at the end of the Epoch of Reionization (EoR). Previous studies…
A large population of strongly lensed faint submillimetre galaxies in future dark energy surveys inferred from JWST imaging
James Pearson, Stephen Serjeant, Wei-Hao Wang +13
Bright galaxies at sub-millimetre wavelengths from Herschel are now well known to be predominantly strongly gravitationally lensed. The same models that successfully predicted this…
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…
