mitigating the overcooling problem with sink-based bursty star formation in a high-z dwarf galaxy
Cheonsu Kang, Taysun Kimm, Daniel Han +4
Star formation is a fundamental driver of galaxy evolution, yet many galaxy formation models still fail to regulate it realistically, allowing gas to collapse too efficiently and o…
From short-lived to long-lived clouds: impact of star formation models on giant molecular cloud evolution in simulations of an NGC 300-like galaxy
Daniel Han, Taysun Kimm, Cheonsu Kang +3
Multi-wavelength observations of molecular and ionized gas indicate that GMCs are short-lived, generally dispersing within one or two dynamical timescales. To investigate the physi…
Uncertainties in high- galaxy properties inferred from SED fitting using JWST NIRCam photometry
Jiyoung Choe, Taysun Kimm, Harley Katz +4
Numerous high- galaxies have recently been observed with JWST, providing new insights into early galaxy evolution. Their physical properties are typically derived through spectr…
Impact of star formation models on the growth of simulated galaxies at high redshifts
Cheonsu Kang, Taysun Kimm, Daniel Han +4
Star formation is a key process that governs the baryon cycle within galaxies, however, the question of how it controls their growth remains elusive due to modeling uncertainties.…
