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…
RAMSES-MCR: A consistent multi-group treatment of cosmic rays physics in momentum-space with the RAMSES code
Nimatou-Seydi Diallo, Yohan Dubois, Alexandre Marcowith +2
Cosmic rays (CRs) are known to play a key role in many astrophysical environments: they can modify shock dynamics, influence the thermochemistry and the ionization of the interstel…
MEGATRON: Disentangling Physical Processes and Observational Bias in the Multi-Phase ISM of High-Redshift Galaxies
Nicholas Choustikov, Harley Katz, Alex J. Cameron +10
Now detected out to redshifts of , the rest-frame ultraviolet and optical spectra of galaxies encode numerous physical properties of the interstellar medium (ISM). Accu…
H-alpha as a Tracer of Star Formation in the SPHINX Cosmological Simulations
I. G. Kramarenko, J. Rosdahl, J. Blaizot +3
The H-alpha (Ha) emission line in galaxies is a powerful tracer of their recent star formation activity. With the advent of JWST, we are now able to routinely observe Ha in galaxie…
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…
The Pandora project. II: how non-thermal physics drives bursty star formation and temperate mass-loaded outflows in dwarf galaxies
Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt +11
Dwarf galaxies provide powerful laboratories for studying galaxy formation physics. Their early assembly, shallow gravitational potentials, and bursty, clustered star formation his…
