The atomic-to-molecular hydrogen transition in the TNG50 simulation: Using realistic UV fields to create spatially resolved HI maps
Andrea Gebek, Maarten Baes, Benedikt Diemer +6
Cold gas in galaxies provides a crucial test to evaluate the realism of cosmological hydrodynamical simulations. To extract the atomic and molecular hydrogen properties of the simu…
UV to submillimetre luminosity functions of TNG50 galaxies
Ana Trcka, Maarten Baes, Peter Camps +7
We apply the radiative transfer (RT) code SKIRT on a sample of ~14000 low-redshift (z<= 0.1) galaxies extracted from the TNG50 simulation to enable an apples-to-apples comparison w…
Monte Carlo radiative transfer with explicit absorption to simulate absorption, scattering, and stimulated emission
Maarten Baes, Peter Camps, Kosei Matsumoto
Context: The Monte Carlo method is probably the most widely used approach to solve the radiative transfer problem, especially in a general 3D geometry. The physical processes of em…
The high redshift SFR-M* relation is sensitive to the employed star formation rate and stellar mass indicators: Towards addressing the tension between observations and simulations
A. Katsianis, V Gonzalez, D. Barrientos +9
There is a severe tension between the observed star formation rate (SFR) - stellar mass () relations reported by different authors at . In addition, the o…
The Herschel Exploitation of Local Galaxy Andromeda (HELGA) VII: A SKIRT radiative transfer model and insights on dust heating
S. Viaene, M. Baes, A. Tamm +17
The radiation of stars heats dust grains in the diffuse interstellar medium and in star-forming regions in galaxies. Modelling this interaction provides information on dust in gala…
Radiative transfer in disc galaxies V. The accuracy of the KB approximation
Dukhang Lee, Maarten Baes, Kwang-Il Seon +3
We investigate the accuracy of an approximate radiative transfer technique that was first proposed by Kylafis & Bahcall (hereafter the KB approximation) and has been popular in mod…
