The COLIBRE-SKIRT pipeline: Calibration-free dust radiative transfer postprocessing for cosmological simulations

Andrea Gebek, Maarten Baes, Nick Andreadis +16

The paper introduces the COLIBRE‑SKIRT pipeline, a calibration‑free method that uses the SKIRT radiative transfer code to generate multi‑wavelength mock observations from large‑vol…

Galaxy luminosity functions from far-UV to submillimetre at in the COLIBRE simulations

Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +15

We present predictions from the recent COLIBRE cosmological hydrodynamical simulations of galaxy formation for the present-day galaxy luminosity functions (LFs) at wavelengths rang…

The multi-wavelength Tully-Fisher relation in the TNG50 cosmological simulation

Maarten Baes, Andrea Gebek, Sabelo Kunene +8

The Tully-Fisher relation (TFR) is one of the most important and widely used empirical correlations in extragalactic astronomy. Apart from its importance as a secondary distance in…

The galaxy ultraviolet luminosity function from to in the COLIBRE simulations

Shengdong Lu, Carlos S. Frenk, Cedric G. Lacey +17

JWST has enabled the detection of galaxies in the earliest stages of cosmic history. We compare the ultraviolet luminosity functions (UVLFs) at redshifts predicted by the…

TODDLERS: A New UV to Millimeter Emission Library for Star-Forming Regions. II. Star Formation Rate Indicators Using Auriga Zoom Simulations

Anand Utsav Kapoor, Maarten Baes, Arjen van der Wel +6

Current galaxy formation simulations often approximate star-formation, necessitating models of star-forming regions to produce observables. In the first paper of the series, we int…

The TNG50-SKIRT Atlas: post-processing methodology and first data release

Maarten Baes, Andrea Gebek, Ana Trcka +17

Galaxy morphology is a powerful diagnostic to assess the realism of cosmological hydrodynamical simulations. Determining the morphology of simulated galaxies requires the generatio…

The TNG50-SKIRT Atlas: wavelength dependence of the effective radius

Maarten Baes, Aleksandr Mosenkov, Raymond Kelly +17

Galaxy sizes correlate with many other important properties of galaxies, and the cosmic evolution of galaxy sizes is an important observational diagnostic for constraining galaxy e…

Cosmological simulations of the high-redshift galaxy population adopting a variable stellar initial mass function

Anna Durrant, Robert A. Crain, Cedric G. Lacey +15

JWST surveys reveal a greater space density of high-redshift UV-bright galaxies than predicted by conventional galaxy formation models. We present results from a cMpc cosmo…

The TNG50-SKIRT Atlas: Spatially resolved synthetic galaxies from the ultraviolet to the submillimetre (DR2)

Maarten Baes, Paul Vauterin, Abdurro'uf +20

We present the second data release (DR2) of the TNG50-SKIRT Atlas (TSA), a library of synthetic, spatially resolved galaxy observables. The atlas is constructed by post-processing…

The evolution of galaxy dust scaling relations in the COLIBRE simulations

Aswin P. Vijayan, James W. Trayford, Joop Schaye +11

The paper uses the COLIBRE cosmological simulations to study how dust mass, composition, and grain sizes in galaxies evolve from the early Universe to the present, comparing predic…
