The effect of baryons on the positions and velocities of satellite galaxies in the MTNG simulation
Sergio Contreras, Raul E. Angulo, Sownak Bose +5
Mock galaxy catalogues are often constructed from dark-matter-only simulations based on the galaxy-halo connection. Although modern mocks can reproduce galaxy clustering to some ex…
Synthetic JWST galaxy images in the TNG50 simulation - I. Model validation and comparison to observations
Alejandro Guzmán-Ortega, Gustavo Bruzual, Vicente Rodriguez-Gomez +1
We use the TNG50 cosmological simulation and three-dimensional radiative transfer post-processing to generate dust-aware synthetic observations of galaxies at a…
Star Formation Rates, Metallicities, and Stellar Masses on kpc-scales in TNG50
Jia Qi, Alex M. Garcia, Davis Robinson +7
Integral field units (IFU) have extended our knowledge of galactic properties to kpc (or, sometimes, even smaller) patches of galaxies. These scales are where the physics driving g…
Photometric analysis of the intracluster light in the TNG300 simulation and wide-field observations
Daniel Montenegro-Taborda, Vicente Rodriguez-Gomez, Vladimir Avila-Reese +5
We present a robust, apples-to-apples comparison between the photometric properties of the intracluster light (ICL) in the TNG300 magnetohydrodynamic cosmological simulation and th…
Ray-tracing vs. Born approximation in full-sky weak lensing simulations of the MillenniumTNG project
Fulvio Ferlito, Christopher T. Davies, Volker Springel +7
Weak gravitational lensing is a powerful tool for precision tests of cosmology. As the expected deflection angles are small, predictions based on non-linear N-body simulations are…
Does the Fundamental Metallicity Relation Evolve with Redshift? II: The Evolution in Normalisation of the Mass-Metallicity Relation
Alex M. Garcia, Paul Torrey, Sara L. Ellison +10
The metal content of galaxies is a direct probe of the baryon cycle. A hallmark example is the relationship between a galaxy's stellar mass, star formation rate (SFR), and gas-phas…
