Towards robust simulations of the galactic dynamo: a cross-code comparison between Eulerian and Lagrangian schemes

Mark Ivan Ugalino, Benedikt Diemer, Vadim A. Semenov +8

Galactic magnetic fields are thought to be seeded by microscopic processes such as the Biermann battery and are primarily amplified to observed microgauss strengths by dynamo proce…

The VariableTNG project: mass-dependent regulation of galaxy morphology by baryonic feedback

Yikai Liu, Hong Guo, Volker Springel +3

Galaxy morphology is shaped by both assembly history and baryonic processes, but their relative roles remain uncertain. We use the VariableTNG (VTNG) simulation suite to investigat…

The VariableTNG project: how baryonic mechanisms shape galaxy properties

Kexin Liu, Hong Guo, Luis C. Ho +3

We use 50 Sobol-sampled VariableTNG simulations, varying eight subgrid parameters at fixed cosmology and initial conditions, to determine which baryonic processes regulate galaxies…

Evaluating the flexibility of the MillenniumTNG galaxy formation model with multi-zoom re-simulations

Francisco Maion, Raul E. Angulo, Volker Springel +2

In this study we introduce a new simulation campaign designed to understand how parameters that control star-formation and AGN feedback processes in cosmological hydrodynamical sim…

The PICO-Cluster Project: presenting the galaxy cluster sample and studying magnetic field growth, Faraday rotation and Braginskii heating

Thomas Berlok, Christoph Pfrommer, Ewald Puchwein +9

Galaxy clusters constitute a microcosm of the Universe and offer a unique laboratory for studying plasma astrophysics, encompassing processes such as cosmic-ray acceleration and no…

X-ray emission maps and scaling relations in IllustrisTNG and MillenniumTNG: Differences between cluster and group regimes

Franklin Aldás, Facundo A. Gómez, Volker Springel +3

X-ray observations are a primary probe of the intracluster medium, widely used to infer galaxy cluster masses and scaling relations. We present and validate a pipeline to generate…

Learning the Universe with PRFM-vol: Introducing a new subgrid model for star formation in cosmological simulations

Jan D. Burger, Volker Springel, Eve C. Ostriker +7

We introduce PRFM-vol, a new subgrid model for star formation in cosmological simulations that aims to increase the physical realism of cosmological simulations by leveraging resul…

The evolution of the baryonic content and mass profiles of satellite galaxies in the MTNG simulations

Sergio Contreras, Raul E. Angulo, Giovanni Aricò +5

Empirical models often rely on key relations from the galaxy--halo connection to construct mock galaxy catalogues. These relations typically describe central galaxies more accurate…

Revisiting radio synchrotron diagnostics in star-forming galaxies

Maria Werhahn, Christoph Pfrommer, Philipp Girichidis +7

Radio continuum observations are widely used to study cosmic ray (CR) electron populations and transport processes in star-forming galaxies, but their interpretation relies on seve…
