Magnetic field generation in mergers of massive main-sequence stars

Sebastian T. Ohlmann, Fabian R. N. Schneider, Friedrich K. Roepke +3

Magnetic fields are found in many astrophysical objects, ranging from galaxy clusters to the interstellar medium of galaxies and neutron stars. Strong surface magnetic fields are a…

Trading oxygen for iron II. Oxygen- versus iron-dependent cosmic star formation history

Martyna Chruślińska, Mirko Curti, Ruediger Pakmor +4

Due to their different nucleosynthetic origin, a stellar population produces oxygen (O) and iron (Fe) on different timescales and their relative abundance can deviate strongly from…

CRexit: how different cosmic ray transport modes affect thermal instability in the circumgalactic medium

Matthias Weber, Timon Thomas, Christoph Pfrommer +1

The circumgalactic medium (CGM) plays a critical role in galaxy evolution, influencing gas flows, feedback processes, and galactic dynamics. Observations show a substantial cold ga…

The Lumina Project: CMB Optical Depth Fluctuations from Patchy Reionization

Aaron Smith, Oliver Zier, Rahul Kannan +8

Patchy reionization couples the ionized-bubble morphology to the underlying density field, making the CMB Thomson optical depth sensitive to both the global ionization history and…

Coupling between stellar and HI lopsidedness in Milky Way-type galaxies from the Auriga Superstars cosmological simulations

Arianna Dolfi, Facundo A. Gómez, Rebekka Bieri +5

Lopsidedness is common in disk galaxies, yet its origin and evolution remain unclear. Previous studies typically examined stellar and gas asymmetries separately, but a combined ana…

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…
