Early onset of the hot circumgalactic medium around Milky Way galaxies

Víctor Rufo-Pastor, Oscar Agertz, Santi Roca-Fábrega +6

Hot coronae are key regulators in Milky Way (MW)-type galaxy formation and are thought to emerge once a galaxy's dark matter halo crosses a critical mass threshold, $M_{\mathrm{vir…

The driving mode of turbulence in disc galaxy simulations with adaptive mesh refinement

James Watt, Christoph Federrath, Thorsten Tepper-Garcia +2

Turbulence is a key ingredient in controlling the structure of the interstellar medium (ISM) and star formation, yet we still lack a detailed understanding of its drivers in galaxi…

Nexus-CDM: Isolated Galaxy Simulations with Cosmologically Evolving Dark-Matter Halos I. Method and Validation

Thor Tepper-García, Joss Bland-Hawthorn, Oscar Agertz +1

Galaxy evolution can be modelled in two complementary ways. Standalone simulations place a single galaxy in isolation, evolving it under controlled initial conditions without the s…

Turbulent gas-rich discs at high redshift: the origin of early massive stellar bars

Joss Bland-Hawthorn, Thor Tepper-Garcia, Chris Hamilton +4

Recent observations combining the power of ALMA and JWST have revealed large ( kpc), massive () stellar bars at when the Universe…

Magnetic destabilisation in disc galaxies: Filament/feather formation

Raghav Arora, Oscar Agertz, Christoph Federrath +1

Gas gravitational instability plays a crucial role in secular galactic evolution, but the role played by magnetic fields in mediating this instability - despite their dynamical rel…

The AGORA High-resolution Galaxy Simulations Comparison Project. IX - Part 2: Effects of a Major Galaxy Merger on the Stellar Morphology of a Milky Way-mass Galaxy Progenitor

Thinh Huu Nguyen, Kirk S. S. Barrow, Minyong Jung +23

Galaxy mergers, with their high sensitivity to initial conditions, provide a valuable setting for comparative studies of galaxy simulation codes. Following our first paper focusing…
