The diverse nature of spiral arms in the Auriga Superstars cosmological hydrodynamic simulations
Robert J J Grand, Francesca Fragkoudi, Rüdiger Pakmor +4
The dynamical nature and formation mechanism(s) of galactic spiral arms remain long-standing problems in astrophysics. Most theoretical work is based on analytic calculations or id…
The collision and merger products of stars do not look alike: A magnetohydrodynamics comparison
Pavan Vynatheya, Taeho Ryu, Chen Wang +2
A significant fraction of stars experience close interactions, including collisions resulting from gravitational encounters and mergers within close binary systems. These processes…
Probing the Diversity of Type Ia Supernova Remnants in 3-D Hydrodynamic Simulations with X-ray Spectral Synthesis
Yusei Fujimaru, Shiu-Hang Lee, Gilles Ferrand +7
Type Ia supernovae (SNe), thermonuclear explosions of white dwarfs in binary systems, are widely used as standard candles owing to the empirical width-luminosity relation of their…
Formation of protostars and the launching of stellar core outflows with moving-mesh radiation non-ideal magnetohydrodynamics
Alexander C. Mayer, Rüdiger Pakmor, Thorsten Naab +5
We present an implementation of radiative transfer with flux-limited diffusion (FLD) for the moving-mesh code {\small AREPO} and use the method in a physical model for the formatio…
Environment matters: stronger magnetic fields in satellite galaxies
Maria Werhahn, Rüdiger Pakmor, Rebekka Bieri +3
Magnetic fields are ubiquitous in the universe and an important component of the interstellar medium. It is crucial to accurately model and understand their properties in different…
FEASTS Compared with Simulations: Abnormally Irregular and Extended HI Morphologies at a Column Density of in TNG50 and Auriga
Xuchen Lin, Jing Wang, Guinevere Kauffmann +2
With new atomic-hydrogen (HI) observations of FAST Extended Atlas of Selected Targets Survey (FEASTS), we present the first statistical comparison of HI morphology between observat…
