The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
Bojun Tao, Hong-Xin Zhang, Wenting Wang +8
Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information about galaxy merger hi…
How Mergers and Flybys Shape Azimuthal Age Patterns in Spiral Galaxies
Qian-Hui Chen, Alex M. Garcia, Zefeng Li +7
Spiral structures are one of the most common features in galaxies, yet their origins and evolution remain debated. Stellar age distributions offer crucial insights into galaxy evol…
Metallicity Gradients in Modern Cosmological Simulations I: Tension Between Smooth Stellar Feedback Models and Observations
Alex M. Garcia, Paul Torrey, Aniket Bhagwat +14
The metallicity of galaxies, and its variation with galactocentric radius, provides key insights into the formation histories of galaxies and the physical processes driving their e…
Local variations of the radial metallicity gradient in a simulated NIHAO-UHD Milky Way analogue and their implications for (extra-)galactic studies
Sven Buder, Tobias Buck, Qian-Hui Chen +1
Radial metallicity gradients are fundamental to understanding galaxy formation and evolution. In our high-resolution simulation of a NIHAO-UHD Milky Way analogue, we analyze the li…
The MAGPI Survey: the kinematic morphology-density relation (or lack thereof) and the Hubble sequence at
Caroline Foster, Mark W. Donoghoe, Andrew Battisti +26
This work presents visual morphological and dynamical classifications for 637 spatially resolved galaxies, most of which are at intermediate redshift (), in the Middle-Ag…
