An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind

The Astrophysical Journal
We present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram pressure stripping of a dwarf satellite galaxy near the pericenter of its

Quantifying Bursty Star Formation in Dwarf Galaxies

The Open Journal of Astrophysics
Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than ~100 Myr should lead to discontinuous

On the Evolutionary History of a Simulated Disk Galaxy as Seen by Phylogenetic Trees

The Astrophysical Journal
Phylogenetic methods have long been used in biology and more recently have been extended to other fields—for example, linguistics and technology—to study evolutionary histories.

Local variations of the radial metallicity gradient in a simulated NIHAO-UHD Milky Way analogue and their implications for (extra-)galactic studies

The Open Journal of Astrophysics
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 linearity, scatter, spatial coherence, and age-related variations of ...

A 13 Billion Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to z = 9 with JWST and Archival Surveys

The Astrophysical Journal Supplement Series
Galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and in the high-redshift Universe, as they trace the baryon cycle and growth of galaxies.
