SIMBA-C: An updated chemical enrichment model for galactic chemical evolution in the SIMBA simulation

Renier T. Hough, Douglas Rennehan, Chiaki Kobayashi +4

We introduce a new chemical enrichment and stellar feedback model into GIZMO, using the SIMBA sub-grid models as a base. Based on the state-of-the-art chemical evolution model of K…

Rapid Chemical Enrichment by Intermittent Star Formation in GN-z11

Chiaki Kobayashi, Andrea Ferrara

We interpret the peculiar super-solar nitrogen abundance recently reported by the James Webb Space Telescope observations for GN-z11 () using our state-of-the-art chemical…

Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)

Roberta Paladini, Catherine Zucker, Robert Benjamin +67

A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…

The impact of supernova feedback on the mass-metallicity relations

Dyna Ibrahim, Chiaki Kobayashi

Metallicity is a fundamental physical property that strongly constrains galaxy formation and evolution. The formation of stars in galaxies is suppressed by the energy released from…

The Andromeda Galaxy's Last Major Merger: Constraints from the survey of Planetary Nebulae

Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +7

The Andromeda galaxy (M 31) has experienced a tumultuous merger history as evidenced by the many substructures present in its inner halo. We use planetary nebulae (PNe) as chemodyn…

Inhomogeneous enrichment of radioactive nuclei in the Galaxy: Deposition of live Mn-53, Fe-60, Hf-182, and Pu-244 into deep-sea archives. Surfing the wave?

Benjamin Wehmeyer, Andrés Yagüe López, Benoit Côté +3

While modelling the galactic chemical evolution (GCE) of stable elements provides insights to the formation history of the Galaxy and the relative contributions of nucleosynthesis…
