SDSS-V LVM: Resolving Physical Conditions in the Trifid Nebula

Natascha Sattler, J. Eduardo Méndez-Delgado, Kathryn Kreckel +18

The chemical abundance of the interstellar medium sets the initial conditions for star formation and provides a probe of chemical galaxy evolution models. However, unresolved inhom…

The galactic chemical evolution of carbon: Implications for stellar nucleosynthesis

Daniel A. Boyea, James W. Johnson, David H. Weinberg

Carbon (C) is thought to be produced by both core collapse supernovae (CCSN) and asymptotic giant branch (AGB) stars, but the relative contributions of these two sources are uncert…

SDSS-V LVM: Detectability of Wolf-Rayet stars and their He II ionizing flux in low-metallicity environments I. The weak-lined, early-type WN3 stars in the SMC

G. González-Torà, A. A. C. Sander, E. Egorova +18

The Small Magellanic Cloud (SMC) is the nearest low-metallicity dwarf galaxy. Its proximity and low reddening has enabled us to detect its Wolf-Rayet (WR) star population with 12 k…

Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts

Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54

The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…

Rise of the forsaken relics: connecting present-day stellar streams and phase-mixed galaxies to the Epoch of Reionization

Aritra Kundu, Robyn Sanderson, Adam Lidz +6

The `near-far' approach to studying reionization leverages the star formation histories of the Milky Way (MW) or Local Group (LG) galaxies, derived from resolved photometry, to inf…

Ultra-Faint Milky Way Satellites Discovered in Carina, Phoenix, and Telescopium with DELVE Data Release 3

C. Y. Tan, W. Cerny, A. B. Pace +76

We report the discovery of three Milky Way satellite candidates: Carina IV, Phoenix III, and DELVE 7, in the third data release of the DECam Local Volume Exploration survey (DELVE)…
