SDSS-V Local Volume Mapper (LVM): Dithered Data Cube Reconstruction with 3dcubegen
H. J. Ibarra-Medel, A. Z. Lugo-Aranda, R. de J. Zermeño +16
The Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) is conducting an unprecedented wide-field integral field spectroscopic survey of the Milky Way, the Magellanic Clo…
There is no single density: star-forming regions and galaxies hold more dense ionized gas than long assumed
J. Eduardo Méndez-Delgado, Christophe Morisset, William J. Henney +29
Ionized gas fills star-forming regions and galaxies, and nearly everything we know about its temperature, pressure, mass, and composition is inferred from its emission lines [1-3].…
Exploring the synergies of with MUSE spectroscopy in PHANGS H II regions
Eric Habjan, Kathryn Kreckel, Christopher Faesi +16
Spatially resolved maps of gas-phase metallicity provide key constraints on the chemical enrichment and mixing processes that drive galaxy evolution, but measurements based only on…
Toward Unbiased Abundance Measurements in Inhomogeneous Regions
Eric Habjan, Christopher Faesi, Kathryn Kreckel +10
Probing the chemical content of the interstellar medium (ISM) in nearby galaxies provides key insight into their chemical evolution and informs our interpretation of galaxies at hi…
SDSS-V LVM: Revealing the Physical and Chemical Structure of the Helix Nebula
R. Orozco-Duarte, J. E. Méndez-Delgado, J. A. Toalá +27
We present the first spatially contiguous study of the physical and chemical structure of the Helix Nebula (NGC~7293, PNG 036.1-57.1) based on integral-field spectroscopy from the…
The DESIRED strong-line calibrations: I. New empirical metallicity relations for the local and high-redshift universe
F. F. Rosales-Ortega, J. E. Méndez-Delgado, J. U. Guerrero-González +16
We present the most comprehensive set of empirical optical strong-line metallicity calibrations to date, based on the DEep Spectra of Ionised REgions Database (DESIRED), the larges…
