The SDSS-V Local Volume Mapper (LVM): Data Analysis Pipeline
Sebastian F. Sanchez, Alfredo Mejía-Narvaez, Oleg V. Egorov +10
We introduce the Data Analysis Pipeline (DAP) for the Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM) project, referred to as the LVM-DAP. We outline our methods for…
Analyzing the Abundance Discrepancy Problem in HII Regions with Photoionization Modeling
Ahmad Nemer, J. E. Mendez-Delgado, Natascha Sattler +5
Understanding the complex ionization structure and chemical composition of \hii\ regions poses a significant challenge in astrophysics. The abundance discrepancy problem, character…
The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich
James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12
Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
Machine learning the gap between real and simulated nebulae: A domain-adaptation approach to classify ionised nebulae in nearby galaxies
Francesco Belfiore, Michele Ginolfi, Guillermo Blanc +8
Classifying ionised nebulae in nearby galaxies is crucial to studying stellar feedback mechanisms and understanding the physical conditions of the interstellar medium. This classif…
Metallicity calibrations based on auroral lines from PHANGS-MUSE data
Matilde Brazzini, Francesco Belfiore, Michele Ginolfi +13
We present a chemical analysis of selected HII regions from the PHANGS-MUSE nebular catalogue. Our intent is to empirically re-calibrate strong-line diagnostics of gas-phase metall…
Discovery of 2200 new supernova remnants in 19 nearby star-forming galaxies with MUSE spectroscopy
Jing Li, K. Kreckel, S. Sarbadhicary +18
We present the largest extragalactic survey of supernova remnant (SNR) candidates in nearby star-forming galaxies using exquisite spectroscopic maps from MUSE. Supernova remnants e…
