pyHIIextractor: A tool to detect and extract physical properties of HII regions from Integral Field Spectroscopic data
A. Z. Lugo-Aranda, S. F. Sánchez, C. Espinosa-Ponce +5
We present a new code named pyHIIextractor, which detects and extracts the main features (positions and radii) of clumpy ionized regions, i.e. candidate HII regions, using Hα emiss…
Evidence for the Accretion of Gas in Star-Forming Galaxies: High N/O Abundances in Regions of Anomalously-Low Metallicity
Yuanze Luo, Timothy Heckman, Hsiang-Chih Hwang +11
While all models for the evolution of galaxies require the accretion of gas to sustain their growth via on-going star formation, it has proven difficult to directly detect this inf…
Local and global gas metallicity versus stellar age relation in MaNGA galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +1
The search for new global scaling relations linking physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially resolved relations has be…
Arm-interarm gas abundance variations explored with MUSE: the role of spiral structure in the chemical enrichment of galaxies
Laura Sánchez-Menguiano, Sebastián F. Sánchez, Isabel Pérez +4
Spiral arms are the most characteristic features of disc galaxies, easily distinguishable due to their association with ongoing star formation. However, the role of spiral structur…
SIGNALS: I. Survey Description
L. Rousseau-Nepton, R. P. Martin, C. Robert +60
SIGNALS, the Star formation, Ionized Gas, and Nebular Abundances Legacy Survey, is a large observing program designed to investigate massive star formation and HII regions in a sam…
The fundamental metallicity relation emerges from the local anti-correlation between star formation rate and gas-phase metallicity existing in disk galaxies
J. Sanchez Almeida, L. Sanchez-Menguiano
The fundamental metallicity relation (FMR) states that galaxies of the same stellar mass but larger star formation rate (SFR) tend to have smaller gas-phase metallicity (<Zg>). It…
