Nebular emission from composite star-forming galaxies -- I. A novel modelling approach
Christophe Morisset, Stéphane Charlot, Sebastián F. Sánchez +3
We introduce a novel approach to modelling the nebular emission from star-forming galaxies by combining the contributions from many HII regions incorporating loose trends in physic…
HII regions and diffuse ionized gas in the AMUSING++ Compilation: I. Catalogue presentation
A. Z. Lugo-Aranda, S. F. Sánchez, J. K. Barrera-Ballesteros +4
We present a catalog of 52,000 extragalactic HII regions and their spectroscopic properties obtained using Integral Field Spectroscopy (IFS) from MUSE observations. The sampl…
SDSS-IV MaNGA: pyPipe3D analysis release for 10,000 galaxies
S. F. Sánchez, J. K. Barrera-Ballesteros, E. Lacerda +12
We present here the analysis performed using the pyPipe3D pipeline for the final MaNGA dataset included in the SDSS seventeenth data-release. This dataset comprises more than 10,00…
SDSS-IV MaNGA: The radial distribution of physical properties within galaxies in the nearby universe
J. K. Barrera-Ballesteros, S. F. Sánchez, C. Espinosa-Ponce +10
Using the largest sample of galaxies observed with an optical integral field unit (IFU, the SDSS-IV MaNGA survey, 10000 targets), we derive the radial distribution of the phy…
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…
HII regions in CALIFA survey: II. The relation between their physical properties and galaxy evolution
C. Espinosa-Ponce, S. F. Sánchez, C. Morisset +5
We present in here the exploration of the physical properties of the sample of HII regions and aggregations of the last HII regions catalog of the CALIFA survey. This sample compri…
pyFIT3D and pyPipe3D -- The new version of the Integral Field Spectroscopy data analysis pipeline
Eduardo A. D. Lacerda, S. F. Sánchez, A. Mejía-Narváez +5
We present a new version of the FIT3D and Pipe3D codes, two packages to derive properties of the stellar populations and the ionized emission lines from optical spectroscopy and in…
An Empirical Calibration of the Helium Abundance in HII Regions based in Literature and CALIFA Survey data
M. Valerdi, J. K. Barrera-Ballesteros, S. F. Sánchez +3
Helium is the second most common chemical species in the Universe. The study of helium abundance has the potential to unravel the chemical evolution of and within galaxies. In this…
[/Fe] traced by H ii regions from the CALIFA survey: The connection between morphology and chemical abundance patterns
S. F. Sánchez, C. Espinosa-Ponce, L. Carigi +6
Differential enrichment between - and Fe-peak elements is known to be strongly connected with the shape of the star formation history (SFH), the star formation efficiency (SFE),…
From global to spatially resolved in low-redshift galaxies
S. F. Sanchez, C. J. Walcher, C. Lopez-Coba +4
Our understanding of the structure, composition and evolution of galaxies has strongly improved in the last decades, mostly due to new results based on large spectroscopic and imag…
HII regions in the CALIFA survey: I. Catalog presentation
C. Espinosa-Ponce, S. F. Sánchez, C. Morisset +5
We present a new catalog of HII regions based on the integral field spectroscopy (IFS) data of the extended CALIFA and PISCO samples. The selection of HII regions was based on two…
Galaxies hosting an AGN: a view from the CALIFA survey
Eduardo A. D. Lacerda, Sebastián F. Sánchez, R. Cid Fernandes +3
We study the presence of optically-selected Active Galactic Nuclei (AGNs) within a sample of 867 galaxies extracted from the extended {\it Calar-Alto Legacy Integral Field spectros…
