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…
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…
