CAVITY: Calar Alto Void Integral-field Treasury surveY: II. Second public data release
B. Bidaran, A. Jiménez, R. García-Benito +30
Studying galaxy evolution under the unique environmental conditions of cosmic voids provides an opportunity to disentangle the role of the large-scale environment in shaping mass a…
Stellar mass is not the best predictor of galaxy metallicity. The gravitational potential-metallicity relation
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Sebastián F. Sánchez +1
Interpreting the scaling relations followed by galaxies is a fundamental tool for assessing how well we understand galaxy formation and evolution. Several scaling relations involvi…
Galaxies in voids assemble their stars slowly
J. Domínguez-Gómez, I. Pérez, T. Ruiz-Lara +20
Galaxies in the Universe are distributed in a web-like structure characterised by different large-scale environments: dense clusters, elongated filaments, sheetlike walls, and unde…
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…
Characterizing the local relation between star formation rate and gas-phase metallicity in MaNGA spiral galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +4
The role of gas accretion in galaxy evolution is still a matter of debate. The presence of inflows of metal-poor gas that trigger star formation bursts of low metallicity has been…
Morpho-kinematic properties of field S0 bulges in the CALIFA survey
J. Mendez-Abreu, J. A. L. Aguerri, J. Falcon-Barroso +22
We study a sample of 28 S0 galaxies extracted from the integral-field spectroscopic (IFS) survey CALIFA. We combine an accurate two-dimensional (2D) multi-component photometric dec…
The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +6
We characterise the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial resolution of the dat…
Star formation in the local Universe from the CALIFA sample. II. Activation and quenching mechanisms in bulges, bars, and disks
C. Catalán-Torrecilla, A. Gil de Paz, A. Castillo-Morales +22
We estimate the current extinction-corrected H star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multi-…
Arm and interarm abundance gradients in CALIFA spiral galaxies
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +23
Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with easily distinguishable c…
Observational hints for radial migration in disc galaxies from CALIFA
T. Ruiz-Lara, I. Pérez, E. Florido +22
Context: According to numerical simulations, stars are not always kept at their birth galactocentric distances but migrate. The importance of this radial migration in shaping galac…
The Mass-Metallicity Relation revisited with CALIFA
S. F. Sánchez, J. K. Barrera-Ballesteros, L. Sánchez-Menguiano +14
We present an updated version of the mass--metallicity relation (MZR) using integral field spectroscopy data obtained from 734 galaxies observed by the CALIFA survey. These unparal…
