The N/O-O/H relation across large-scale environments
Yllari K. González-Koda, Almudena Zurita, Laura Sánchez-Menguiano +7
The large-scale structure (LSS) of the Universe shapes galaxy evolution through its intricate web-like morphology, yet its specific influence on gas-phase chemical abundances remai…
The impact of bars on the properties of HII regions in the TIMER survey
Laura Sánchez-Menguiano, Dimitri A. Gadotti, Almudena Zurita +10
In this study we perform a comparative analysis of the properties of the HII regions located in different areas of barred galaxies, with the aim of investigating the impact of bars…
SIGNALS on the mixing of oxygen and nitrogen in the spiral galaxy NGC 6946
Fabio Bresolin, David Fernández-Arenas, Laurie Rousseau-Nepton +10
As part of the SIGNALS survey, which comprises a sample of approximately 40 nearby galaxies observed with the Fourier transform spectrometer SITELLE, we present a study of metal mi…
CAVITY: Calar Alto Void Integral-field Treasury surveY. I. First public data release
Rubén García-Benito, Andoni Jiménez, Laura Sánchez-Menguiano +40
The Calar Alto Void Integral-field Treasury surveY (CAVITY) is a legacy project aimed at characterising the population of galaxies inhabiting voids, which are the most under-dense…
Impacts of bar-driven shear and shocks on star formation
Taehyun Kim, Dimitri A. Gadotti, Miguel Querejeta +12
Bars drive gas inflow. As the gas flows inwards, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation and change the gas properties.…
The CAVITY project. The spatially resolved stellar population properties of galaxies in voids
Ana M. Conrado, Rosa M. González Delgado, Rubén García-Benito +28
The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large volumes in between named voids. Galaxies in voids have been found to be of…
Stellar mass-metallicity relation throughout the large-scale structure of the Universe: CAVITY mother sample
Jesús Domínguez-Gómez, Isabel Pérez, Tomás Ruiz-Lara +21
Void galaxies are essential for understanding the physical processes that drive galaxy evolution because they are less affected by external factors than galaxies in denser environm…
The softness diagram for MaNGA star-forming regions: diffuse ionized gas contamination or local HOLMES predominance?
Enrique Pérez-Montero, Igor Zinchenko, José M. Vílchez +3
We explore the so-called softness diagram -- whose main function is to provide the hardness of the ionizing radiation in star-forming regions -- in order to check whether hot and o…
Bar effect on gas-phase abundance gradients. II. Luminosity-dependent flattening
A. Zurita, E. Florido, F. Bresolin +2
We present here the second part of a project that aims at solving the controversy on the issue of the bar effect on the radial distribution of metals in the gas-phase of spiral gal…
Bar effect on gas-phase abundance gradients. I. Data sample and chemical abundances
A. Zurita, E. Florido, F. Bresolin +2
Studies of gas-phase radial metallicity profiles in spirals published in the last decade have diminished the importance of galactic bars as agents that mix and flatten the profiles…
Observational constraints to boxy/peanut bulge formation time
I. Perez, I. Martinez-Valpuesta, T. Ruiz-Lara +10
Boxy/peanut bulges are considered to be part of the same stellar structure as bars and both could be linked through the buckling instability. The Milky Way is our closest example.…
Central enhancement of the nitrogen-to-oxygen abundance ratio in barred galaxies
E. Florido, A. Zurita, I. Perez +3
Bar-induced gas inflows towards the galaxy centres are recognized as a key agent for the secular evolution of galaxies. One immediate consequence is the accumulation of gas in the…
On the morphology of dust lanes in galactic bars
L. Sánchez-Menguiano, I. Pérez, A. Zurita +5
The aim of our study is to use dynamical simulations to explore the influence of two important dynamical bar parameters, bar strength and bar pattern speed, on the shape of the bar…
Ionised gas abundances in barred spiral galaxies
E. Florido, I. Pérez, A. Zurita +1
This is the third paper of a series devoted to study the properties of bars from long slit spectroscopy to understand their formation, evolution and their influence on the evolutio…
Multiwavelength study of the star formation in the bar of NGC 2903
G. Popping, I. Perez, A. Zurita
NGC 2903 is a nearby barred spiral with an active starburst in the center and Hii regions distributed along its bar. We aim to analyse the star formation properties in the bar regi…
Deriving the pattern speed using dynamical modelling of gas flows in barred galaxies
I. Perez, K. C. Freeman, R. Fux +1
In this paper we analyse the methodology to derive the bar pattern speed from dynamical simulations. The results are robust to the changes in the vertical-scale height and in the m…
The warm ionized medium in spiral galaxies
L. M. Haffner, R. -J. Dettmar, J. E. Beckman +6
This article reviews observations and models of the diffuse ionized gas that permeates the disk and halo of our Galaxy and others. It was inspired by a series of invited talks pres…
Study of the stellar line-strength indices and kinematics along bars
I. Perez, P. Sanchez-Blazquez, A. Zurita
This is the first paper of a series aimed to understand the formation and evolution of bars in early-type spirals and their influence in the evolution of the galaxy. Optical long-s…
