The metallicity of a supernova progenitor, together with its mass, is one of the main parameters that can rule their outcome. We present the second study of nearby supernova (SN) host galaxies (0.005texto impreso
We study the stellar properties of 44 face-on spiral galaxies from the Calar Alto Legacy Integral Field Area survey via full spectrum fitting techniques. We compare the age profiles with the surface brightness distribution in order to highlight [...]texto impreso
Marino, Raffaella Anna ; Gil de Paz, Armando ; Cardiel López, Nicolás ; Castillo Morales, África ; Catalán Torrecilla, Cristina ; ..., otros. | EDP Sciencies | 2016-01We study, for the first time in a statistically significant and well-defined sample, the relation between the outer-disk ionized-gas metallicity gradients and the presence of breaks in the surface brightness profiles of disk galaxies. Sloan Digi[...]texto impreso
Photoionization models of HIT regions require as input a description of the ionizing spectral energy distribution (SED) and of the gas distribution, in terms of ionization parameter U and chemical abundances (e.g., O/H and N/O). A strong degener[...]texto impreso
Marino, Raffaella Anna ; Gil de Paz, Armando ; otros, ... | UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA | 2016-04We present an improved version of FIT3D, a fitting tool for the analysis of the spectroscopic properties of the stellar populations and the ionized gas derived from moderate resolution spectra of galaxies. This tool was developed to analyze inte[...]texto impreso
Marino, Raffaella Anna ; Gil de Paz, Armando | Universidad Nacional Autónoma Mexico, Inst. de Astronomía | 2016-04We present PIPE3D, an analysis pipeline based on the FIT3D fitting tool, developed to explore the properties of the stellar populations and ionized gas of integral field spectroscopy (IFS) data. PIPE3D was created to provide coherent, simple to [...]texto impreso

We carry out a detailed 2-D study of the ionised gas in the local universe galaxy UGC 9837. In nearby galaxies, like the galaxy in question here, the spatial distribution of the physical properties can be studied in detail, providing be[...]texto impreso
The "main sequence of galaxies"—defined in terms of the total star formation rate ? versus the total stellar mass M *—is a well-studied tight relation that has been observed at several wavelengths and at different redshifts. All earlier studies [...]texto impreso
Integral field spectroscopy (IFS) studies based on CALIFA survey data have recently revealed ongoing low-level star formation (SF) in the periphery of a small fraction (~10%) of local early-type galaxies (ETGs), witnessing a still ongoing inside[...]texto impreso
Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24texto impreso
Catalán Torrecilla, Cristina ; Gil de Paz, Armando ; Castillo Morales, África ; Pérez González, Pablo Guillermo ; Marino, Raffaella Anna ; otros, ... | EDP Sciencies | 2015-12Context. The star formation rate (SFR) is one of the main parameters used to analyze the evolution of galaxies through time. The need for recovering the light reprocessed by dust commonly requires the use of low spatial resolution far-infrared d[...]texto impreso
We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies displaying a wide range of morphologies across the Hubble sequence, from ellipticals to la[...]texto impreso

J. ; Wisotzki, L. | EDP Sciencies | 2014-10While studies of gasphase metallicity gradients in disc galaxies are common, very little has been done towards the acquisition of stellar abundance gradients in the same regions. We present here a comparative study of the stellar metallicity and[...]texto impreso
While studies of gas-phase metallicity gradients in disc galaxies are common, very little has been done in the acquisition of stellar abundance gradients in the same regions. We present here a comparative study of the stellar metallicity and age[...]texto impreso
The velocity function (VF) is a fundamental observable statistic of the galaxy population that is similar to the luminosity function in importance, but much more difficult to measure. In this work we present the first directly measured circular [...]texto impreso
Various different physical processes contribute to the star formation and stellar mass assembly histories of galaxies. One important approach to understanding the significance of these different processes on galaxy evolution is the study of the [...]texto impreso

Jakob ; López Cobá, Carlos | MDPI AG | 2015-12We present here a review of the latest results on the spatially-resolved analysis of the stellar populations and ionized gas of disk-dominated galaxies based on Calar Alto Legacy Integral Field Area (CALIFA) data. CALIFA is an ongoing integral f[...]texto impreso
Context. The study of the integrated properties of star-forming galaxies is central to understand their formation and evolution. Some of these properties are extensive and therefore their analysis require totally covering and spatially resolved [...]texto impreso

As part of the ongoing CALIFA survey, we have conducted a thorough bidimensional analysis of the ionized gas in two E/S0 galaxies, NGC 6762 and NGC 5966, aiming to shed light on the nature of their warm ionized ISM. Specifically, we present opti[...]texto impreso
We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (?10^11 M_?) gas-rich spirals NGC 4676A and B, observed between first passage and final coalescence. The spectra provide stellar an[...]texto impreso
Context. Galaxies, which often contain ionised gas, sometimes also exhibit a so-called low-ionisation nuclear emission line region (LINER). For 30 years, this was attributed to a central mass-accreting supermassive black hole (more commonly know[...]texto impreso
Marino, Raffaella Anna ; Gil de Paz, Armando ; Castillo Morales, África ; otros, ... | EDP Sciencies | 2013-11The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies, both locally and at high redshift. Many studies have used these fluxes to derive the [...]texto impreso
We have studied the radial structure of the stellar mass surface density (??) and stellar population age as a function of the total stellar mass and morphology for a sample of 107 galaxies from the CALIFA survey. We applied the fossil record met[...]texto impreso
We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morphological signatures of interaction, and coalesced merger remnant[...]
