    Descripción

    El Proyecto se estructura en dos partes, diferenciadas pero complementarias: morfología y dinámica. El estudio detallado de la morfología de la Vía Láctea pretende proveer una base de datos de distribución estelar en las regiones más alejadas y extintas de nuestra Galaxia, mediante el desarrollo de modelos semiempíricos a partir de la información contenida en dichos catálogos. Por otra parte, los análisis cinemáticos y dinámicos pretenden hacernos entender el origen de esos rasgos que observamos.

    Nuestro grupo ha utilizado la combinación de datos propios (que incluirán en el futuro observaciones espectroscópicas con GRANTECAN/EMIR) con los catálogos públicos fotométricos (DENIS, 2MASS, UKIDSS, VISTA en infrarrojo cercano o SDSS) o espectroscópicos (SDSS-APOGEE en infrarrojo cercano, LAMOST). Se cuenta con información detallada de la distribución estelar de las poblaciones dominantes en una amplia zona de cielo, abarcando diferentes componentes estructurales: bulbo triaxial, barra larga, disco, brazos espirales, etc. Las componentes de gas y polvo son también objeto de estudio en infrarrojo, o en microondas (estudios de contaminación Galáctica al fondo cósmico de microondas, por ejemplo con WMAP o PLANCK). El grupo de investigación se ha integrado también en el nodo español de Gaia con la idea de orientar parte de nuestro trabajo en el aprovechamiento científico de la misión y, en concreto, en la identificación y estudio de poblaciones estelares a gran escala en la Galaxia.

    • Vertical velocities from proper motions of red clump giants

      Aims: We derive the vertical velocities of disk stars in the range of Galactocentric radii of R = 5 - 16 kpc within 2 kpc in height from the Galactic plane. This kinematic information is connected to dynamical aspects in the formation and evolution of the Milky Way, such as the passage of satellites and vertical resonance and determines whether the

      We present the identification and characterization of the optical counterpart to 2XMM J011942.7+032421, one of the most luminous and distant ultra-luminous X-ray sources (ULXs). The counterpart is located near a star-forming region in a spiral arm of the galaxy NGC 470 with u, g, and r magnitudes of 21.53, 21.69, and 21.71 mag, respectively. The

    • On the dust content of galaxy clusters

      Context. Most of the contribution to dust emission in clusters of galaxies comes from late-type galaxies. However, several ejection processes of material from these galaxies could introduce dust in the intracluster media. Even a relatively low abundance of this dust could act as an efficient cooling agent and have a relevant role in the evolution

    • Three-dimensional decomposition of galaxies with bulge and long bar

      Context. Some observations indicate that the Milky Way has two inner components, a bulge and a long bar, which present a misalignment of Δα ≃ 20° that is against the predictions of some theoretical models that are based on numerical simulations. Aims: We wish to determine whether this misalignment between the bar and the bulge can be observed in

    • Dynamical evolution of two associated galactic bars

      We study the dynamical interactions of mass systems in equilibrium under their own gravity that mutually exert and experience gravitational forces. The method we employ is to model the dynamical evolution of two isolated bars, hosted within the same galactic system, under their mutual gravitational interaction. In this study, we present an

    • The triggering mechanism and properties of ionized outflows in the nearest obscured quasars

      We have identified ionized outflows in the narrow-line region of all but one Sloan Digital Sky Survey type 2 quasars (QSO2) at z≲0.1 (20/21, detection rate 95 per cent), implying that this is a ubiquitous phenomenon in this object class also at the lowest z. The outflowing gas has high densities (ne≳1000 cm-3) and covers a region the size of a few

    • Milky Way rotation curve from proper motions of red clump giants

      Aims: We derive the stellar rotation curve of the Galaxy in the range of Galactocentric radii of R = 4-16 kpc at different vertical heights from the Galactic plane of z between -2 and +2 kpc. With this we reach high Galactocentric distances in which the kinematics is poorly known due mainly to uncertainties in the distances to the sources. Methods

    • Infrared Extinction in the Inner Milky Way through Red Clump Giants

      While the shape of the extinction curve in the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be approximately constant, a number of recent studies point to either a spatially variable behavior of the exponent of the power law or a different extinction law altogether. In this paper, we propose

    • Discovery of the Broad-lined Type Ic SN 2013cq Associated with the Very Energetic GRB 130427A

      Long-duration gamma-ray bursts (GRBs) at z < 1 are found in most cases to be accompanied by bright, broad-lined Type Ic supernovae (SNe Ic-BL). The highest-energy GRBs are mostly located at higher redshifts, where the associated SNe are hard to detect observationally. Here, we present early and late observations of the optical counterpart of the

    • Luminosity-colour relations for red clump stars

      We calibrated the absolute magnitudes M V , M J , M_{Ks} and M g of red clump stars in terms of colours. M V and M g are strongly dependent on colour, while the dependence of M J and M_{Ks} on colour is rather weak. The calibration of the absolute magnitudes M V and M_{Ks} is tested on 101 RC stars in the field SA 141. The Galactic model parameters

      The observation of blank fields, defined as regions of the sky that are devoid of stars down to a given threshold magnitude, constitutes one of the most relevant calibration procedures required for the proper reduction of astronomical data obtained following typical observing strategies. In this work, we have used Delaunay triangulation to search

      Aims: We present optical photometry and spectroscopy of the afterglow and host galaxy of gamma-ray burst GRB 040924. This GRB had a rather short duration of T90 ~2.4 s, and a well sampled optical afterglow light curve. We aim to use this dataset to find further evidence that this burst is consistent with a massive star core-collapse progenitor
