    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.

    • Diagonal Ridge Pattern of Different Age Populations Found in Gaia-DR2 with LAMOST Main-sequence Turnoff and OB-type Stars

      We revisit the diagonal ridge feature (diagonal distributions in the R, vφ plane) found in Gaia and present a timing analysis for it between Galactocentric distances of R = 7.5 and 12 kpc, using main-sequence turnoff and OB stars selected from the LAMOST Galactic spectroscopic surveys. We recover the ridge pattern in the R-vφ plane color coded by

    • Gaia-DR2 extended kinematical maps. III. Rotation curves analysis, dark matter, and MOND tests

      Context. Recent statistical deconvolution methods have produced extended kinematical maps in a range of heliocentric distances that are a factor of two to three larger than those analysed in Gaia Collaboration (2018, A&A, 616, A11) based on the same data. Aims: In this paper, we use such maps to derive the rotation curve both in the Galactic plane

      By combining LAMOST DR4 and Gaia DR2 common red clump stars with age and proper motion, we analyze the amplitude evolution of the stellar warp independently of any assumption with a simple model. The greatest height of the warp disk increases with galactocentric distance in different populations and is dependent on age: the younger stellar

      Context. The structure of outer disc of our Galaxy is still not well described, and many features need to be better understood. The second Gaia data release (DR2) provides data in unprecedented quality that can be analysed to shed some light on the outermost parts of the Milky Way.

      Context. Core extremely red quasars (core ERQ) have been proposed to represent an intermediate evolutionary phase in which a heavily obscured quasar blows out the circumnuclear interstellar medium with very energetic outflows before it becomes an optical quasar. Aims: We investigate whether the properties of core ERQ fit the AGN orientation-based

      We report on multiband photometric observations of four binary millisecond pulsars with the Gran Telescopio Canarias. The observations led to detection of binary companions to PSRs J1630+3734, J1741+1351, and J2042+0246 in the Sloan g', r', and i' bands. Their magnitudes in the r' band are ≈24.4, 24.4, and 24.0, respectively. We also set a 3σ upper

      Galaxy velocity mapsoften show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the galactic center. The simplest template used to fit these maps consists in the rotating disk model (RDM) where the amplitude of circular velocities is fixed by the observed velocity profile
