    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.

    • Radial Velocities in the Outermost Disk toward the Anticenter
      We measure the mean Galactocentric radial component of the velocity of stars (v R ) in the disk at 8 kpc R 28 kpc in the direction of the anticenter. For this, we use the Apache Point Galactic Evolution Experiment. Furthermore, we compare the result with H I maps along the same line of sight. We find an increase in positive (expansion) v R at R ≈

    • Characterization of a subsample of the Planck SZ source cluster catalogues using optical SDSS DR12 data
      Aims: The Planck catalogues of Sunyaev -Zeldovich (SZ) sources, PSZ1 and PSZ2, are the largest catalogues of galaxy clusters selected through their SZ signature in the full sky. In 2013, we started a long-term observational programme at Canary Island observatories with the aim of validating ˜500 unconfirmed SZ sources. In this work we present

      We report detection of the binary companion to the millisecond pulsar J2302+4442 based on the deep observations performed with the Gran Telescopio Canarias. The observations revealed an optical source with r' = 23.33 ± 0.02 and i' = 23.08 ± 0.02, whose position coincides with the pulsar radio position. By comparing the source colour and magnitudes

      We introduce VLT-MUSE observations of the central 2'× 2' (30 × 30 pc) of the Tarantula Nebula in the Large Magellanic Cloud. The observations provide an unprecedented spectroscopic census of the massive stars and ionised gas in the vicinity of R136, the young, dense star cluster located in NGC 2070, at the heart of the richest star-forming region

    • Disk stars in the Milky Way detected beyond 25 kpc from its center
      Context. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at Galactocentric distances R ≳ 15 kpc, which means that in practice no disk stars or only very few of them should be found beyond this limit. However, stars in the Milky Way plane are detected

      We present a three dimensional velocity analysis of Milky Way disc kinematics using LAMOST K giant stars and the GPS1 proper motion catalogue. We find that Galactic disc stars near the anticentre direction (in the range of Galactocentric distance between R = 8 and 13 kpc and vertical position between Z = -2 and 2 kpc) exhibit asymmetrical motions

A set of 20 extremely red galaxies at 2.5 ≤ zphot. ≤ 3.8 with photometric features of old passive-evolving galaxies without dust, with stellar masses of 1011M⊙, have colors that could be related to passive-evolving galaxies with mean ages larger than 1 Gyr. This suggests they have been formed, on average, when the Universe was very young (

      The stellar density distribution of the bulge is analyzed through one of its tracers. We use oxygen-rich Mira variables from the Catchpole et al. survey and OGLE-III survey as standard candles. The average age of these stars is around 9 Gyr. The population traced by Mira variables matches a boxy bulge prediction, not an X-shaped one, because only

      We have analyzed a sample of 327 clusters of galaxies, spanning the range of 0.06–0.70 in redshift. Strong constraints on their mean intracluster emission of dust have been obtained using maps and catalogs from the Herschel MerMES project; within a radius of 5 arcmin centered in each cluster, the 95% C.L. limits obtained are 86.6, 48.2, and 30.9

      The formation of relativistic jets by an accreting compact object is one of the fundamental mysteries of astrophysics. Although the theory is poorly understood, observations of relativistic jets from systems known as microquasars (compact binary stars) have led to a well established phenomenology. Relativistic jets are not expected to be produced

      PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and γ-rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which is very similar to that of the Vela pulsar. The Dragonfly is likely associated with the extended TeV source VER J2019+368 and extended radio emission. We conducted first
