  • The flux rope models checked by some observations
    High resolution H alpha and white light observation of the birth of 73 active regions (AR) were used to check models of sunspots. It is concluded that large AR result from the emergence of a compact and twisted flux rope, while the small ones are produced by the clustering of flux tubes by supergranular motions.

  • The FR II Broad-Line Seyfert 1 Galaxy: PKS J1037-2705
    In this article we demonstrate that PKS J1037-2705 has a weak accretion flow luminosity, well below the Seyfert 1/QSO dividing line, weak broad emission lines (BELs), and moderately powerful FR II extended radio emission. It is one of the few documented examples of a broad-line object in which the time-averaged jet kinetic luminosity, Q, is larger

  • The Gaia mission
    Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by European industry. The involvement of the scientific

  • The GaLAxy Cluster Evolution survey (GLACE): introduction and first results
    Aimed at understanding the evolution of galaxies in clusters, the GLACE survey is mapping a set of optical lines ([OII]3727, [OIII]5007, Hβ and Hα/[NII] when possible) in several galaxy clusters at z ˜ 0.40, 0.63 and 0.86, using the Tuneable Filters (TF) of the OSIRIS instrument (Cepa et al. 2005) at the 10.4 m GTC telescope. This study will

  • The Geometry of the Infrared and X-Ray Obscurer in a Dusty Hyperluminous Quasar
    We study the geometry of the active galactic nucleus (AGN) obscurer in IRAS 09104+4109, an IR-luminous, radio-intermediate FR-I source at z = 0.442, using infrared data from Spitzer and Herschel, X-ray data from NuSTAR, Swift, Suzaku, and Chandra, and an optical spectrum from Palomar. The infrared data imply a total rest-frame 1–1000 μm luminosity

  • The global oscillation spectrum of the sun. I - Analysis of daily power spectra of velocity measurements
    Daily observations of solar global oscillations using a resonant scattering spectrometer have been obtained by observing integral sunlight during the summer seasons of the years 1977 to 1984. The power spectra of the daily residuals are calculated and the mean for each observing season is found. Several discrete frequency intervals are defined in
