Filter Results
  • Empirical stellar flux scales

    Several studies have appeared in the literature describing methods for deriving stellar continuum fluxes as simple functions of Johnson color indices. In previous papers, we...
  • Study of NGC 300 objects with dendogram

    Integral field units enable resolved studies of a large number of star-forming regions across entire nearby galaxies, providing insight on the conversion of gas into stars and...
  • Galaxy clusters redshifts with VLT/MUSE

    We present strong-lensing analyses of three galaxy clusters, RX J2129.4 + 0009 (z = 0.235), MS 0451.6 - 0305 (z = 0.55), and MACS J2129.4 - 0741 (z = 0.589), using the powerful...
  • Study of relativistic jets in blazar objects

    Our understanding of the unification of jetted AGN has evolved greatly as jet samples have increased in size. Here, based on the largest-ever sample of over 2000 well-sampled...
  • Parameters of 1183 A and F stars

    Previous studies of the rotation law in the outer Galactic disc have mainly used gas tracers or clump giants. Here, we explore A and F stars as alternatives: these provide a...
  • M31 center emission-line point-like sources

    We present a detailed description of the wavelength, astrometric and photometric calibration plan for SITELLE, the imaging Fourier transform spectrometer attached to the...
  • ALHAMBRA fields type-I AGN with ELDAR

    We present ELDAR, a new method that exploits the potential of medium- and narrow-band filter surveys to securely identify active galactic nuclei (AGN) and determine their...
  • Faint emission lines in M16, M20, NGC 3603

    We present deep echelle spectrophotometry of the Galactic HII regions M16, M20 and NGC 3603. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle...
  • Spectrophotometry of the HII region S311

    We present echelle spectrophotometry of the Galactic H II region S311. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Spectrograph in the...
  • Integrated Spectra of Open Clusters

    We present a library of 39 open cluster optical/near-IR integrated spectra. The data were obtained at CASLEO (San Juan, Argentina) and LNA (Itajuba, Brazil). Eight additional...
  • Methyl acetylene observations of warm clouds

    The results of a survey of 63 galactic star-forming region in the 6k-5k and 5k-4k methyl acetylene lines at 102.5 and 85.5GHz are presented. Fourty-three sources were detected...
  • Methanol maser condensations in W 48

    The methanol-line spectra in two maser condensations at velocities ~41 and ~45km/s in the star-forming region W 48 have been studied. Cone search capability for table...
  • Equatorial spectrophotometric standards

    Spectral energy distributions for 41 stars, 7-8mag, near the celestial equator (DE=+/-3{deg}) were obtained. The 3100-7600{AA} spectral range is studied with a spectral...
  • Spectrophotometric standards near DE=+40{deg}

    The second stage to compile a list of regional intermediate-brightness spectrophotometric standards has been completed. It includes the spectral energy distribution for 24 stars...
  • Energy distribution of O9-B5 stars

    The normal spectral energy distribution for spectral subtypes from O4 to O8 and O9 to B5 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs...
  • Energy distribution of O5-O8 stars

    The normal spectral energy distribution for spectral subtypes from O4 to O8 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs served as the...
  • Primary Spectrophotometric Standards

    A spectrophotometric catalog of 238 bright stars was compared with the Tyan Shan photometric catalog in the WBVR system. An analysis of the photometry of ten stars in four...
  • Spectrophotometric Standards near the Pole

    Absolute energy distributions for 13 circumpolar ({delta}>+85deg) stars forming a spectrophotometric version of the North Polar Spectrophotometric Sequence (NPSS) are...
  • Far-UV Point Sources from FAUST

    We list the photometric measurements of point sources made by the Far Ultraviolet Space Telescope (FAUST) when it flew on the ATLAS-1 space shuttle mission. The list contains...
  • Galaxy clusters in the SDSS-DR5

    Recent large-scale galaxy spectroscopic surveys, such as the Sloan Digital Sky Survey (SDSS), enable us to execute a systematic, relatively unbiased search for galaxy clusters....
