  • Spectrophotometry of 77 variable stars

    The results of visual and near-infrared spectrophotometric observations for 77 variable stars obtained during 1971-1991 in Chile, Armenia and Bolivia. The quasi-monochromatic...
  • HR-PYPOPSTAR model

    We present the HR-PYPOPSTAR model, which provides a complete set (in ages) of high-resolution (HR) spectral energy distributions of Single Stellar Populations. The model uses...
  • PNe angular diameters from SED modeling

    Powerful new, high-resolution, high-sensitivity, multifrequency, wide-field radio surveys such as the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of...
  • 1ES 2344+514 Multi-wavelength study

    Extreme High-frequency BL Lacs (EHBL) feature their synchrotron peak of the broadband spectral energy distribution (SED) at {nu}s>=10^17^Hz. The BL Lac object 1ES 2344+514...
  • The 2BIGB gamma-ray blazars catalog

    This paper presents the results of a {gamma}-ray likelihood analysis over all the extreme and high synchrotron peak blazars (EHSP and HSP) from the 3HSP catalogue. We...
  • Spectral energy distributions of AGNs

    We present spectral energy distributions (SEDs) of 41 active galactic nuclei, derived from multiwavelength photometry and archival spectroscopy. All of the SEDs span at least...
  • Low-frequency study of 3C 31 with LOFAR

    We present a deep, low-frequency radio continuum study of the nearby Fanaroff-Riley class I (FR I) radio galaxy 3C 31 using a combination of LOw Frequency ARray (LOFAR; 30-85...
  • Parameters and IR excesses of Gaia DR1 stars

    Effective temperatures and luminosities are calculated for 1,475,921 Tycho-2 and 107,145 Hipparcos stars, based on distances from Gaia Data Release 1. Parameters are derived by...
  • Intrinsic AGN SEDs in PG quasars

    We present a new analysis of the Palomar-Green quasar sample based on Spitzer and Herschel observations. (i) Assuming polycyclic aromatic hydrocarbon (PAH)-based star formation...
  • TP-AGB stars contribution in SFR

    We study the debated contribution from thermally pulsing asymptotic-giant-branch (TP-AGB) stars in evolutionary population synthesis models. We investigate the spectral energy...
  • SEDs of type I AGN in XMM-COSMOS. II.

    The mid-infrared-to-ultraviolet (0.1-10{mu}m) spectral energy distribution (SED) shapes of 407 X-ray-selected radio-quiet type 1 active galactic nuclei (AGN) in the wide-field...
  • QSOs SED shapes from optical to NIR

    We define a quasar-galaxy mixing diagram using the slopes of their spectral energy distributions (SEDs) from 1{mu}m to 3000{AA} and from 1 to 3{mu}m in the rest frame. The...
  • SED of K+A galaxies from UV to mid-IR

    We present spectrum synthesis fits to 808 K+A galaxies selected from the Sloan Digital Sky Survey (SDSS) and population synthesis of their spectral energy distributions,...
  • 86 Herschel sources SED model parameters

    We present spectral energy distributions (SEDs) for 86 Herschel sources detected at 5{sigma} at 250, 350 and 500um in the HerMES SWIRE-Lockman field. We explore whether existing...
  • MILES base models & new line index system

    We present synthetic spectral energy distributions (SEDs) for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at moderately...
  • SED of 180 SIMBA 1.2mm sources

    Concatenating data from the millimetre regime to the infrared, we have performed spectral energy distribution (SED) modelling for 227 of the 405 millimetre continuum sources of...
  • 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...
  • Spectrophotometry of S and carbon stars

    The absolute energy distributions in the visual spectra (3200-7600{AA}) of 13 N carbon stars and three S stars have been investigated. The spectral resolution of the data is 50...
  • 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...
