  • 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...
  • 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...
  • 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...
  • Energy distribution of main-sequence B stars

    The normal spectral energy distribution in the spectra of main-sequence B stars of five subclasses is presented. Spectral classification and UBV photometry from the fourth...
  • Energy distribution in giants and supergiants.

    The energy distributions for 27 giants and supergiants of the M spectral type are presented in the region of 3200-7600{AA} with the step of 50{AA}. The observations were made in...
  • Energy distribution of G,K and M stars

    A large number of stars from photometrically homogeneous catalogs are used to derive the normal energy distribution for giants of 15 spectral subclasses. To judge the...
  • FUV to FIR phot. of massive galaxies in SDSS Stripe 82

    The broadband spectral energy distribution of a galaxy encodes valuable information on its stellar mass, star formation rate (SFR), dust content, and possible fractional energy...
  • Time evolution of Mrk501 emission during 2017-2020

    We study the broadband emission of Mrk 501 using multiwavelength observations from 2017 to 2020 performed with a multitude of instruments, involving, among others, MAGIC,...
  • Extension of HOPS out to 500pc (eHOPS). I. Aquila

    We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d~436pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500...
  • Stellar radii & extinctions from APOGEE, GALAH & RAVE

    Asteroseismology has become widely accepted as a benchmark for accurate and precise fundamental stellar properties. It can therefore be used to validate and calibrate stellar...
  • ALMA survey of Orion PGCCs (ALMASOP). II. 1.3mm

    Planck Galactic Cold Clumps (PGCCs) are considered to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside...
  • X-ray, opt. & radio SEDs of Fermi blazars

    In this paper, multiwavelength data are compiled for a sample of 1425 Fermi blazars to calculate their spectral energy distributions (SEDs). A parabolic function,...
