  • Catalogue of ULX's line features

    Most ultraluminous X-ray sources (ULXs) are thought to be powered by super- Eddington accretion on to stellar-mass compact objects. Accretors in this extreme regime are...
  • 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...
  • 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...
  • 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...
  • 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...
  • 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...
  • Surveys of clumps & cores in Cygnus X. I. ~0.1pc MDCs

    Using infrared to (sub)millimeter data from Spitzer, Herschel, the James Clerk Maxwell Telescope, and the IRAM 30m telescope, we conducted an unbiased survey of the massive...
  • 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,...
  • The Herschel Orion Protostar Survey (HOPS): SEDs

    We present key results from the Herschel Orion Protostar Survey (HOPS): spectral energy distributions (SEDs) and model fits of 330 young stellar objects, predominantly...
  • Spectral energy distributions of Roma BZCAT blazars

    We combined multi-wavelength data for blazars from the Roma-BZCAT catalog and analyzed hundreds of X-ray spectra. We present the fluxes and spectral energy distributions (SEDs),...
