  • Final Merged Log of IUE Observations

    The log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at Vilspa. It was constructed by using verified data from the...
  • Population Synthesis Models at very low metallicities

    Using new sets of stellar evolution models at very low metallicities (Z=10^-7^; 10^-5^) and previously published grids we examine spectral properties of the ionising continua,...
  • The FUSE Observation Log

    Funded by NASA as part of its Origins program, FUSE was developed in collaboration with the space agencies of Canada and France, and is being operated for NASA by the Johns...
  • Merged Log of IUE Observations

    The log contains data from January 26, 1978 through Dec. 92. It is sorted by right ascension.
  • UVILLSS Catalogue

    This catalogue is an extension in the ultraviolet region (129 to 3903 Angstroems) of the ILLSS catalogue (Coluzzi, 1993; catalog ) which lists lines in the optical region. The...
  • Merged Log of IUE Observations

    The log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at Vilspa. It was constructed by using verified data from the...
  • Kazarian galaxies catalog

    The entire KG (KG) catalog is presented which combines extensive new measurements of their optical parameters with a literature and database search. The measurements were made...
  • X-ray-to-FIR SED data in W-CDF-S, ELAIS-S1 & XMM-LSS

    W-CDF-S, ELAIS-S1, and XMM-LSS will be three Deep-Drilling Fields (DDFs) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), but their extensive...
  • Nature of the peculiar supergiant HD 101584

    We present a study of low- and high-resolution ultraviolet, high-resolution optical CAT/CES spectra and ultraviolet, optical and infrared photometry of the peculiar supergiant...
  • HST/STIS spectra of alpha Cen A

    This table is part of a paper is which a study of the alpha Cen A spectrum recorded with the E140 grating by HST/STIS between 1140 and 1670{AA} is presented. In this spectrum...
  • Mount Wilson index for main sequence F-K stars

    The largest dataset of stellar activity measurements available at present is the one obtained at the Mount Wilson Observatory, where high-precision CaII H+K fluxes have been...
  • Imaging GRB 980425 in millimetric and submm

    Gamma-ray bursts (GRBs) have been proposed as a tool to study star formation in the Universe, so it is crucial to investigate whether their host galaxies and immediate...
  • Cas A LOFAR and VLA images

    Cassiopeia A is one of the best-studied supernova remnants. Its bright radio and X-ray emission is due to shocked ejecta. Cas A is rather unique in that the unshocked ejecta can...
  • EUV irradiances of the quiet Sun

    We benchmark new atomic data against a selection of irradiances obtained from medium-resolution quiet-Sun spectra in the extreme ultraviolet (EUV), from 60 to 1040{AA}. We used...
  • O(3P) + H2(v, j)-->OH + H:OH reactions

    The reaction between atomic oxygen and molecular hydrogen is an important one in astrochemistry as it regulates the abundance of the hydroxyl radical and serves to open the...
  • Hubble spectroscopy of LB-1 (LS V +22 25)

    LB-1 has variously been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary, or a Be star plus an inflated stripped star (Be+Bstr) binary. The Space...
  • Most massive stars and their clumped winds

    The star cluster R136 inside the Large Magellanic Cloud hosts a rich population of massive stars, including the most massive stars known. The strong stellar winds of these very...
  • Quasars as high-redshift standard candles

    The non-linear relation between the X-ray and ultraviolet (UV) luminosity in quasars has been used to derive quasar distances and to build a Hubble diagram at redshifts up to...
  • Low-Redshift Lyman Continuum Survey

    Combining 66 ultraviolet (UV) spectra and ancillary data from the recent Low-Redshift Lyman Continuum Survey (LzLCS) and 23 LyC observations by earlier studies, we form a...
  • FUV imaging of Dorado galaxies

    We are investigating the star formation in galaxies of the actively evolving Dorado group where, for a large fraction of both early- and late-type galaxies, signatures of...
