  • 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...
  • The C^+^ ion photofragment spectra

    Carbon monoxide (CO) is one of the most abundant molecular species in comets. Its photodissociation by the solar radiation in the vacuum ultraviolet (VUV) region produces...
  • Comet 67P/Churyumov-Gerasimenko FUV aurora

    We aim to determine whether dissociative excitation of cometary neutralsby electron impact is the major source of far-ultraviolet (FUV) emissions at comet...
  • ALPINE-ALMA [CII] survey. IR luminosity

    We present dust attenuation properties of spectroscopically confirmed star forming galaxies on the main sequence at a redshift of ~4.4-5.8. Our analyses are based on the far...
  • UVES spectra of Feige 46 and LSIV -14 116

    Hot subdwarf stars of spectral types O and B represent a poorly understood phase in the evolution of low-mass stars, in particular of close compact binaries. A variety of...
  • ALPINE DR1 merged catalog

    The ALPINE-ALMA large program targets the [CII] 158um line and the far-infrared continuum in 118 spectroscopically confirmed star-forming galaxies between z=4.4 and z=5.9. It...
  • J-PLUS Ly{alpha}-emitting candidates

    We present the photometric determination of the bright-end of the Ly{alpha} luminosity function (at L_Ly{alpha}>~10^43.5^erg/s) within four redshifts windows...
  • Mean rest-UV spectra of Ly{alpha} emitters at z>3

    We investigate the ultraviolet (UV) spectral properties of faint Lyman{alpha} emitters (LAEs) in the redshift range 2.9<=z<=4.6 and provide material to prepare future...
  • GC hot UV-bright stars model spectra

    We have performed a census of the UV-bright population in 78 globular clusters using wide-field UV telescopes. This population includes a variety of phases of post-horizontal...
  • GAS II. UV luminosity functions & InfraRed eXcess

    Dust is a crucial component of the interstellar medium of galaxies. The presence of dust strongly affects the light produced by stars within a galaxy. As these photons are our...
  • HST/COS and FUSE UV spectra of Mrk 509

    To elucidate the location, physical conditions, mass outflow rate, and kinetic luminosity of the outflow from the active nucleus of the Seyfert 1 galaxy Mrk 509 we used...
  • SDSS J151349.52+035211.28 Xshooter spectra

    We present the detection and detailed analysis of a diffuse molecular cloud at z_abs_=2.4636 towards the quasar SDSS J151349.52+035211.28 (hereafter J1513+0352) (zem~=2.68)...
  • HNCO in planetary atmospheres.

    Time-resolved Fourier transform infrared emission spectroscopy, Fourier transform absorption infrared spectroscopy, and high-resolution UV-ViS emission spectroscopy have been...
  • 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...
  • SOLAR/SOLSPEC Spectral Irradiance - 0.5-3000nm

    Since April 5, 2008 and up to February 15, 2017, the SOLar SPECtrometer (SOLSPEC) instrument of the SOLAR payload on board the International Space Station (ISS) has performed...
  • VUV absorption cross section of CO_2_

    We quantify the temperature dependency of the VUV absorption cross section of carbon dioxide. The VUV absorption cross section of CO_2_ increases with the temperature. The...
  • Full spectrum of Proxima Centauri

    The discovery of Proxima b, a terrestrial temperate planet, presents the opportunity of studying a potentially habitable world in optimal conditions. A key aspect to model its...
  • X-shooter spectra of 6 ~2.2 quasars

    We studied the spectra of six z~2.2 quasars obtained with the X-shooter spectrograph at the Very Large Telescope. The redshift of these sources and X-shooter's spectral coverage...
  • IUE continuum fluxes of SY Mus

    Light curves (LCs) of some symbiotic stars show a different slope of the ascending and descending branch of their minimum profile. The origin of this asymmetry is not well...
  • Sun UV spectrum (06/06/2008-26/04/2009)

    The SOLar SPECtrum (SOLSPEC) experiment is part of the Solar Monitoring Observatory (SOLAR) payload, and has been externally mounted on the Columbus module of the International...
