  • WASP-31b:HST/Spitzer transmission spectral survey

    We present Hubble Space Telescope optical and near-IR transmission spectra of the transiting hot-Jupiter WASP-31b. The spectrum covers 0.3-1.7 {mu}m at a resolution R~70, which...
  • ExoMol line lists for phosphine (PH_3_)

    A comprehensive hot line list is calculated for ^31^PH_3_ in its ground electronic state. This line list, called SAlTY, contains almost 16.8 billion transitions between 7.5...
  • Giant Gemini GMOS survey. I.

    We present spectra of 163 quasars at z_em_>4.4 taken with the Gemini Multi Object Spectrometers, the largest publicly available sample of high-quality (signal-to-noise ratio...
  • HII complexes optical and IR emissions

    We present an analysis of optical spectroscopy and infrared aperture photometry of more than 100 HII complexes in nine galaxies. Spectra obtained with the 6-m telescope of...
  • Velocities and EW of PTF SNe Ia

    We present an investigation of the optical spectra of 264 low-redshift (z<0.2) Type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory, an untargeted...
  • Early-Type Galaxies in SDSS and GALEX

    We use the Hernandez-Perez and Bruzual stellar population synthesis models to study the role of interacting binary pairs as progenitors of extreme horizontal branch (EHB) stars....
  • Kapteyn's star spectroscopic measurements

    Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of...
  • Warm molecular hydrogen in ULIRGs

    Ultraluminous infrared galaxies (ULIRGs) show on average three times more emission in the rotational transitions of molecular hydrogen than expected based on their star...
  • Post-AGB/RGB and YSOs in SMC

    We have carried out a search for optically visible post-asymptotic giant branch (post-AGB) candidates in the Small Magellanic Cloud (SMC). First, we used mid-IR observations...
  • Mid-IR QSO spectral templates

    Mid-infrared (MIR) quasar spectra exhibit a suite of emission features including high ionization coronal lines from the narrow-line region illuminated by the ionizing continuum,...
  • VY CMa molecular line spectra

    We present an analysis of the far-infrared and submillimetre molecular emission-line spectrum of the luminous M-supergiant VY CMa, observed with the Spectral and Photometric...
  • RMS survey: molecular observations

    We have used the well-selected sample of ~1750 embedded, young, massive stars identified by the Red MSX Source (RMS) survey to investigate the Galactic distribution of recent...
  • Extremely faint planetary nebulae in SDSS

    Using ~1700000 target- and sky-fibre spectra from the Sloan Digital Sky Survey (SDSS), we have carried out a systematic search for Galactic planetary nebulae (PNe) via...
  • z~6 QSOs CIV doublet absorption systems

    We present the results of observations taken with the X-shooter spectrograph devoted to the study of quasars at z~6. This paper focuses on the properties of metals at high...
  • Velocities in ZwCl2341.1+0000 field

    We study the dynamical status of the galaxy system ZwCl 2341.1+0000, a filamentary multi-Mpc galaxy structure associated with a complex diffuse radio emission. Our analysis is...
  • ExoMol line lists for SiO

    Accurate rotation-vibration line lists are calculated for silicon monoxide. Line lists are presented for the main isotopologue, ^28^Si^16^O, and four monosubstituted...
  • Variability of broad emission lines in QSOs

    We examine the variability of the high-ionization Ly{alpha} {lambda}1216 broad emission line (BEL) in a sample of 61 high-luminosity, high-redshift quasars observed at two...
  • 76 T dwarfs from the UKIDSS LAS

    We report the discovery of 76 new T dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS). Near-infrared broad- and narrow-band photometry and...
  • Type 1 AGN at low z. III.

    We present the optical narrow-line ratios in a Sloan Digital Sky Survey (SDSS) based sample of 3175 broad H{alpha} selected type 1 active galactic nuclei (AGN), and explore...
  • H{alpha} fluxes of Galactic planetary nebulae

    We present a catalogue of new integrated H{alpha} fluxes for 1258 Galactic planetary nebulae (PNe), with the majority, totalling 1234, measured from the Southern H{alpha} Sky...
