    Spectroscopic Classification of Late-M and L Field Dwarfs
    We present spectra for 12 new ultracool dwarfs found in the DENIS infrared survey. Seven of them have spectral types at the bottom of the M-class (M8-M9.5), and...

    Spectroscopic classification of red high proper motion objects in the Southern Sky
    We present the results of spectroscopic follow-up observations for a sample of 71 red objects with high proper motions in the range 0.08-1.14 arcsec yr-1 as...
  • Publication
    Spectroscopic classification of X-ray selected stars in the rho Ophiuchi star-forming region and vicinity
    We present intermediate-resolution (FWHM~1.5-2.6 Angstroms) optical spectra of 106 candidate optical counterparts of 77 X-ray sources detected in four pointed...
  • Publication
    Spectroscopic classification of X-ray sources in the Galactic Bulge Survey
    We present the classification of 26 optical counterparts to X-ray sources discovered in the Galactic Bulge Survey. We use (time-resolved) photometric and...
  • Publication
    Spectroscopic Confirmation of an Ultra Massive and Compact Galaxy At Z = 3.35: a Detailed Look At an Early Progenitor of Local Giant Ellipticals
    We present the first spectroscopic confirmation of an ultramassive galaxy at redshift z\gt 3 using data from Keck-NIRSPEC, VLT-X-shooter, and GTC-Osiris. We...
  • Publication
    Spectroscopic Confirmation of CEERS NIRCam-selected Galaxies at z ≃ 8-10
    We present JWST/NIRSpec prism spectroscopy of seven galaxies selected from Cosmic Evolution Early Release Science (CEERS) survey NIRCam imaging with photometric...
  • Publication
    Spectroscopic determination of intensities of umbral bright features and adjacent background
    Profiles of the Na I D doublet in three bright features (clusters of umbral dots), located in a relatively dark umbra, were analyzed by means of the 'local two...
  • Publication
    Spectroscopic follow-up of L- and T-type proper-motion member candidates in the Pleiades
    We report on the near-infrared (JHK-bands) low-resolution spectroscopy and red optical (Z-band) photometry of seven proper-motion, very low-mass substellar...
  • Publication
    Spectroscopic follow-up of ultraviolet-excess objects selected from the UVEX survey
    We present the results of the first spectroscopic follow-up of 132 optically blue ultraviolet (UV)-excess sources selected from the UV-Excess Survey of the...
