  • Catalog of radio galaxies with z>0.3

    This catalog groups the 2442 galaxies making up the sample of distant galaxies prepared by the authors published as 3 papers in 2009: radio data (paper I, table1), photometric...
  • Catalog of radio galaxies with z>0.3

  • NGC 225 CCD UBV photometry

    We present the results of CCD UBV photometric and spectroscopic observations of the open cluster NGC 225. In order to determine the structural parameters of NGC 225, we...
  • The VVV near-IR galaxy catalogue

    Knowledge about the large-scale distribution of galaxies is far from complete in the Zone of Avoidance (ZoA), which is mostly due to high interstellar extinction and to source...
  • Compact radio sources in the SCORPIO field

    We present observations of a region of the Galactic plane taken during the Early Science Program of the Australian Square Kilometre Array Pathfinder (ASKAP). In this context, we...
  • HI global scaling relations in WISE-WHISP

    We present the global scaling relations between the neutral atomic hydrogen gas, the stellar disc, and the star-forming disc in a sample of 228 nearby galaxies that are both...
  • Very young galaxies in the local Universe

    In the local Universe, there are a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a...
  • 28-40GHz variability and polarimetry

    We observed 51 sources in the Q-U-I JOint TEnerife (QUIJOTE) cosmological fields which were brighter than 1Jy at 30GHz in the Planck Point Source Catalogue (version 1), with the...
  • Census of circumgalactic MgII at redshift z=<0.5

    This paper presents a survey of MgII absorbing gas in the vicinity of 380 random galaxies, using 156 background quasi-stellar objects (QSOs) as absorption-line probes. The...
  • Action-space clustering on stellar stream data

    Stream stars removed by tides from their progenitor satellite galaxy or globular cluster act as a group of test particles on neighbouring orbits, probing the gravitational field...
  • Period-luminosity-metallicity relation of RRLs

    This paper presents results from photometric and statistical-parallax analysis of a sample of 850 field RR Lyrae (RRL) variables. The photometric and spectroscopic data for our...
  • Sub-damped Lyman {alpha} systems in XQ-100 II

    We present the measured gas-phase metal column densities in 155 sub-damped Ly {alpha} systems (subDLAs) with the aim to investigate the contribution of subDLAs to the chemical...
  • Evolutionary traits for stellar phylogeny

    Since chemical abundances are inherited between generations of stars, we use them to trace the evolutionary history of our Galaxy. We present a robust methodology for creating a...
  • The VMC survey XLI - PMs within the SMC

    We used data from the near-infrared Visible and Infrared Telescope for Astronomy (VISTA) survey of the Magellanic Cloud system (VMC) to measure proper motions (PMs) of stars...
  • Giant stars in TESS continuous viewing zones

    The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We...
  • SuperWASP variable stars

    We present the first analysis of results from the SuperWASP variable stars Zooniverse project, which is aiming to classify 1.6 million phase-folded light curves of candidate...
  • COMBS Survey. Metal-poor bulge stars

    The metal-poor stars in the bulge are important relics of the Milky Way's formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In...
  • New classical Ae stars using LAMOST DR5

    We report the first systematic study to identify and characterize a sample of classical Ae stars in the Galaxy. The spectra of these stars were retrieved from the A-star...
  • Temperature and metallicity scale of cool giants

    We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the K band for stellar population studies. In this study,...
  • The complete Arecibo Ultra-Deep Survey

    The Arecibo Ultra-Deep Survey (AUDS) is a blind HI survey aimed at detecting galaxies beyond the local Universe in the 21-cm emission line of neutral hydrogen (HI). The Arecibo...
