  • The 236.6-5400.0nm spectrum of CrI

    Precision laboratory measurements are presented for 1963 CrI lines spanning the near-ultraviolet into the thermal infrared. Classifications, based on the analysis by Kiess...
  • CaII spectroscopy of SMC red giants. IV.

    This paper represents a major step forward in the systematic and homogeneous study of Small Magellanic Cloud (SMC) star clusters and field stars carried out by applying the...
  • Ly-Alpha Forest spectra simulation analysis. I.

    We present moderate-resolution (~50km/s FWHM) spectra of the Ly-alpha forest for seven quasars with redshifts ranging from 2.53 to 3.13, obtained with the Blue Spectrograph and...
  • Main galaxy groups from SDSS-DR5

    We investigate the correlations between galaxy properties and environment. From the main galaxy sample of the SDSS Data Release 5, we have extracted 11 163 groups at the linking...
  • Radial velocities of 29 cataclysmic variables

    We report follow-up spectroscopy of 29 cataclysmic variables from the Sloan Digital Sky Survey (SDSS), 22 of which were discovered by SDSS and seven of which are previously...
  • CONCH-SHELL catalog of nearby M dwarfs

    We present an all-sky catalogue of 2970 nearby (d<~50pc), bright (J<9) M- or late K-type dwarf stars, 86% of which have been confirmed by spectroscopy. This catalogue will...
  • Variations in supernova yields

    Theoretical nucleosynthetic yields from supernovae are sensitive to both the details of the progenitor star and the explosion calculation. We attempt to comprehensively identify...
  • Chandra observations of Monoceros R2

    We report on the results of the Chandra ACIS-I observation on the central region of the Monoceros R2 cloud (Mon R2), a high-mass star-forming region (SFR) at a distance of...
  • 72 WINGS nearby clusters luminosity functions

    Using V band photometry of the WINGS survey, we derive galaxy luminosity functions (LF) in nearby clusters. This sample is complete down to M_V_=-15.15, and it is homogeneous,...
  • BR photometry in Coma, A2199 & AWM5 clusters

    We present the results of a study on galaxy interactions, tides, and other processes that produce luminous fine-scale substructures in the galaxy clusters: Coma, Perseus, Abell...
  • ICRF3 radio-loud quasars with Gaia DR2 data

    We investigate a sample of 3413 International Celestial Reference Frame (ICRF3) extragalactic radio-loud sources with accurate positions determined by very long baseline...
  • Einstein HRI Photon Event Data

    The HRIPHOT database contains information from the High Resolution Imager aboard HEAO-2, the Einstein Observatory, in Event List Format. Einstein incorporated a high-resolution...
  • Members of 5 cluster in Ori OB1a association

    The Orion complex is arguably the most studied star-forming region in the Galaxy. While stars are still being born in the Orion nebula, the oldest part was believed to be no...
  • PAndAS view of Andromeda satellites. I.

    We present a generic algorithm to search for dwarf galaxies in photometric catalogs and apply it to the Pan-Andromeda Archaeological Survey (PAndAS). The algorithm is developed...
  • Multiwavelength survey of WR stars in LMC

    Surveys of Wolf-Rayet (WR) stars in the Large Magellanic Cloud (LMC) have yielded a fairly complete catalog of 154 known stars. We have conducted a comprehensive,...
  • MCG Vol.5

    The Morphological Catalogue of Galaxies, Volume 5 (Vorontsov-Velyaminov et al. 1974) includes 1637 galaxies, probably no fainter than the fourteenth magnitude. The catalog was...
  • Calcium triplet index in LMC stars

    Infrared CaII triplet (CaT) spectroscopy has been used to derive stellar metallicities for individual stars in four Large Magellanic Cloud fields situated at galactocentric...
  • EW of 4 primary stars and the Sun

    Study of primary stars lying in Sirius-like systems with various masses of white dwarf (WD) companions and orbital separations is one of the key aspects to understand the origin...
  • UV to far-IR photometry of galaxies

    In this paper, we present a sample of cluster galaxies devoted to study the environmental influence on the star formation activity. This sample of galaxies inhabits in clusters...
