  • Disc galaxies since z=1 sizes

    Our understanding of how the size of galaxies has evolved over cosmic time is based on the use of the half-light (effective) radius as a size indicator. Although the half-light...
  • Morphology of COSMOS -UltraVISTA -DASH galaxies

    By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H-band-selected massive galaxies in the...
  • DES Y3 low surface brightness galaxies

    Low surface brightness galaxies (LSBGs) which are defined as galaxies that are fainter than the night sky, play a crucial role in understanding galaxy evolution and cosmological...
  • Stripping & unwinding galaxies from WINGS surveys

    Ram pressure stripping is one of the most efficient mechanisms able to affect the gas reservoir in cluster galaxies, and in the last decades many studies have characterized the...
  • The Guide Star Catalog, Version 2.4.2 (GSC2.4.2)

    The GSC II is an all-sky catalog based on 1" resolution scans of the photographic Sky Survey plates, at two epochs and three bandpasses, from the Palomar and UK Schmidt...
  • Isolated Pairs of Galaxies in Northern Hemisphere

    The catalog is a compilation of observational data for 603 isolated pairs of galaxies with component magnitudes brighter than 15.7 and north of declination -3 degrees. The...
  • Morphological Cat. of Gal. (MCG)

    The catalog is a compilation of information for approximately 34000 galaxies found and examined on the Palomar Observatory Sky Survey (POSS). Individual identifiers are assigned...
  • Second Byurakan Survey. General Catalogue

    The Second Byurakan Survey (SBS) General Catalogue is presented. The SBS, a continuation of the Markarian survey reaching fainter limiting magnitudes, is the first survey which...
  • COSMOS Morphological Catalog (V1.1)

    The zCOSMOS field benefits of high-resolution imaging in the F814W filter from the HST-ACS (Advanced Camera for Survey). We use standard morphology classifiers, optimised for...
  • Second Byurakan Survey galaxies. Optical database

    A database for the entire catalog of the Second Byurakan Survey (SBS) galaxies is presented. It contains new measurements of their optical parameters and additional information...
  • 2MASS-selected Isolated Galaxies (2MIG)

    We undertook searches for isolated galaxies based on automatic selection of infrared sources from the Two Micron All-Sky Survey (2MASS, Cat. II/246) followed by a visual...
  • GOODS Morphological Catalog

    We present below the morphological catalogs of galaxies in the GOODS North and South fields, as determined visually by R. S. Ellis with a magnitude limit from HST/ACS imaging of...
  • Revised Flat Galaxy Catalogue (RFGC)

    The Flat Galaxy Catalog (FGC) is the result of a systematic search for disk-like edge-on galaxies with a diameter larger than a=40arcsec and major-to-minor axis ratio a/b>7...
  • Survey of 108 E-S0 galaxies

    A survey has been performed of the morphological and photometric properties of 108 E-S0 galaxies out of a complete sample of 112: this sample is built from the Revised...
  • Morphological type catalog in 55 rich galaxy clusters

    Data are presented from a study of 55 rich clusters of galaxies. The data include positions, morphological types, estimated total magnitudes, bulge sizes, and ellipticities for...
  • Surface Photometry of ESO-Uppsala Galaxies

    The 15467 southern galaxies in this catalog were scanned from 407 blue and 407 red original ESO-Schmidt plates using a PDS microdensitometer. The galaxies were selected from the...
  • 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...
  • Simulation Atlas of Tidal Features in Galaxies

    The simulation survey of tidally perturbed galaxies provides images of 84 different encounters that vary orbit tilt of companion orbit, perigalacticon distance ratio of primary...
  • Star clusters in IC 10

    Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we...
  • New dwarf galaxies in northern groups

    We have searched for nearby dwarf galaxies in 27 northern groups with characteristic distances 8-15Mpc based on the Second Palomar Sky Survey prints. In a total area of about...
