  • Outer disks of S0-Sb gal. II. Surface-brigthness

    We present azimuthally averaged radial profiles of R-band surface brightness for a complete sample of 47 early-type, unbarred galaxies, as a complement to our previous study of...
  • Sizes and luminosities of stellar systems

    We use a combined imaging and spectroscopic survey of the nearby central cluster galaxy, M87, to assemble a sample of 34 confirmed UltraCompact Dwarfs (UCDs) with half-light...
  • LMC star clusters structural parameters

    We present and analyze the radial luminosity profiles of a sample of 1066 stellar clusters in the Large Magellanic Cloud (LMC). By design, this study closely follows the...
  • Photometry of YSOs in eight bright-rimmed clouds

    We carried out deep- and wide-field near- and mid-infrared observations for a sample of eight bright-rimmed clouds (BRCs). Supplemented with the Spitzer archival data, we have...
  • Dwarf galaxies surface brightness profiles. II.

    In this second paper of a series, we explore the B-V, U-B, and FUV-NUV radial color trends from a multi-wavelength sample of 141 dwarf disk galaxies. Like spirals, dwarf...
  • VLA/VLBA obscured radio-loud active galactic nuclei

    This is the second paper directed toward finding new highly redshifted atomic and molecular absorption lines at radio frequencies. To this end, we selected a sample of 80...
  • Rosette Nebula and Maddalena Cloud structures

    We describe an automatic, objective routine for analyzing the clumpy structure in a spectral line position-position-velocity data cube. The algorithm works by first contouring...
  • VI photometry of HST faint field galaxies

    We present a complete morphologically classified sample of 144 faint field galaxies from the HST Medium Deep Survey with 20.0=<Imag<22.0mag. We compare the global...
  • Distances of planetary nebulae

    We describe an improved method for determining the distances of planetary nebulae (PNe) based on a theoretical/empirical relationship between their radii and radio surface...
  • CFRS XI: High-redshift field galaxies morphology

    The 143 galaxies with secure redshifts (Z_median_=0.62) from the 1415+52 field of the Canada-France Redshift Survey have been imaged with median seeing of 0.67" (FWHM)....
  • Tadpole galaxies in the Hubble UDF

    In the Hubble Ultra Deep Field (HUDF, Cat. ) an abundance of galaxies is seen with a knot at one end plus an extended tail, resembling a tadpole. These "tadpole galaxies" appear...
  • HST/NICMOS observations of bright IR galaxies

    We present new results on the physical nature of infrared-luminous sources at 0.5<z<2.8 as revealed by HST/NICMOS imaging and Infrared Spectrograph mid-infrared...
  • Globular clusters of M60 with HST

    We present g and z photometry and size estimates for globular clusters (GCs) in the massive Virgo elliptical NGC 4649 (M60) using a five-pointing Hubble Space Telescope/Advanced...
  • Spectroscopic properties of BOSS compact galaxies

    Massive compact systems at 0.2<z<0.6 are the missing link between the predominantly compact population of massive quiescent galaxies at high redshift and their analogs and...
  • ALMA 106GHz continuum observations in Chamaeleon I

    We present an Atacama Large Millimeter/submillimeter Array (ALMA) 106 GHz (Band 3) continuum survey of the complete population of dense cores in the Chamaeleon I molecular...
  • "X-shaped" radio sources. II. Sample properties

    In an earlier paper, we presented Jansky Very Large Array multi-frequency, multi-array continuum imaging of a unique sample of low-axial ratio radio galaxies. In this paper, the...
  • "X-shaped" radio sources. I. VLA imaging

    We present archival and Jansky Very Large Array multi-frequency multi-array radio continuum imaging of a unique sample of 100 radio sources that have been selected to be...
  • SDSS, WISE and HI data of local spiral galaxies

    The emerging light from a galaxy is under the influence of its own interstellar medium, as well as its spatial orientation. Considering a sample of 2239 local spiral galaxies in...
  • Centaurus Cluster catalog

    We present a catalog of all galaxies with V<=22.0 and R_iso_>3" within a 0.83deg^2^ region centered on the Centaurus Cluster (Abell 3526) at RA=12h48m, DE=-41{deg}18'....
  • MOJAVE. III. VLA 1.4GHz images

    The MOJAVE blazar sample consists of the 133 brightest, most compact radio-loud AGNs in the northern sky, and it is selected on the basis of VLBA 2cm correlated flux density...
