  • Lynds' Catalogue of Bright Nebulae

    The Catalogue of Bright Nebulae lists the galactic and equatorial coordinates of the center of the cloud, the dimensions of the nebulae as measured on the photograph on which it...
  • Catalog of bright diffuse Galactic nebulae

    The Catalog of bright diffuse Galactic nebulae was compiled in the frame of a thesis investigating the spatial distribution and the geometrical properties of bright diffuse...
  • Southern Stars embedded in nebulosity

    A survey of the Milky Way southward of the Palomar Sky Survey for the identification of reflection nebulae was carried out at the Cerro Tololo Inter-American Observatory in...
  • H-{alpha} emission regions in Southern Milky Way

    The Catalogue of Rodgers, Cambell, and Whiteoak (RCW), was the result of a survey of emission nebulae carried out at Mt. Stromlo Observatory from December 1957 to April 1959....
  • UBV and line identification of V1853 Cyg

    Photoelectric and spectroscopic observations of the protoplanetary object V1853 Cyg, a B supergiant with an IR excess, are given. The observations were carried out with a UBV...
  • Spectrum of bipolar nebula AFGL 2688

    Based on echelle spectra obtained at the prime focus of the 6-m telescope, the detailed chemical composition of one of the components of the bipolar nebula identified with the...
  • Extended red emission in IC59 and IC63

    We analysed new wide-field, wide- and narrow-band optical images of IC 59 and IC 63, two nebulae that are externally illuminated by the early B-star {gamma} Cas, with the...
  • Cobalt emission in nebular phase spectra

    The light curves of Type Ia supernovae (SNe Ia) are powered by the radioactive decay of ^56^Ni to ^56^Co at early times, and the decay of ^56^Co to ^56^Fe from ~60 d after...
  • ATCA Survey of Sagittarius B2 at 7mm

    We present a 30-50GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array (ATCA) with 5 - 10 arcsec resolution. We analyze the spectra towards three...
  • MIPS 24um nebulae

    Massive evolved stars lose a large fraction of their mass via copious stellar wind or instant outbursts. During certain evolutionary phases, they can be identified by the...
  • Clusters and associations in SMC and LMC

    We investigate the degree of spatial correlation among extended structures in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). To this purpose, we work with...
  • Catalogue of extended objects in Magellanic Clouds

    We update the Small Magellanic Cloud (SMC), Bridge and Large Magellanic Cloud (LMC) catalogues of extended objects that were constructed by members of our group from 1995 to...
  • JHKs photometry of Hourglass nebula

    A detailed study of the Hourglass nebula in the M8 star-forming region is presented. The study is mainly based on recent subarcsec-resolution JHKs images taken at Las Campanas...
  • ORICAT Catalog of Stars in Orion Great Nebula

    Six Tautenburg 2-m Schmidt telescope plates have been used to derive proper motions for 12740 stars down to Blim=18.5 in the region centered at RA=83.45grad, Dec=-5.20grad of...
  • Stellar groups of Orion's Sword region

    The region of Orion's Sword with coordinates RA=83.79{deg}, DE=-5.20{deg} and a size of 1.0{deg}x2.5{deg} is analyzed. We compiled a master catalog of stars observed in the...
  • Stellar bow shock nebulae spectroscopic obs.

    Arcuate mid-infrared nebulae known as stellar bow shock nebulae (SBNe) have been previously hypothesized to be supported by the strong stellar winds and/or luminosity of massive...
  • Carina OB stars in the CCCP catalog

    The Chandra Carina Complex contains 200 known O- and B-type stars. The Chandra survey detected 68 of the 70 O stars and 61 of 127 known B0-B3 stars. We have assembled a publicly...
  • Classification of CCCP X-ray sources

    The Chandra Carina Complex Project (CCCP) provides a sensitive X-ray survey of a nearby starburst region over >1deg^2^ in extent. Thousands of faint X-ray sources are found,...
  • Chandra Carina Complex Project (CCCP) catalog

    We present a catalog of ~14000 X-ray sources observed by the ACIS instrument on the Chandra X-ray Observatory within a 1.42deg^2^ survey of the Great Nebula in Carina, known as...
  • The NAN complex. II. MIPS observations

    We present observations of ~7deg^2^ of the North American and Pelican Nebulae region at 24, 70, and 160um with the Spitzer Space Telescope Multiband I] ing Photometer for...
