  • Nebulae in the Magellanic Clouds

    Long exposures of the complexes of ionized hydrogen in both the LMC and SMC have been taken with the 48-in. SRC Schmidt camera through an H{alpha}+[N II] interference filter to...
  • Dark Nebulae and Globules for l=240-360deg

    (adapted from Anne C. Raugh, NASA STI-T-1-5810-508-86) The catalog is a compilation of data gleened from a study of the European Southern Observatory Quick Blue Survey (ESO(b))...
  • Lynds' Catalogue of Dark Nebulae (LDN)

    This catalog is an updated version from the published version. The catalog was based on the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The...
  • 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...
  • Parenago Catalog of Stars in Orion Nebula

    The present catalogue is a machine-readable version of the catalogue of stars in the area of the Orion nebula, published by P.P. Parenago (1954). The sky area between 5h 24m and...
  • IR sources in Magellanic Clouds

    The authors have used the IRAS data to construct maps of the Magellanic Clouds at wavelengths of 12, 25, 60, and 100 microns. These are contained in the published volume only....
  • CO(2-1) maps of IRAS 18059-3211

    We study the nature of Gomez's Hamburger (IRAS 18059-3211), a nebula that has been proposed to be a post-AGB object. Such a classification has not been confirmed; instead, we...
  • Infrared nebulae around young stellar objects

    We present a K-band atlas of 106 reflection nebulae, 41 of which are new discoveries. We observed these nebulae with the University of Hawaii 2.2m telescope in the course of an...
  • 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...
  • Einstein survey of the Orion nebula region

    We have analyzed archival Einstein Observatory images of a roughly 4.5 square degree region centered on the Orion Nebula. In all, 245 distinct X-ray sources have been detected...
  • ROSAT survey of the Orion nebula region

    We present results from three deep ROSAT high-resolution imager observations of the Orion Nebula star-forming region. The X-ray images contain over 1500 catalogued stars in a...
  • 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...
