  • Catalog of Star-Forming Regions in the Galaxy

    This Catalog of Star-Forming Regions in the Galaxy contains coordinates and fluxes of young objects in the radio and infrared, as well as data on the radial velocities of...
  • Distances to nine dark globules

    Distances to nine dark globules are determined by a method using optical (VRI) and near-infrared (near-IR) (JHK) photometry of stars projected towards the field containing the...
  • Globulettes in four HII regions

    Some HII regions surrounding young stellar clusters contain tiny dusty clouds, which on photos look like dark spots or teardrops against a background of nebular emission. From...
  • BVRI photometry in dark globules

    Using a CCD detector, BVRI photometry has been carried out in the vicinity of nine Lynds dark nebulae. In conjunction with spectroscopic data which could be obtained at a later...
  • Globules and pillars in Cygnus X

    IRAS 20319+3958 in Cygnus X South is a rare example of a free-floating globule (mass ~240M_{sun}_, length ~1.5pc) with an internal HII region created by the stellar feedback of...
  • The Bok globule CB 26

    Planetary cores are thought to form in proto-planetary disks via the growth of dusty solid material. However, it is unclear how early this process begins. We study the physical...
  • UBVRI images of Barnard 207

    Barnard 207 (B207, LDN 1489, LBN 777), also known as the Vulture Head nebula, is a cometary globule in the Taurus-Auriga-Perseus Molecular Cloud region. B207 is known to host a...
  • Rosette Nebula globules

    The Rosette nebula is an HII region ionized mainly by the stellar cluster NGC 2244. Elephant trunks, globules, and globulettes are seen at the interface where the HII region and...
  • YSO candidates in IRAS 20319+3958

    Globules and pillars, impressively revealed by the Spitzer and Herschel satellites, for example, are pervasive features found in regions of massive star formation. Studying...
  • Globulettes in the Carina nebula

    Small molecular cloudlets are abundant in many HII regions surrounding newborn stellar clusters. In optical images these so-called globulettes appear as dark silhouettes against...
  • MAMBO Mapping of c2d Clouds and Cores

    We present maps from our MAMBO 1.2mm wavelength dust emission survey of nearby (<500pc) dense starless and star-forming cores. This data was collected to study evolutionary...
  • Rosette globulettes and shells in the IR

    The compressed molecular shells around the central clusters in HII regions break up into morphologically distinct fragments due to the UV light from the central OB stars. Tiny,...
  • NIR observations of CG1 and CG2

    Cometary globules CG1 and CG2 are "classical" cometary globules in the Gum Nebula region at a distance of ~300pc. The objective of this study is to examine the mass distribution...
  • Near infrared imaging of cometary globule CG12

    Cometary globule 12 is a relatively little investigated medium- and low mass star forming region 210pc above the Galactic plane. This study sets out to discover the possibly...
  • X-ray observations of CG 12

    The mysterious high Galactic latitude cometary globule CG 12 has been observed with the ACIS detector on board the Chandra X-Ray Observatory. We detect 128 X-ray sources, of...
  • 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))...
  • Starless cores in HCN(J=1-0)

    We have carried out a survey toward the central regions of 85 starless cores in HCN(J=1-0) to study inward motions in the cores. Sixty-four cores were detected with HCN lines....
  • DCld303-14.8 & Thumbprint Nebula JHKs phot.

    We present a study of radial density structure of the star forming globule, DCld303.8-14.2 (DC303), and a non-star forming globule, Thumbprint Nebula (TPN), using near-infrared...
