Spitzer and HHT observations of starless cores: masses and environments (2009)
Stutz, Amelia M., Rieke, George H., Bieging, John H., Balog, Zoltan, Heitsch, Fabian, Kang, Miju, ...
We present Spitzer observations of a sample of 12 starless cores selected to have prominent 24 micron shadows. The Spitzer images show 8 and 24 micron shadows and in some cases 70 micron shadows;...
Kang, Miju, Bieging, John H., Povich, Matthew S., Lee, Youngung
We present 737 candidate Young Stellar Objects (YSOs) near the W51 Giant Molecular Cloud (GMC) over an area of 1.25 deg x 1.00 deg selected from Spitzer Space Telescope data. We use spectral energy...
Triggered Star Formation in a Double Shell near W51A (2009)
Kang, Miju, Bieging, John H., Kulesa, Craig A., Lee, Youngung
We present Heinrich Hertz Telescope CO observations of the shell structure near the active star-forming complex W51A to investigate the process of star formation triggered by the expansion of an HII...
The Extended Environment of M17: A Star Formation History (2009)
Povich, Matthew S., Churchwell, Ed, Bieging, John H., Kang, Miju, Whitney, Barbara A., Brogan, Crystal L., ...
M17 is one of the youngest and most massive nearby star-formation regions in the Galaxy. It features a bright H II region erupting as a blister from the side of a giant molecular cloud (GMC)....
Spitzer Observations of L429: A Near-collapse or Collapsing Starless Core (2008)
Stutz, Amelia M., Bourke, Tyler L., Rieke, George H., Bieging, John H., Misselt, Karl A., Myers, Philip C., ...
We present Spitzer infrared observations of the starless core L429. The IR images of this core show an absorption feature, caused by the dense core material, at wavelengths 35 mag near the center....
Stutz, Amelia M., Rubin, Mark, Werner, Michael W., Rieke, George H., Bieging, John H., Keene, Jocelyn, ...
We present infrared and millimeter observations of Barnard 335, the prototypical isolated Bok globule with an embedded protostar. Using Spitzer data we measure the source luminosity accurately; we...

A search for temperature and density variations in NGC 7027 with the Hubble Space Telescope (2008)
Bieging, John H., Boley, Paul A., Latter, William B.
We observed the young planetary nebula NGC 7027 with the HST Imaging Spectrograph (STIS) in long-slit mode at five slit positions along the major axis of the nebula, over the wavelength range from...
Spitzer observations of a 24 micron shadow: Bok Globule CB190 (2007)
Stutz, Amelia M., Bieging, John H., Rieke, George H., Shirley, Yancy L., Balog, Zoltan, Gordon, Karl D., ...
We present Spitzer observations of the dark globule CB190 (L771). We observe a roughly circular 24 micron shadow with a 70 arcsec radius. The extinction profile of this shadow matches the profile...
Biller, Beth A., Close, Laird M., Li, Aigen, Marengo, Massimo, Bieging, John H., Hinz, Phil M., ...
We imaged the symbiotic star CH Cyg and two PSF calibration stars using the unique 6.5m MMT deformable secondary adaptive optics system. Our high-resolution (FWHM=0.3"), very high Strehl (98%+-2%)...
Mid-Infrared Imaging of the Post-AGB Star AC Herculis with the MMT Adaptive Optics System (2003)
Close, Laird M., Biller, Beth, Hoffmann, William F., Hinz, Phil M., Bieging, John H., Wildi, Francois, ...
We utilized the MMT's unique deformable secondary adaptive optics system to produce high-resolution (FWHM=0.3"), very high Strehl mid-infrared (9.8, 11.7 & 18 micron) images of the post-AGB star AC...
Revealing the Photodissociation Region: Hubble Space Telescope/NICMOS Imaging of NGC 7027 (2000)
Latter, William B., Dayal, Aditya, Bieging, John H., Meakin, Casey, Hora, Joseph L., Kelly, Douglas M., ...
We report results from a Hubble Space Telescope (HST) and Near-Infrared Camera and Multiobject Spectrometer (NICMOS) program to study the distribution of hot neutral (molecular hydrogen) and ionized...
