Were All Massive Stars Born in OB Associations and Clusters?
You-Hua Chu, Robert A. Gruendl
It has been commonly conjectured that all massive >10 Msun stars are born in OB associations or clusters. Many O and B stars in the Galaxy or the Magellanic Clouds appear to exist…
Far-infrared polarimetry from the Stratospheric Observatory for Infrared Astronomy
J. E. Vaillancourt, D. T. Chuss, R. M. Crutcher +8
Multi-wavelength imaging polarimetry at far-infrared wavelengths has proven to be an excellent tool for studying the physical properties of dust, molecular clouds, and magnetic fie…
Hard X-ray and Infrared Emission from Apparently Single White Dwarfs
Y. -H. Chu, R. A. Gruendl, M. A. Guerrero +1
The photospheric emission of a white dwarf (WD) is not expected to be detectable in hard X-rays or the mid-IR. Hard X-ray (~1 keV) emission associated with a WD is usually attribut…
Cyber-infrastructure to Support Science and Data Management for the Dark Energy Survey
C. Ngeow, J. J. Mohr, T. Alam +9
The Dark Energy Survey (DES; operations 2009-2015) will address the nature of dark energy using four independent and complementary techniques: (1) a galaxy cluster survey over 4000…
Imaging and Spectroscopy of the Planetary Nebula NGC 6778
Vicente Maestro, Martin A. Guerrero, Luis F. Miranda
We present narrow-band images and long-slit echelle spectra of the planetary nebula (PN) NGC 6778. The data show this PN as bipolar, with a very prominent low-excitation equatorial…
Multiple Point-Symmetric Ejections in IC 4634
Martin A. Guerrero, Luis F. Miranda, You-Hua Chu
We present a spatio-kinematical study of the planetary nebula (PN) IC 4634 which has experienced several episodes of point-symmetric ejections oriented at different directions. The…
