The magnetic field structure of the DR21 region
(1999)
We present results of imaging polarimetry of the H2 v=1--0 S(1) line towards the outflow lobes of DR21. The polarization vectors are produced by dichroic absorption in a medium of aligned grains and therefore delineate the ...
Polarimetry for the Gemini telescopes
(1998)
Polarimeters at optical and near-IR wavelengths are increasingly available as part of facility instruments at major observatories, and are used for a large number of astronomical programs, ranging form nearby star-forming ...
Circular Polarization in Star- Formation Regions : Implications for Biomolecular Homochirality
(1998)
Strong infrared circular polarization resulting from dust scattering in reflection nebulae in the Orion OMC-1 star-formation region has been observed. Circular polarization at shorter wavelengths might have been important ...
Polarimetry for the Gemini telescopes
(Int Soc for Optical Engineering, 1998)
Polarimeters at optical and near-IR wavelengths are increasingly available as part of facility instruments at major observatories, and are used for a large number of astronomical programs, ranging form nearby star-forming ...
Identification of the exciting source of Herbig-Haro objects 135 and 136
(1997)
We have identified the exciting source of the Herbig-Haro objects HH135 and 136 by near-infrared polarimetric imaging of the associated extensive reflection nebula. The source is situated at the middle of the two Herbig-Haro ...
3 MU M Spectropolarimetry of 1120 Ice in Young Stellar Objects
(Astronomical Society of the Pacific, 1996)
Spectropolarimetry of the water-ice feature at 3.1um towards a number of YSOs is presented. The data show that excesses of polarization and changes in position angle across the feature are common. The polarization excess ...
Modeling New Spectropolarimetry Data for the BN Object
(Astronomical Society of the Pacific, 1996)
New spectropolarimetry data taken for the BN object include many previously unobserved features. Among these are a possible polarization reversal at the short wavelength end of the ice feature and a rotation in the position ...
Magnetic Fields in Star Forming Regions - Near-Infrared and Submillimeter Approaches
(Astronomical Society of the Pacific, 1996)
In order to study the magnetic field structure in star forming regions on various scales, we have been conducting both near-infrared and submillimeter polarimetry toward nearby molecular clouds. The near-infrared approach ...
Near-infrared and millimetre polarimetry of CEN A
(1996)
We present near-infrared polarization images of the nuclear region of CenA, and millimetre polarimetry of the nucleus. In the near-infrared the polarization vectors mainly lie along the dust lane, with the polarization ...
High Resolution Studies of Molecular Hydrogen by Means of Near-Infrared Fabry-Perot Imaging
(Astronomical Society of the Pacific, 1995)
We present a study of the velocity profiles of the v=1-0 S(1) transition of molecular hydrogen (H2) towards the star forming region of OMC-1. A three dimensional data cube is presented which displays the spatial distribution ...
