An Extended Search for Circularly Polarized Infrared Radiation from the OMC-1 Region of Orion
(2005-05)
We present new observations of circular polarization (CP) at 2.2 m in the Orion (OMC-1) molecular cloud. Our results extend a previously published study of the region.We show that the degree of CP correlates spatially with ...
UV Circular Polarisation in Star Formation Regions : The Origin of Homochirality?
(2005-02)
Ultraviolet circularly polarised light has been suggested as the initial cause of the homochirality of organic molecules in terrestrial organisms, via enantiomeric selection of prebiotic molecules by asymmetric photolysis. ...
Polarimetry Techniques at Optical and Infrared Wavelengths
(Astronomical Society of the Pacific, 2005)
The techniques and components used to measure both linear and circular polarization at wavelengths from 0.3 ¹m to 20 ¹m are reviewed. Some emphasis is given to the implementation of polarimetry on the latest generation of ...
CanariCam-Polarimetry: A Dual-Beam 10 m Polarimeter for the GTC
(Astronomical Society of the Pacific, 2005)
The advent of large (¸8m) telescopes, along with the new breed of mid-IR instrumentation, has opened a new window to di®raction-limited polarimetry. CanariCam, nearing completion at the University of Florida for the 10m ...
Spectropolarimetry of the 3.4 m Band in the Quintuplet
(Astronomical Society of the Pacific, 2005)
We present spectropolarimetry of the 3.4?m solid hydrocarbon absorption feature arising in the ISM toward the Quintuplet member GCS3-II, permitting for the first time a comparison of the hydrocarbon and silicate polarizations ...
Simultaneous Optical and Near-Infrared Spectropolarimetry of Type 2 Seyfert Galaxies with TRISPEC
(Astronomical Society of the Pacific, 2005)
We present 0.46{2.5 ¹m spectropolarimetry of four type 2 Seyfert nuclei, Mrk 463E, Mrk 1210, NGC 1068, and NGC 4388, obtained with TRISPEC (Triple Range Imager and SPECtrograph) at UKIRT. The polarizations from dust or ...
Opportunities for Imaging and Spectro-Polarimetry at UKIRT
(Astronomical Society of the Pacific, 2005)
Near-IR imaging and spectro-polarimetry are offered with the facility instruments UIST and UFTI. Both linear and circular polarimetry are possible, the former from 1-5¹m, the latter from 1-2.5¹m. The IRPOL polarimetry ...
Infrared Polarimetry of Interstellar Dust
(2005)
Grains in the diffuse interstellar medium, and in at least some parts of dense molecular clouds, are aligned with their short axis preferentially along the direction of the local magnetic field. At longer infrared wavelengths ...
