Low Polarization Standards
(Astronomical Society of the Pacific, 2007)
There is renewed interest in high sensitivity polarimetry as a means of observing the polarization signal of extra-solar planets. We describe the measurement of low polarized standards at fractional polarizations of parts ...
Polarimetry : a powerful diagnostic tool in astronomy
(2006)
Knowledge of the polarization state of radiation provides far more astrophysical information than intensity alone. Polarimetry has played a key role in the development of modern astronomy, providing insight into physical ...
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. ...
