A Polarization Flare in 3C 273: A Clue to Jet Physics
(Astronomical Society of the Pacific, 2001)
We present UBVRIJHK polarization and flux density observations of the quasar 3C 273 obtained during a time of outburst over two weeks in 1988 February. We have modelled these data with two power law components, each with ...
Constraints on the nuclear emission of the Circinus galaxy : optical and near-IR spectropolarimetry
(2000)
We present optical and, for the first time, K-band spectropolarimetry of the nuclear region of the Circinus galaxy. In the optical we confirm the previous discovery of polarized broad Hα. We have not detected polarized ...
High Circular Polarization in the Star Forming Region NGC 6334: Implications
(Astronomical Society of the Pacific, 2000)
The amino-acids which form the building blocks of biological proteins are all left-handed molecules. By contrast, when these molecules are made in the laboratory equal numbers of the right and left-handed versions are made. ...
