We present our results from the Southern Galactic Plane Survey, an effort to map the fourth quadrant of the Milky Way in linear polarization at a frequency of 1.4 GHz and at a resolution of 1–2 arcmin. These data are a powerful probe of both the turbulence and large-scale structure of magneto-ionic gas, and have revealed a variety of new features in the interstellar medium.

In the present work it is shown that in atomic photoionization the Fanolike behaviour of vector correlation parameters in the region of an isolated autoionizing resonance possesses two universal values: the width and the energy shift with respect to the energy of the autoionizing state. This property is confirmed by fluorescence polarimetry studies, which provide, in the particular case of Xe 4...

Polarimetry of Gamma-Ray Burst (GRB) afterglows in the last few years has been considered one of the most effective tool to probe the geometry, energetic, dynamics and the environment of GRBs. We report some of the most recent results and discuss their implications and future perspectives.

We propose a model, based on a quantum stochastic differential equation QSDE , to describe the scattering of polarized laser light by an atomic gas. The gauge terms in the QSDE account for the direct scattering of the laser light into different field channels. Once the model has been set, we can rigorously derive quantum filtering equations for balanced polarimetry and homodyne detection experi...

A compact polarimetry (CP) mode can be defined as a dual-pol mode that transmits a generic polarized wave, usually circular or linear oriented at 45 deg. In this paper, we first show some observations of the reconstruction algorithms of pseudo full PolSAR/PolInSAR information from CP data. Secondly, we discuss the impact of the SAR processor and receiver on the CP simulated data.

The growth of horizontal nanowires (NWs) guided by epitaxial and graphoepitaxial relations with the substrate is becoming increasingly attractive owing to the possibility of controlling their position, direction, and crystallographic orientation. In guided NWs, as opposed to the extensively characterized vertically grown NWs, there is an increasing need for understanding the relation between st...

We present 850 μm imaging polarimetry of two high-mass star forming regions – W48 and S152. Within these regions we have identified two candidate high-mass protostellar objects – W48W and S152SE. The submillimetre continuum emission from the candidate HMPOs is bright in comparison to the nearby H  regions. W48W is a cold dense source, with no radio or mid-infrared emission. S152SE has an IRAS...

Scientific evidence accumulated over the last decade indicates that weather radar polarimetry has passed two important tests. First, as suggested by theory, polarimetric signals contain significant information about hydrometeor habits; and second, the information can be retrieved with sufficient accuracy to be useful. If it passes the cost effectiveness test, the technique should be adopted for...
