Jet Precession in Gamma-Ray Bursts

open access: yesUniverse
Jet precession is thought to be a ubiquitous phenomenon in astronomical events of various scales, including gamma-ray bursts (GRBs). If GRB jets undergo precession, periodic features might be introduced into their light curves.

Coupling a Neural Network-Based forward Model and a Bayesian Inversion Approach to Retrieve Wind Field from Spaceborne Polarimetric Radiometers

open access: yesSensors, 2008
A simulation study to assess the potentiality of sea surface wind vector estimation based on the approximation of the forward model through Neural Networks and on the Bayesian theory of parameter estimation is presented.

A new method for precision cold neutron polarimetry using a He-3 spin filter

open access: yes, 2005
We present a new method for precision measurement of the capture flux polarization of a polychromatic ( white), continuous cold neutron beam, polarized by a He-3 spin filter. This method allows an in situ measurement and does not require knowledge of the

Gamma-ray polarimetry [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003
An astrophysics application of a low noise Double-sided Silicon Strip Detector (DSSD) is described. A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gamma-ray universe in the 0.1-20 MeV energy band. Excellent energy resolution and polarization sensitivity are key features of the SMCT.

Radar polarimetry [PDF]

open access: yes, 2004
Radar polarimetry is a recent development seeing active research only in the last few decades. The phenomenon that optimal (maximal power) reflected fields exist in both the co-polarized and cross polarized channels of the receiving radar antenna was ...

HIGH ENERGY HADRON POLARIMETRY. [PDF]

open access: yes, 2007
Proton polarimetry at RHIC uses the interference of electromagnetic (EM) and hadronic scattering amplitudes. The EM spin-flip amplitude for protons is responsible for the proton's anomalous magnetic moment, and is large. This then generates a significant
