The classical Kepler problem and geodesic motion on spaces of constant curvature
Aidan J. Keane, Richard K. Barrett, John F. L. Simmons
In this paper we clarify and generalise previous work by Moser and Belbruno concerning the link between the motions in the classical Kepler problem and geodesic motion on spaces of…
Scattering polarization due to light source anisotropy
R Ignace, M Al-Malki, J Simmons +3
We consider the polarization arising from scattering in an envelope illuminated by a central anisotropic source. Spherical harmonics are used to describe both the light source anis…
The optical polarization of spiral galaxies
J. F. L. Simmons, E. Audit
Scattering of starlight by dust, molecules and electrons in spiral galaxies will produce a modification of the direct intensity and a polarization in the observed light. We treat t…
The kinematic Sunyaev Zeldovich effect and transverse cluster velocities
Edouard Audit, John F. L. Simmons
The polarization of the CMBR scattered by galaxy clusters in the kinematic Sunyaev Zeldovich effect depends on the transverse velocity of the cluster. This polarizing effect is pro…
The use of light polarization for weak-lensing inversions
Edouard Audit, John F. L. Simmons
The measurement of the integrated optical polarization of weakly gravitationally lensed galaxies can provide considerable constraints on lens models. The method outlined depends on…
The Polarisation Signatures of Microlensing
A. M. Newsam, J. F. L. Simmons, M. A. Hendry +1
It has already been shown that microlensing can give rise to a non-zero variable polarisation signal. Here we use realistic simulations to demonstrate the additional information th…
