Evidence for cloud-to-cloud variations in the ratio of polarized thermal dust emission to starlight polarization

Astronomy & Astrophysics
The correlation between optical starlight polarization and polarized thermal dust emission can be used to infer intrinsic dust properties. This correlation is quantified by the ratio RP/p, which has been measured by the Planck Collaboration to be 5.42 ...

Demo 24-06 Polarization by Double Reflection

, 2001
Polarization of light is obtained by using two reflections from dielectric plates, as in Figure 1. This demonstration illustrates the effect of double reflection on the polarization of an initially unpolarized light beam.

Interstellar Polarization Survey. IV. Characterizing the Magnetic Field Strength and Turbulent Dispersion Using Optical Starlight Polarization in the Diffuse Interstellar Medium

The Astronomical Journal
Angular dispersion functions are typically used to estimate the fluctuations in polarization angle around the mean magnetic field orientation in dense regions, such as molecular clouds.

Demo 24-05 Polarization by Reflection

, 2001
Light waves can be polarized by reflection from a dielectric surface, as shown in Figure 1. The amount of polarization depends on the angle at which the light strikes the surface, with the maximum effect occurring at an angle called the Brewster angle,

A 3D Model of the Local Bubble’s Magnetic Field: Insights from Dust and Starlight Polarization

The Astrophysical Journal
Clustered stellar feedback creates expanding voids in the magnetized interstellar medium known as superbubbles. Although theory suggests that superbubble expansion is influenced by interstellar magnetic fields, direct observational data on 3D superbubble
