Key Extragalactic Programmes
Mid-IR Polarimetry
- An almost virgin field.
- Search for Faraday rotation in AGNs.
- The radio/visible breakpoint for polarisation angle and degree (where do we cease to see the radio jet?).
- Spectroscopy and spectropolarimetry of the 10?m silicate ice feature to probe the torus.
- Direction and strength of B-field in star formation regions (how does it influence star formation?)
? Little done to date. Many opportunities.
