I am part of the CMB research group at the Jodrell Bank Centre for Astrophysics and am interested in the CMB Foregrounds. In particular I am interested in Galactic dust as a CMB foreground. Galactic dust is very interesting to study, and recent results provide evidence that the Galactic dust emits not only at infrared (IR) wavelengths, but also at much longer wavelengths in the microwave/radio regime. This anomalous emission is attributed to the very small Galactic dust grains spinning rapidly, emitting electric dipole radiation, and is dominant at ~10 - 60 GHz.

I wrote a Literature Review summarising the history of the anomalous emission from it's first detection in 1996. (A copy of my Lterature Review can be found here).

To try and improve our understanding of the physical nature of the anomalous emission, I am currently studying the Perseus Molecular Cloud, using data from both the Very Small Array (VSA) and the Spitzer Space Telescope.
