Dark matter, Angles, and the Newtonian limit
I will give brief/simple introductions to three disparate research topics: 1. Using generalised dark matter to put model-independent constraints on the properties of dark matter. 2. Characterising ground-based CMB scans in terms of their "crossing angles" in each pixel, and how this relates to systematics. 3. The large and small scale (Newtonian) limits of gravity in cosmology, and how to describe modified gravity on all scales in a model-independent way. Along the way we will apparently rule out LCDM at more than 4 sigma, learn why it is useful to turn a telescope upside down, and discuss the elephant in Euclid's room.
