Fundamental and beyond-standard-model physics from CMB-electron scattering


As the CMB travels through the Universe, it interacts with large-scale structure, including with the inhomogeneous electron gas that surrounds galaxies. The Compton-scattering of the CMB off these electrons leads to the Sunyaev--Zel'dovich effect. This induces new CMB anisotropies, which carry information about the distribution of electrons, and gives us access to a new cosmological probe: their large-scale velocity. We can access this information with state-of-the-art high-resolution CMB surveys such as ACT and SO. I will talk about how the SZ effect in combination with a galaxy survey will constrain fundamental and beyond-standard-model physics, focusing on probes of inflation.  I will also talk about more exotic CMB-electron interactions and recent constraints on beyond-standard-model particle physics, focusing on dark photon-CMB and axion-CMB interactions.

Wednesday 22nd October at 11am, A113 CAPT – CAPT Coding Club



Wednesday 22nd October at 3.45pm, C4 Physics – Astronomy Weekly Seminar

Tim Pearce (Warwick)

Extrasolar Kuiper Belts



Our Solar System contains not only planets, but also many smaller bodies, like asteroids and comets. These bodies are collectively called 'debris', and they tend to be concentrated in 'debris discs' like the Asteroid Belt and Kuiper Belt. We can image extrasolar Kuiper Belts around other stars too, and these belts exhibit a broad diversity of shapes and features. These shapes are often attributed to interactions with unseen exoplanets. In this talk I give a broad overview of debris discs, including observations, dynamics and evolution. I also explain what debris discs teach us about exoplanets and their historical evolution, and outline what the biggest outstanding questions are. For this talk I assume no prior knowledge and try to make it accessible to a wide range of seniorities and experience levels.
