</b></span><span style="font-family: "Segoe UI", "Segoe UI Web (West European)", -apple-system, "system-ui", Roboto, "Helvetica Neue", sans-serif; font-size: 15px; color: rgb(0, 0, 0);"> 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.<br>
