In this talk, we will consider a stabilized version of the fundamental existence problem of symplectic structures (cf. Open Problem 1 in McDuff & Salamon). Given a formal symplectic manifold, i.e. a closed manifold $M$ with a non-degenerate 2-form...

Supermassive black holes' (SMBHs) feeding and feedback cycles play a vital role in galaxy formation and evolution. While current state-of-the-art numerical simulations can successfully reproduce the multiphase gas at the galaxy-scale, it is not well...

I present the evolution of the relationship between galaxy stellar mass and their host dark matter halo mass since the Universe was only about a billion years old (z ~ 5) until today. The galaxy-halo mass relationship was constrained through the...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

I will discuss a recent proof of new cases of the Hilbert-Smith conjecture for actions by homeomorphisms of symplectic nature. In particular, it rules out faithful actions of the additive $p$-adic group in this setting and provides further...
