Clusters of galaxies are pervaded by plasma which is hot, tenuous, magnetized, and host to a population of relativistic cosmic rays. The cooling time of this gas can be estimated from its observed radiative output, and found to be much shorter than...

I will present recent work with Hairer, Rosati and Yi establishing quantitative lower bounds for the top Lyapunov exponent of linear PDEs driven by two-dimensional stochastic Navier-Stokes equations on the torus. For both the advection-diffusion...

The identity of dark matter is one of the biggest outstanding questions in astrophysics today. The smallest galaxies in the universe, dwarf galaxies, are powerful probes of its identity, as they are composed predominantly of dark matter.  However...

It is a classical fact that countable groups of homeomorphisms of the interval and the circle are characterized by purely algebraic properties, namely linear and circular orderability. It remains a difficult and deep problem to understand countable...

We will discuss combinatorial and algebraic aspects of regular Hessenberg varieties, a large class of subvarieties of the flag variety G/B. For the special case of Peterson varieties, we show their equivariant structure constants are non-negative...
