Astrophysics

The search for life in the Universe is frustrated by a single known example, ourselves - a data point loaded with selection bias. In such a data starved regime, priors have an outsized role and it's tempting to throw our arms in the air in despair...

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...

Astrophysical black holes are surrounded by accretion disks, jets, magnetospheres, and coronae consisting of magnetized relativistic plasma. They produce observable multi wavelength and multi messenger signals from near the event horizon and it is...

The interplay between memorization and generalization in pattern recognition lies at the core of modern artificial intelligence. This tension becomes particularly pronounced as we train models with billions or even trillions of parameters—models...

Abstract: In AdS/CFT, a spacetime geometry is said to contain a python's lunch when there exist choices of boundary regions with associated entanglement wedges that contain locally but not globally minimal surfaces. Previously, such geometries have...

Abstract: The self-confinement picture of cosmic-ray transport often hinges on the linear theory of growth and damping of magnetic perturbations. Especially the balance between the growth of the resonant streaming instability and non-linear Landau...
