Parker Solar Probe and Solar Orbiter are providing unprecedented joint measurements of the radial evolution of the solar wind from below the Alfven point out to 1 au allowing new empirical constraints on its flow properties. We will show results...

The Bahcall Lunch follows the astrophysics colloquium lecture. 

Astronomers have been predicting and searching for planets beyond Neptune for almost 180 years. In all previous cases the predictions were based on bad data, bad physics, or both, and the predictions turned out to be wrong. In 2016, we joined this ...

While cosmological parameter inference is predominantly Bayesian, in this talk, I will discuss how frequentist statistics can be used as a complementary method for parameter inference. I will introduce the frequentist profile likelihood and discuss...

Abstract: Recently it was shown that black holes impart a fundamental rate of decoherence on all nearby quantum superpositions [Danielson, Satishchandran, Wald (DSW) 2022], eventually erasing all quantum information in their vicinity.  The effect...

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...
