Abstract: Complementing the spectacular breakthroughs in gravitational wave and multi-messenger observations of merging black holes and neutron stars, advancements in our theoretical understanding and modelling of strong gravity are essential to...

Star formation in galaxies are governed by the complex interplay of several nonlinear physical mechanisms operating in the interstellar medium (ISM). However, in spite of the underlying complexity, there is overwhelming evidence for fundamental...

Star-shredding supermassive black holes (Tidal Disruption Events, TDEs) are potential emitters of high energy hadrons and neutrinos. Several TDEs have been observed as coincident with neutrino events detected at the IceCube neutrino observatory. I...

The DAMIC-M experiment will exploit the sub-electron resolution capabilities of skipper charge-coupled devices (CCDs) to search for light dark matter particles in a broad range of masses from 1 eV to 10 GeV. A prototype DAMIC-M detector has been...

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 ...
