We are living in a golden era for testing gravitational physics with precision experiments. This talk will present new results using a variety of tests with radio pulsars. These results will be placed in context of other experiments (including LIGO...

The mechanism of the explosion of massive stars remains uncertain. I will discuss aspects of the critical condition for explosion, the observed supernova diversity, and the connection to gamma-ray bursts and super-luminous supernovae. I will focus...

All the magnetized planets in our solar system, including Earth, produce bright emission at low radio frequencies, predominantly originating in high magnetic latitudes and powered by magnetospheric currents. It has long been speculated that similar...

Equilibrium phase-space models have enabled much of what we know about the structure of the Milky Way, including global or bulk properties of Galactic dark matter. Kinematic data from the recent second data release from the Gaia mission has shown...
