What does the radio sky look like at millisecond rates? --- Radio waves are a great way to study pulsing neutron stars, exoplanets, and other energetic, exotic phenomena. I am interested in studying these objects using radio interferometers, like the Very Large Array and LOFAR. Neutron star pulses can help understand the neutron star life cycle or detect pulses in other galaxies to probe the intergalactic medium.
How is the magnetic field organized in a galaxy? --- The propagation of polarized light encodes information about the magnetized plasma along its path. The recent development of algorithms to study wide-bandwidth, multi-channel spectra has given us new access to this information. I am interested in using this technique to study magnetic fields in galaxies throughout the universe.
Is the Galactic Center host to a massive outflow? --- The Galactic center is the most active and complex region in the Milky Way. A focus of my work is on a shell-like structure that rises about 150 parsecs above the Galactic plane, spanning the central parsecs, known as the Galactic center lobe. I have used multiwavelength observations to show that it is a minor outflow powered by stellar winds and supernovae in our Galactic nucleus.
