360-degree videos are unique movies that are rendered all around you. No matter where you look - in front, behind, left, right, up, or down - you are watching the movie, though exactly what you see depends on where you look and when. Investments driven by 360-degree cameras have made these videos as easily shareable as regular movies: via the YouTube webpage on a computer, with the YouTube app on a smartphone, or get the most immersive experience in virtual reality (VR) goggles.

Discovery of an orbiting pulsar in 1974 led to increasingly precise measurements that firmly established the existence of of gravitational radiation in the amount and with the properties first predicted by Albert Einstein. Join Dr. Taylor as he describes the torturous path from a theory published in 1915 to the detection of gravitational waves a hundred years later, with many fascinating developments along the way.

Stellar flares are explosive phenomena which, along with providing a way to probe the magnetic environments of stars, may seriously affect the habitability of planets around them. This is particularly true for M stars (e.g. Proxima Centauri, TRAPPIST-1) which host Earth-sized planets in their close proximity “habitable zone”, yet regularly flare with energies greater than the largest Solar flares. In this talk I will present our study of stellar flares using the 13 second cadence full frame images of the Next Generation Transit Survey (NGTS).

Surface phenomena, such as mass loss, angular momentum loss, and magnetism have a large impact on the evolution of hot, massive stars. One-dimensional stellar evolution models rely on parametric prescriptions to account for such surface effects; however, the evaluation, revision, and a change in currently-used prescriptions has become inevitable. First, the impact of mass loss will be discussed and an experimental wind routine will be introduced.

The Wide Field Infrared Survey Telescope (WFIRST) will be NASA's next flagship mission to follow James Webb. Roughly a quarter of WFIRST's primary mission will be spent conducting an exoplanet microlensing survey. The survey will provide a statistical assay of the cold exoplanet population with masses greater than that of Mars and orbits beyond ~1 AU, with a total planet yield comparable to Kepler's.

Despite observations of thousands of type Ia supernovae (SNe Ia), we still do not have a clear understanding of the progenitor systems of these explosions. Our limited understanding of these events restricts our understanding of the nature of Dark Energy. The most promising path forward is obtaining observations of the SNe Ia within a few days of the explosion. I’ll discuss SN2018oh and other spectroscopically confirmed SNe Ia with exceptionally early-time observations, discovered by the Kepler Extragalactic Survey (KEGS).
