The TESS-Keck Survey IV: A Retrograde, Polar Orbit for the Ultra-Low-Density, Hot Super-Neptune WASP-107b

We measured the Rossiter–McLaughlin effect of WASP-107b during a single transit with Keck/HIRES. We found the sky-projected inclination of WASP-107b’s orbit, relative to its host star’s rotation axis, to be $|\lambda| = 118^{+38}_{-19}$ degrees. This …

Using machine learning to classify galaxy spectra as containing a type Ia supernova or not.

RR Lyrae stars in M15

Observations of variable stars in the globular cluster M15 to measure its distance.

Limits on the Emission of Gamma Rays From M31 (The Andromeda Galaxy) With HAWC

The detection of the Fermi Bubbles suggests that spiral galaxies such as the Milky Way can undergo active periods. Using gamma-ray observations, we can investigate the possibility that such structures are present in other nearby galaxies. We have …

Searching for TeV Gamma-ray Emission from Binary Systems with HAWC

Compact binary systems can provide us with unique information on astroparticle acceleration and cosmic ray production. However, only five binary systems have ever been observed in TeV $\gamma$-rays. The High Altitude Water Cherenkov (HAWC) …
