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