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 …
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) …
