The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Lily L. Zhao, Debra A. Fischer, Eric B. Ford, Alex Wise, Michaël Cretignier | Summary: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods […]

Accurate effective fluid approximation for ultralight axions

Posted by klaurent Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, , , | Summary: Ultralight axions are theoretically interesting and phenomenologically rich dark sector candidates, but they are difficult to track across cosmological timescales because of their fast oscillations. We resolve this problem by developing a novel method to evolve them efficiently and […]
