Accounting for stellar activity signals in radial-velocity data by using Change Point Detection techniques
U. Simola, A. Bonfanti, X. Dumusque +3
Active regions on the photosphere of a star have been the major obstacle for detecting Earth-like exoplanets using the radial velocity (RV) method. A commonly employed solution for…
Differentiating small-scale subhalo distributions in CDM and WDM models using persistent homology
Jessi Cisewski-Kehe, Brittany Terese Fasy, Wojciech Hellwing +3
The spatial distribution of galaxies at sufficiently small scales will encode information about the identity of the dark matter. We develop a novel description of the halo distribu…
The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
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 precisi…
