Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Ana Glidden, Alexander I. Shapiro, Sara Seager +19

Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of sp…

Connecting Granulation and Magnetic Activity in Radial Velocities: The Next Breakthrough for High-Precision Spectroscopy

Ancy Anna John, Khaled Al Moulla, Federica Rescigno +5

Stellar variability has become the dominant limitation to achieving the radial velocity (RV) precision required for the detection and characterization of Earth-like exoplanets. Whi…

Flux-tunable global and local superconductivity in a topological insulator nano-SQUID

Ella Nikodem, Jakob Schluck, Michał Papaj +5

Topological systems are defined by global properties that enforce the existence of local boundary modes. Three-dimensional topological insulators (TIs) were among the earliest prop…

JWST PRIMER: Post-starburst galaxies dominate the low-mass quiescent galaxy population since z~2

Thomas de Lisle, David T. Maltby, Omar Almaini +10

We present the evolution of the stellar mass functions for photometrically selected star-forming, passive and post-starburst galaxies, based on JWST PRIMER observations of the Ultr…

The Fe I 4377 Å Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis

Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21

Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…

Beyond the Fundamental Metallicity Relation: galaxy sizes encode the link between inflow and metallicity

N. F. Boardman, V. Wild, D. Scholte +3

Gas-phase chemical abundances are key observable consequences of galaxy evolution, being intrinsically tied to galaxy formation histories. Gas metallicity rises with increasing ste…
