Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, Logan Riggs, Max Tegmark, , | Summary: Sparse autoencoders (SAEs) are a promising technique for decomposing language model activations into interpretable linear features. However, current SAEs fall short of completely explaining model performance, resulting in "dark matter": unexplained variance in activations. This work investigates dark […]

Kavli Affiliate: Nathan P. Lourie | First 5 Authors: Geoffrey Mo, Kishalay De, Eli Wiston, Nayana A. J., Raffaella Margutti | Summary: Type Ia supernovae arise from the thermonuclear explosions of white dwarfs in multiple star systems. A rare sub-class of SNe Ia exhibit signatures of interaction with circumstellar material (CSM), allowing for direct constraints […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Qier An, Chelsea X. Huang, Timothy D. Brandt, Robert A. Wittenmyer | Summary: As exoplanet surveys reach ever-higher sensitivities and durations, planets analogous to the solar system giant planets are increasingly within reach. HD 28185 is a Sun-like star known to host a $msin i=6 […]
Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Saverio Cambioni, Sara Seager, , | Summary: Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories – metal-rich formation hypothesis and naked core hypothesis – that explain how formation and evolution can alter the compositions and […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano, Eduardo J. S. Villaseñor, | Summary: The relation between the Husain-Kuchav{r} model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to the Hamiltonian dynamics of […]
