BFMTrack: Latent Sequence Optimization for Physics-Based Motion Tracking with Behavioral Foundation Models

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Behavioral Foundation Models (BFMs) offer a promising path toward universal physics-based character control by organizing a rich repertoire of physically plausible behaviors into a latent space, guided by a large-scale motion dataset. While these models excel at time-invariant tasks, such as goal-reaching and state-based reward optimization, their latent space does […]

Measuring Magnetic Fields Near and Far with the SKA via the Zeeman Effect

Posted by klaurent Stanford

Kavli Affiliate: Susan Clark | Summary:Zeeman splitting in spectral lines — both in emission and absorption — provides direct estimates of magnetic field strength and direction in magnetized gas in our own Milky Way and in external galaxies. We discuss the potential for using the Square Kilometre Array (SKA) to measure the Zeeman effect in […]

Coupled atmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling — Primordial Magma Oceans of Earth and Venus

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | Summary:Earth and Venus represent two evolutionary outcomes arising from initially molten ‘magma ocean’ periods, followed by lifetimes of chemical and geophysical divergence. Their physics is common to all rocky planets and is accessible to simulations that adopt coupled interior-atmosphere modelling approaches. Our understanding of planet histories and interpretation of current […]

Kepler Image-Subtracted Light Curves and Variable Star Catalog of NGC 6819

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | Summary:Variable stars in open clusters are valuable probes of stellar evolution. They provide precise measurements of stellar properties, constrain cluster ages and distances, and trace the angular momentum evolution of stellar populations. To advance these studies, we applied image subtraction and systematic reduction techniques to the NGC 6819 Kepler superstamp […]
