penquins enables programmatic querying of the Kowalski multi-survey data archive and alert broker, which primarily serves alerts from the Zwicky Transient Facility. It provides a programmatic interface to submit queries, retrieve alert data and associated metadata from Kowalski’s backend, and integrate those queries into automated analysis workflows. The library is intended to streamline access to brokered time‑domain data for downstream scientific analysis.

The Bayesian-based Gaussian Process model AsteroGaP (Asteroid Gaussian Processes) fits sparsely-sampled asteroid light curves. By utilizing a more flexible Gaussian Process framework for modeling asteroid light curves, it is able to represent light curves in a periodic but non-sinusoidal manner.
