Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters
Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12
Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…

3D insights into SN 1987A: ALMA observations compared to hydrodynamical explosion simulations
R. Wesson, M. Gabler, M. Lyons +9
We obtain three-dimensional distributions of CO and SiO molecules from high spatial resolution (0.03--0.06") ALMA observations of SN 1987A at two different epochs. The evolution be…

The New Science of Unidentified Aerospace-Undersea Phenomena (UAP)
Kevin H. Knuth, Philippe Ailleris, Hussein Ali Agrama +36
After decades of dismissal and secrecy, it has become clear that a significant number of the world's governments take Unidentified Aerospace-Undersea Phenomena (UAP), formerly know…
