Hierarchical Bayesian power-law fits to early ZTF light curves of 972 SNe Ia yield population parameters for rise time, index, and color evolution, revealing a bifurcation with SALT2 stretch.
A hierarchical Bayesian approach with multivariate Gaussian population prior reduces bias in demographic inference of SN Ia power-law rise parameters compared to individual fitting.
The DECam Shadow Survey has detected variable LBV eruptions in AT2017des with peaks brightening by ~0.05 mag per year, reaching luminosities similar to extreme SN impostors.
