nbi: the Astronomer's Package for Neural Posterior Estimation
Keming Zhang, Joshua S. Bloom, Stéfan van der Walt +1
Despite the promise of Neural Posterior Estimation (NPE) methods in astronomy, the adaptation of NPE into the routine inference workflow has been slow. We identify three critical i…
HEALPix Alchemy: Fast All-Sky Geometry and Image Arithmetic in a Relational Database for Multimessenger Astronomy Brokers
Leo P. Singer, B. Parazin, Michael W. Coughlin +4
Efficient searches for electromagnetic counterparts to gravitational wave, high-energy neutrino, and gamma-ray burst events demand rapid processing of image arithmetic and geometry…
Phenomenological classification of the Zwicky Transient Facility astronomical event alerts
Dmitry A. Duev, Stéfan J. van der Walt
The Zwicky Transient Facility (ZTF), a state-of-the-art optical robotic sky survey, registers on the order of a million transient events - such as supernova explosions, changes in…
A recurrent neural network for classification of unevenly sampled variable stars
Brett Naul, Joshua S. Bloom, Fernando Pérez +1
Astronomical surveys of celestial sources produce streams of noisy time series measuring flux versus time ("light curves"). Unlike in many other physical domains, however, large (a…
