Neural Simulation-based Inference with Hierarchical Priors for Detached Eclipsing Binaries
Jacqueline Blaum Hough, Joshua S. Bloom
Detached eclipsing binaries (DEBs) enable direct inference of stellar and orbital properties across diverse stellar populations. However, inference typically requires computational…
KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb: Mass Measurements for Two Super-Earth Microlensing Planets
Keming Zhang, Sean K. Terry, Joshua S. Bloom +2
KMT-2018-BLG-0029Lb and OGLE-2019-BLG-0960Lb were the lowest mass-ratio microlensing planets at the time of discovery. For both events, microlensing parallax measurements from the…
An Earth-Mass Planet and a Brown Dwarf in Orbit Around a White Dwarf
Keming Zhang, Weicheng Zang, Kareem El-Badry +8
Terrestrial planets born beyond 1-3 AU have been theorized to avoid being engulfed during the red-giant phases of their host stars. Nevertheless, only a few gas-giant planets have…
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…
Stellar Spectra Fitting with Amortized Neural Posterior Estimation and nbi
Keming Zhang, Tharindu Jayasinghe, Joshua S. Bloom
Modern surveys often deliver hundreds of thousands of stellar spectra at once, which are fit to spectral models to derive stellar parameters/labels. Therefore, the technique of Amo…
Constraints on the Progenitor System of the Type Ia Supernova SN 2011fe/PTF11kly
Weidong Li, Joshua S. Bloom, Philipp Podsiadlowski +25
Type Ia supernovae (SNe) serve as a fundamental pillar of modern cosmology, owing to their large luminosity and a well-defined relationship between light-curve shape and peak brigh…
