Removing systematic errors for exoplanet search via latent causes
Bernhard Schölkopf, David W. Hogg, Dun Wang +4
We describe a method for removing the effect of confounders in order to reconstruct a latent quantity of interest. The method, referred to as half-sibling regression, is inspired b…
An Ultraviolet-Optical Color-Metallicity relation for Red Clump Stars using GALEX and Gaia
Steven Mohammed, David Schiminovich, Keith Hawkins +3
Although core helium-burning red clump (RC) stars are faint at ultraviolet wavelengths, their ultraviolet-optical color is a unique and accessible probe of their physical propertie…
Computer-aided Recognition and Assessment of a Porous Bioelastomer on Ultrasound Images for Regenerative Medicine Applications
Dun Wang, Kaixuan Guo, Yanying Zhu +3
Biodegradable elastic scaffolds have attracted more and more attention in the field of soft tissue repair and tissue engineering. These scaffolds made of porous bioelastomers suppo…
A pixel-level model for event discovery in time-domain imaging
Dun Wang, David W. Hogg, Daniel Foreman-Mackey +1
Difference imaging or image subtraction is a method that measures differential photometry by matching the pointing and point-spread function (PSF) between image frames. It is used…
A Causal, Data-Driven Approach to Modeling the Kepler Data
Dun Wang, David W. Hogg, Dan Foreman-Mackey +1
Astronomical observations are affected by several kinds of noise, each with its own causal source; there is photon noise, stochastic source variability, and residuals coming from i…
General Framework for Twisted Bilayer Photonic Crystal with Interlayer Coupling and Far-Field Response
Shupeng Xu, Dun Wang, Ritesh Agarwal
We develop a general theory for twisted bilayer photonic crystals that takes into account both far-field response and near-field coupling. The theory is based on the framework of a…
