Preprocessing Solar Images while Preserving their Latent Structure
Nathan M Stein, David A van Dyk, Vinay L Kashyap
Telescopes such as the Atmospheric Imaging Assembly aboard the Solar Dynamics Observatory, a NASA satellite, collect massive streams of high resolution images of the Sun through mu…
Detecting Unspecified Structure in Low-Count Images
Nathan M. Stein, David A. van Dyk, Vinay L. Kashyap +1
Unexpected structure in images of astronomical sources often presents itself upon visual inspection of the image, but such apparent structure may either correspond to true features…
BAHAMAS: new SNIa analysis reveals inconsistencies with standard cosmology
H. Shariff, X. Jiao, R. Trotta +1
We present results obtained by applying our BAyesian HierArchical Modeling for the Analysis of Supernova cosmology (BAHAMAS) software package to the 740 spectroscopically confirmed…
A method for comparing non-nested models with application to astrophysical searches for new physics
Sara Algeri, Jan Conrad, David A. van Dyk
Searches for unknown physics and decisions between competing astrophysical models to explain data both rely on statistical hypothesis testing. The usual approach in searches for ne…
Detecting Abrupt Changes in the Spectra of High-Energy Astrophysical Sources
Raymond K. W. Wong, Vinay L. Kashyap, Thomas C. M. Lee +1
Variable-intensity astronomical sources are the result of complex and often extreme physical processes. Abrupt changes in source intensity are typically accompanied by equally sudd…
