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…

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…
