Residual Entropy as a Diagnostic and Stopping Metric for CLEAN
The Astronomical Journal, 2023 We propose the use of entropy, measured from the spatial and flux distribution of pixels in the residual image, as a potential diagnostic and stopping metric for the CLEAN algorithm.

Efficient Range Estimation in Beat Radio Interferometry
IEEE Access, 2017 The beat radio interferometry (BRI) is a novel ranging scheme that achieves high accuracy with low-cost devices. A major problem with BRI is the lack of an efficient range estimation method that is valid in general measurement configurations and ...

Interferometry and the study of protoplanetary disks*
EPJ Web of Conferences, 2015 Interferometry offers access to scales that are unresolvable using single dish telescopes, which is especially important when investigating objects with small angular sizes, such as protoplanetary disks.
